In the modern gold mining industry, two methods of obtaining precious metals are actively used. The first method is called hydraulic; it consists of washing gold out of the rock under the influence of a stream of water supplied under high pressure. However, the second method, based on the use of a special machine, is much more effective.
A dredge for gold mining is a huge device the size of a 4-story building and a weight that reaches 1,400 tons. The unit operates afloat, its design includes a whole complex of scoops that lift rock from the bottom of the reservoir, and from this rock by washing get gold ore.
The wide functionality of the dredge allows you to perform the entire range of tasks for the development of placer deposits, starting with the extraction of rock and its delivery to the washing site and ending with waste disposal.
To operate this colossus, the simultaneous efforts of 9 people are required, but the productivity of the device is simply amazing, it is equal to the efforts of 12 thousand miners, “armed” with primitive trays.
World gold mining
Nowadays, gold mining is not an exciting adventure that ruins some people and makes others rich. Now, this activity has become an actively developing type of income.
Enterprises that are engaged in industrial gold mining maintain accounting records, calculate economic feasibility, and conduct geological exploration using modern technologies. That is, it provides a workplace for many people with different professions.
Rating of leading countries in gold production
Dozens of countries account for global gold mining, and the Russian Federation is no exception. Gold nuggets here are rarely found on the surface of the earth, however, at some depth underground, there are so many gold deposits that it allowed the Russian Federation to take fourth place in the production of this noble metal in the world. Today, Russia holds 7% of the world's total gold reserves.
The absolute leader in gold mining since the early eighties has been the Republic of South Africa, which provides about 70% of all gold production. Although, in the early nineties, South Africa's income fell by 35% due to a decrease in exploration of new gold deposits. And some states, such as Australia, on the contrary, have begun to increasingly develop underground and surface gold deposits located on its territory.
Features of the board with the GENE FIT chip
The mod turns on as standard, press fire 5 times and turn the device on or off.
The display contains monochrome symbols that indicate battery charge (2 symbols), resistance, voltage, tightening time and power in watts.
If you screw on the atomizer, the box mod will ask if the atom is new and after the choice is made, it automatically adjusts the power to the resistance.
The operating mode changes after three clicks on fire.
We immediately get into thermal control, where you can switch to submodes: SS, Ni, Ti.
On thermal control, the power does not rise above 80 W.
Next, you can switch to FIT mode. This is a thermal control for Uforce tanks. The mode has symbols 1, 2, 3, which allows us to increase or decrease the power.
Simultaneously pressing “+” and “-” allows you to go to the next mode, where we can more accurately adjust the mode of temperature or power curves.
There is also a function that allows you to adjust the set resistance, as well as add or reduce the temperature coefficient value.
The combination of the “+” and fire buttons will block all buttons.
Pressing “-” and “+” at the same time will flip the screen.
Surfing through the menu allows you to see the firmware version - V 1.000.
Methods of gold mining in Russia
Over time, gold mining methods have constantly improved and changed. At first, manual gold mining was widely used by sifting sand in water.
Then people mastered the extraction of noble metal from ore. These days, manual gold mining is a rarity. This process is mostly automated, but that doesn’t make it any easier. After all, to find a profitable deposit you need to spend a lot of effort and money. A payable deposit is considered to be one in which there are 3 grams of pure gold per 1 ton of soil.
More recently, in the gold mining industry, a method called amalgamation has been popular. Its peculiarity is the use of mercury placed at the bottom of the container. The barrel was filled with gold-bearing ore and shaken. As a result, gold particles remained in the mercury at the bottom of the barrel. The main negative quality of this method is the high toxicity of mercury.
Nowadays, gold is separated from ore using sodium cyanide. Thanks to the advent of this method, it became possible to extract gold from previously abandoned deposits, which returns their profitability.
Gold is also mined using dredges - surface-mounted mining machines equipped with everything necessary to extract metal from the ground. Dredging only works in areas with certain soil. This must be a watery area, so such special vehicles are often installed near river banks or other bodies of water.
Program for Drag mini
To update the firmware, follow the link to the manufacturer's official website.
Despite the absence of Drag mini among other mods, download the firmware -V1.5.1.38.
Next, connect the mod to the computer and click connect.
Firmware capabilities: adjust resistance and temperature curves. By the way, doing this on a computer is much more convenient.
In addition, you can increase or decrease the cutoff duration, as well as add screen brightness (this can only be done from a computer).
Well, logos can be transformed, or you can add your own.
What is a dredge?
A dredge is a device that is directly related to gold mining. The weight of this device reaches several hundred tons. This is a mechanized unit equipped with buckets operating on the principle of a chain excavator. On board the floating platform there is everything you need to wash rock and sand. A large dredge can be controlled by a crew of up to 10 people, while a small special vehicle requires only one manager.
Dredge design diagram
The cost of dredging for gold mining is available only to large enterprises. Before installing this machine, you need to remember that this idea may be unprofitable if the content of precious metals in the soil is low.
Therefore, before using this special vehicle, it is necessary to carry out a number of reconnaissance activities, including geological research and chemical analysis of the soil composition to determine the concentration of noble metal in it. Only in this case will the profitability of industrial gold mining be justified. In addition, installing a dredge requires a lot of effort and time, since the machine is quite heavy and bulky.
Box mod review
On the top there is a metal round part of the connector pad; it protrudes slightly above the body and slightly makes the atomizers hang down.
The connector itself has a spring-loaded brass pin, the spring is elastic.
Thanks to the central location of the connector, you can screw on atomizers up to 25 mm without sides. The picture below shows a Manta Tank.
The overall body is made of zinc alloy and the cover is made of Resin. It is solidly assembled and well-painted, at least in my version, with a lava color.
The elements of the body part, which are on the side, look like linings, but they are not removable.
On one part the name is “DRAG”, on the second there is a resin insert. It is very pleasant to hold in your hands, the sensation is tactile.
The end part contains a metal fire, a monochrome display, minus and plus buttons, also made of metal.
Even lower is the port for connecting the microUsb cable.
At the bottom there are openings for the removal of gases and ventilation of the board. There is also a RESET button, which can be pressed with a sharp object, such as a needle. She answers to reset the settings if the vape hangs or if something goes wrong.
Classification of dredges
Dredges are grouped:
- by the type of energy required for the operation of the device: electricity, energy from the combustion of gasoline or diesel fuel vapors;
- by depth of work with rocks below the water level: shallow-water, deep-water;
- by bucket capacity: small, medium, large;
- by maneuvering method: rope-pile, rope-anchor.
As a rule, two types of special machines are used for gold mining:
- marine;
- continental.
These types of dredges differ in that the marine special vehicle is similar to a ship that can be moved along the coast, while the continental one requires more resources, as it is mounted on a pontoon.
Smaller special vehicles called mini-dredges are ideal for individual gold miners or prospectors. They can either be purchased in special stores or made independently. The mini-drag has been significantly reduced in size. Its weight ranges from 25 to 100 kg.
A positive feature of using mini-dredges is that they reduce labor costs and speed up the gold mining process. Therefore, the interest of miners in constructing the unit with their own hands at home is justified.
Review of the Uforce T2 atomizer: types of evaporators and possible glasses
The atomizer has a very beautiful 810 acrylic drip tip, the color of which will match the side panel of the mod. It's o-ring, but I think there's no point in choosing mine, it's so beautiful.
The drip type has downward slants when viewed from above. All condensation will not accumulate on top, as is usually the case, residual drops will flow into the tank.
Dimensions:
Height:55mm
Fit diameter / with Bubble Glass: 24 mm / 28 mm
Volume with straight glass / with Bubble Glass: 3.5 ml / 5 ml
Weight: 60 gr.
Despite the sharp edges of the drip tip, it is pleasant to use, it does not dig into the lips, and the sensation is pleasant when applied.
Top filling with a slide to the side, opening is quick, the hole for a bottle of liquid is large, the Chubby Gorilla spouts fit easily.
The atom spins counterclockwise. When disassembled, it consists of 5 parts: drip tip, top cap, evaporator, glass, base.
The evaporator is pre-installed, marked P2, with a resistance of 0.6 Ohm, power from 24 to 28 W. He's on the net.
There is N1 in stock, where the cross-section of the mesh is larger. The resistance is already 0.13 Ohm, and the recommended vaping power is from 70 to 80 W.
The evaporators are screwed onto the base at the bottom, and from the top, the elongated part of the shaft, which is combined with the top cap, is screwed onto the top of the coil.
There are three air ducts on the base, which are quite large. There is a tightening adjustment ring on the side.
There is a floating pin at the bottom that does not stick out and this tank cannot be used on mechanical mods.
About volume. The Voopoo website presents as many as 10 types of evaporators labeled: U2, U4, U8, N1, N2, N3, R1, D4, P2. There is even an RBA database.
About glass.
Again, the guys from Vupu offer a rich palette of glasses; there are two types of Bubble Glass, one 5.5 ml and 8 ml. There are also 2 ml (TPD), 3.5 ml and 5.5 ml straight glasses.
The taste is on the evaporators on the mesh. Buck copes well with this.
The atomizer comes with lubricant, so you first need to disassemble and wash it.
Operating principle of the dredge
Externally, the mini-dredge looks like a vacuum cleaner that sucks up sand and gold dust in order to separate one from the other. All possible models of these special vehicles differ in size and materials from which they are assembled, but their structural elements are similar:
One type of mini dredge
- a system that provides buoyancy of the device;
- drive responsible for the operation of the centrifugal pump;
- injector;
- washing chute for separating precious metal from slag;
- air supply system for breathing underwater.
Metal extraction using a mini-dredge is divided into 3 stages:
Mini dredge gold mining scheme
- pumping water under high pressure into the injector chamber;
- then water with sand and earth is sent to the washing trench to separate the noble metal from the slag;
- the drive starts the pump to sift out the gold in the trough.
The performance indicator for all devices is different, but on average it ranges from 100 to 1000 kilograms of processed rock per hour. Before you start working with a mini-dredge, you need to clear the bottom of the reservoir from stones, because they can clog the unit.
Mini-drag Afalina 1000
A miniature gold dredge is an effective and popular unit for gold mining. It is modernized over time and becomes more and more popular in prospecting circles. First, you need to seriously invest in the purchase or assembly of the device, but then this investment will bring considerable profit.
Before assembling homemade mini-dredges, you need to know that gold mining without a license is prohibited in the Russian Federation. Along with this, artisanal mining of this precious metal is close to crime.
General impression
I really liked Modik. It is beautiful, perhaps in the color that was flown to us for review.
The quality of the paint is excellent; during a week-long test of the device, nothing broke off from the body. Overall the device is built to good quality.
At the same time, the device from the Zaparka video channel became chipped during use. Perhaps it was just poorly painted.
The charging current is 1.8 A, and until fully charged you need to wait approximately 2 hours 15 minutes.
The device cannot be used while charging, that is, there is no Passthrough mode.
It was experimentally established that the batteries here are connected in series and are not of the 18650 format.
Vupu claims that the capacity ratio in the Drag Mini is the same as two 18650 batteries, but it doesn't say there are two 18650s inside.
In terms of capacity, they lied a little, pointing to 4400 mAh, in fact there is 3000 mAh.
For this reason, the device cannot be used with TFV12 or other tanks that produce large clouds of steam.
This device is closer to the stealth format, for cigarette tanks or single-spiral drips - an excellent solution.
You can, of course, use double-coil drips, but it all depends on your vaping style.
If you vape too much, the battery will quickly run out, and you will have to wait 2 hours for it to charge.
