Tools and methods of panning for sand gold, methods of panning for gold in the sand

Tools for panning for gold:

Jigs. Chutes, shakers.

Wait. The method of panning for sand gold: panning for gold in the sand is commonly known as panning for sand gold, and there are many ways to pan for sand gold, among which the re-selection method is the most effective and economical method for panning for sand gold.

In the early days, sand gold was mainly washed by hand, from which coarse-grained gold or other heavy metals could be obtained. With the development of society and the progress of human beings, gold mining technology and equipment have been greatly improved, and large-scale mechanized gold mining projects have emerged. Gongyi Metalworking Machinery Factory hereby introduces several gold mining equipment and methods, hoping to help relevant people.

Extended information: Gold accounts for a large proportion of waste rock.

The proportion is smaller. Therefore, according to the principle of gravity separation, gold can be easily separated from sand gold ores. Gold mining equipment is also mainly gravity separation equipment, such as jigs, chutes, vibrating screens, etc.

Jigs have a great advantage in terms of ****, especially rough gold, ** rate.

It can reach 95%, and has the advantages of high efficiency, energy saving and environmental protection in mineral processing. It is the equipment of choice for gold panning in stationary gold concentrators and large gold mining vessels. The placer gold mine enters the jig, and after the jig, high-grade gold can be obtained.

Concentrate. Also weighed, heavy sand can be treated by mixing mercury or shakers to further enhance pure gold.

What is the Golden Horse River? There are a lot of equipment about gold panning, what do you want to do? Mechanical mining or the archaic way?

There are shiny yellow particles in the sand, I soaked it in hydrochloric acid to blacken, and the mercury is not soluble, it should not be **.

How to learn in the sand of knowledge: panning for gold in the sand.

Tools for panning for gold: jigs, chutes, shakers, etc.

There are many ways to pan for sand gold, among which the gravity method is the most effective and economical method for panning for sand gold.

In the early days, sand gold was mainly washed by hand, and the river sand was simply washed and processed to obtain coarse-grained gold or other heavy metals. With the development of society, the progress of human beings, the process and equipment of panning for gold have been improved to a great extent, and there is a large-scale mechanization of the gold panning project.

The specific gravity of gold is larger, and the specific gravity of waste rock is smaller, so according to the principle of gravity separation, gold can be easily separated from the sand gold mine, and the equipment for sand gold is mainly gravity separation equipment, such as jigs, chutes, shakers, etc. The jigging machine has great advantages for gold, especially for coarse-grained gold, its rate is as high as 95%, and has the advantages of high efficiency, energy saving, environmental protection and other mineral processing, and is the preferred sand gold panning equipment for stationary gold concentrators and large-scale gold mining ships.

The sand gold ore enters the jig, and the high-grade gold concentrate is obtained through jigging beneficiation, and the heavy sand can be treated with amalgamation or shaker to further purify the gold.

Principle: Because the chemical properties of ** are stable, generally do not react with other substances, so it exists in the sand and gravel in a free state, under the natural weathering, the rock is broken, and finally forms sand and soil, and the granular golden sand is buried in it, under the washing and carrying of flowing water, the particles of sediment and gold move together with water.

They move at different speeds and states, so in a certain area of the riverbed can form a rich area of golden sand, that is, people are eager to find the gold panning ground, people set up gold panning equipment here, dig the river sand into the gold panning bucket, and then pump the sand in the river water bucket, a large amount of sand is carried away by the water, and what is left in the bucket is the golden gold.

1. Because the chemical properties of gold are stable and generally do not interact with other substances, it exists in the sand and gravel in a free state.

2. The density of gold is much greater than that of sand, and the sand particles are carried away by the current under the impact of water, while the gold remains in the container.

The principle of gold panning in the sand.

Sand gold is heavier than sand and will sink to the bottom of the pan.

1. Due to the chemical properties of gold.

Stable, generally does not interact with other substances, so it is in a free state.

Found in the sand, in the town of Santan.

2. The density of gold is much greater than that of sand, and the sand particles are carried away by the water under the impact of water, while the royal tung gold remains in the container.

The principle of gold panning in the sand.

The principle of gold panning, the equipment for panning for gold in the sand in the river, the working principle of placer gold beneficiation equipment**.

Panning for sand gold is "panning for gold in the sand", using various methods and equipment to dig gold out of the sand, here is a brief introduction to the principle and method of panning for sand gold.

Gravity separation is the most efficient and economical method of sand gold beneficiation, and in actual production, gravity separation is also the main method of panning for sand gold. The principle of gravity separation method is to let gold and sand stratify according to the specific gravity with the help of external force in the medium, so that the light and heavy minerals are separated, and the specific gravity of gold is much greater than that of sand, so the process of separating light and heavy minerals and the process of panning for sand gold, the heavy product is gold and other heavy minerals, and the light product is sand and waste rock.

There are many ways to pan for sand gold, but each one is based on gravity beneficiation, the earliest human beings used the method of manual washing to wash out the gold from the sand, etc., and later there were some gold selection equipment such as jigs, chutes, etc., which greatly improved the efficiency of panning for sand gold, and the rate of gold was also greatly improved. When it comes to sand gold panning equipment, here is a brief introduction to several sand gold panning equipment:

1. Chutes. The chute is the simplest gold panning equipment, its manufacturing cost is low, the maintenance cost is low, and even the maintenance cost is almost non-existent, and the amount of sand is large, but the chute is also the lowest rate in the gold selection equipment, the worst effect, the use of the chute gold selection lost gold can be regarded as an astronomical amount. Large-scale concentrators and gold mining ships do not use this equipment as a coarse and selective placer gold.

2. Shaker. The shaker is also a kind of gravity beneficiation equipment, and the gold separation of the shaker has a good effect and rate, but the processing capacity of a single shaker is small, the area is large, and the amount of sand output is small, resulting in the shaker can not be directly used for the beneficiation of sand gold, but only used in conjunction with jigging and other equipment, as the selection equipment of sand gold.

3. Jigger. Jigging machine is one of the most effective equipment for placer gold selection, which combines the advantages of chute and shaker, with large processing capacity, small footprint, good rate and beneficiation effect, relevant information shows that the sawtooth wave jigger as a gold selection equipment when the rate is as high as 98%. Large-scale gold concentrators and gold mining ships use jigs to coarse and select sand gold.

Due to the stable chemical properties of **, generally do not react with other substances, so it exists in the sand and gravel in a free state, under the natural weathering, the rock is broken, and finally forms sand and soil, and the granular golden sand is buried in it, under the scouring and carrying of flowing water, the particles of sediment and gold move together with the water, and the speed and state of their movement are different, so in a certain area of the riverbed can form a rich area of golden sand, which is the gold panning land that people are eager to find, and people set up gold panning equipment here. Dig the sand of the river into the gold panning bucket, and then pump the sand in the bucket, a large amount of sand will be carried away by the water, and what is left in the bucket is golden gold. For example, the Jinsha River in Sichuan is a famous gold rush zone, and it is said that a gold mining boat is worth a million, and the lucky gold diggers can recoup the cost in a month.

This is how gold panning works in the sand.

The density of gold is much greater than that of sand, and under the impact of water, the grains of sand are carried away by the current, while the grains of gold remain in the container. In the principle of gold panning in the sand, because the chemical properties of gold are stable, generally do not interact with other substances, so it exists in the sand and gravel in a free state, under the natural weathering, the rock is broken, and finally forms sand and soil, and the gold is buried in it, under the transportation of the stream, the sediment, gold particles and water move together, they move at different speeds and states, so in a certain area of the riverbed can form a rich zone of golden sand, which is the gold panning land that people are eager to find, and people set up gold panning equipment here, Dig the sand of the river into the gold panning bucket, and then pump the sand in the bucket, a large amount of sand will be carried away by the water, and what is left in the bucket is golden gold.

Hand panning is released with chemicals.

Some private gold mines in Lazhu are using this method, which is seriously polluted) smelting (commonly speaking, it is set on fire to burn, because the melting point is different) The relative efficiency of the latter two is high.

The ancient Romans used a kind of alfalfa grass.

Stir with the golden sand in the water.

Plants adsorb fine ** particles in water.

Then put the plant in the fire to make a difference.

This is the origin of the Western call for alfalfa grass as clover.

Gold generally exists in the form of elements in nature, and it is mainly a physical method. The method of seeing the socks is to pan for gold, using the density of gold, and the water washes away the light sand, and the rest is gold. However, the obtained gold still needs to be chemically purified.

Wash the sand with water, like washing rice. Of course, you can also pour in mercury and filter the sand out, and then heat the mercury, but this method is easy to be poisoned by mercury, and with potassium hydride, this is also easy to poison.

The development of flotation method.

In ancient China, the natural hydrophobicity of the mineral surface was used to purify mineral drugs such as cinnabar and talc, so that the mineral fine powder floated on the water surface and the useless waste rock particles sank. When panning for placer gold, the feathers dipped in oil were used to catch the lipophilic and hydrophobic gold and silver fine grains, which was called goose feather scraping gold at that time.

The principle of flotation.

The surface of the mineral particles is hydrophobic or hydrophobic or enhanced by the action of flotation agents. Hydrophobic, which is lipophilic and gasophilic, can accumulate at the liquid, gas, or water-oil interface.

Flotation agent. During flotation, various agents are used to adjust the physical and chemical properties of the selected minerals and flotation media, so as to expand the difference in hydrophilicity between gold minerals or gold-bearing minerals and gangue stones, so as to make them better sorted and achieve the purpose of increasing the gold rate.

Flotation equipment. Flotation equipment is mainly flotation machine and other equipment for the realization of flotation process. The slurry is agitated and aerated, and the ore particles adhere to the bubbles under the action of various flotation agents, and the bubbles rise to form a mineralized foam layer, which is scraped out or overflowed by the scraper, and this series of flotation processes are completed in the flotation machine.

The flotation machine is mostly composed of multiple tanks connected in series.
