2 thoughts on “How to refine gold from ore”

  1. The content of gold in the ore is extremely low. In order to extract gold, it is necessary to break and grind the ore and use the mineral method to be enriched or separated from the ore. The use of gold in gold is re -selection and flotal. The re -election method occupies a very important position in the production of sand gold. The flotation method is the method of choice for the widely used in rock gold mines. At present, about 80%of the rock gold mines in my country With this method selection, the mineral selection technology and equipment level have been greatly improved.
    (1) Crushing and grinding ore
    (2) Re -selection and re -election is widely used in the rock gold mine, mostly as auxiliary processes, recycling coarse gold in the grinding circuit, which is flotal and cyanocyan Chemical crafts creation favorable conditions, improving the mineral selection indicators, increasing the total recovery rate of gold, and played a positive role in increasing production and reducing costs.
    (3) Floating According to surveys, about 80%of the rock gold mines in my country adopt a flotation method, and the concentrates produced are mostly sent to non -color smelting factories for treatment. Due to the increasing development of cyanide funds and in order to improve economic benefits and reduce the loss of concentrate transportation, the product structure has changed greatly in recent years. Waiting for the problem, forcing the mining to deal with themselves on the spot) to promote the development of flotation technology, and occupy a considerable position in gold production.
    (4) Releasing-water and smelting gold biscuity process 1. Saltic mixed mercury and gold and mercury mixing method are an ancient gold biscuity technology, which is simple and economical, suitable for coarse-grained monolithic gold Recycling. Many gold mines in my country are also using this method. With the development of gold production and the advancement of scientific and technological, the gold mixing method has been continuously improved and improved.

  2. Pay content for time limit to check for freenAnswer Hello Baidu lawyer serves younHello, 1. The nitric acid separation method can use the nitric acid separation method, pour the thick nitric acid into the cup, and put the metal that needs to be refined into the cup. After that, the cup is placed on the cup frame, and at the same time heated it with alcohol lamps, and then you can get pieces of gold. 2. Wang Shui separation method can also use the Wang Shui separation method to refine the gold. After configured a part of nitric acid and three copies of hydrochloric acid into Wang Shui, put the metal that needs to be refined into the king water, and filter it after the metal reaction is over. Then heated it, and finally put it in the copper piece for replacement, which can also be refined. 3. The sulfuric acid hydration separation method mixes sulfuric acid and hydrogen peroxide in a ratio of one to one, and then puts the technology that needs to be refined into the sulfuric acid hydraulic solution. After the metal reaction is over, the yellow metal object obtained is gold.nQuestion how gold is refinednAnswer 1. First crush the gold ore. 2. Put it in a large pool with a water solution with sodium cyanide to make gold dissolved in sodium cyanide. (Having toxic) 3. Collect the sodium cyanide solution and put it in metal silver (or copper) for replacement reaction. 4. Put the silver embryo after the response into the high temperature of the dish melted, remove the silver -copper residue on the melting surface, and get a rough gold. To get more pure gold, further refinement is needed.nAsk how to refine the gold on the mobile phonenAnswer to open the phone case with a screwdriver and take out the circuit board. Drop all the things on the circuit board. Use pliers to remove the electronic components on the electronic board, leaving only the complete electronic version. Other mobile phones do the same processing. Next, the circuit board of the mobile phone is crushed with a pieces. Finally, soak the crushed circuit board with Wang Shui, and then filter it to make gold.nQuestion concentrated nitric acid, and Wang Shui, where are you selling?nAnswer Wang Shui is generally used to dissolve non -lively metals, such as gold and platinum. Professional chemical drug stores are sold and can also be made by themselves.n6 morenBleak
