  1. The gold purification process uses the king water dissolved gold, and then adds the reducing agent to restore the gold, or to interfere with the substance of the mask, and then the extraction method. This requires a large amount of reducing agent or extracting agent, which is high. The present invention breaks through the traditional craftsmanship. It adopts simple purification processes such as the gold -king water, combined with acid removal, high temperature melting, etc. to obtain high -quality gold. Compared with existing technology, the invention has the characteristics of high product purity, low production cost, and simple and practical process. A kind of wet purification of the gold technology, which is to place coarse gold in a container, add the newly prepared Wang Shui to flood the thick gold, and then heat it for 15-25 minutes. Completely dissolved, remove the cooling, add a slightly water rinsered wall, filter, wash it with water until there is no yellow filter paper, the filter liquid is merged with the washing fluid, which is characterized by heating the obtained solution to dry. Add no gold mud with thick hydrochloric acid, blow the cup wall with water and steam it repeatedly. After cooling, add 1: 1 hydrochloric acid solution to cook for 1-2 times. The added hydrochloric acid can be drowned. , Filter, wash it with water without chlorine -free ions, transfer the gold mud into another container, and then wash it with 1: 1 nitric acid solution for 1 to 2 times. Wash, dry it, put the gold mud into the magnetic cricket, add a small amount of borax, melt into a pure gold block at 1000 to 1100 ° C

  2. Gold is a natural product that exists in a free state in nature and cannot be artificially synthesized. According to the different sources and the different contents of the content, the content of raw gold and cooked gold.
    This gold, also known as natural gold, waste gold, and original gold. It is the object of cooked gold. It is a gold that is unlimed from the mine or river base layer and has not been melted and refined. There are two types of gold and ore gold and sand gold.
    Mine gold, also known as the alleged gold, produced in mines and gold mines. After mining, crushing, and washing, large gold can be picked directly, and the small grains can be dissolved in mercury. Mine gold is mostly accompanied by other metals. Among them, in addition to gold, there are other metals such as silver, platinum, and zinc. Before other metals were proposed, it was called a precursor. The other metal components produced in different mines are different. Therefore, the percentage is different, generally between 50%-90%.
    The sand gold is produced at the bottom of the river or a low -lying area, so the stone sand is mixed together and washed out of the gold. Sand gold originated in the mine, because the gold ore was exposed to the ground. After a long wind and rain, the rocks collapsed in the north wind, and the gold was separated from the sand and the water. Deposition is a gold -containing layer to form sand gold. The characteristics of sand gold are: different sizes of particles, large on the size of broad beans, small ones like fine sand, different shapes. The color is different due to the height of the formation. More than 90 % of them are red yellow, eight percent of them are pale yellow, and seven become cyan yellow.
    Matonous gold is the gold that has been smelted and purified by the gold. Generally, the purity is higher and the density is fine. Some can be directly used in industrial production. Common gold bars, blocks, ingots, and various accessories, utensils, gold coins, and industrial gold silk, pieces, boards, etc. Due to the different uses, the required color is different, or because the device is not purified, it is only melted without purity, or the purity of the mention is insufficient, forming a different golden height. People are accustomed to three types: pure gold, red gold, and color gold according to the height. According to the different gold content, it is divided into color gold, mixed gold, and K gold.
    The gold that reaches a fairly high purity after being purified is called pure gold, which generally refers to gold that reaches more than 99.6%.

    This and pure gold are close to the mind, but due to the different time and local standards, the standards of Chijin are different. The gold sold in the international market is 99.6%of Chi Jin. The red gold in the territory is generally between 99.2%-99.6%.
    It color gold, also known as "secondary gold" and "tide gold", refers to the low color. Due to the different metal content of these gold, the high color is 99%high, and only 30%of the low.
    If is divided by different metals, gold can be divided into color gold, mixed gold, K gold, etc. The color gold refers to gold only mixed with silver components, regardless of whether it is high or low. There are more color gold, commonly in gold bars, ingots, blocks and various utensils and gold jewelry

Pay content for time limit to check for freenAnswer Hello, I am a respondent in the financial field, "Talking about stocks and gold", and has been engaged in financial and legal work experience for many years. I have seen your question. Time, please wait patiently. I will provide you with the most detailed answers in 5 minutes, and will not reply to you, thank you!nHello, dear, I am glad to answer this question for you. Refining gold can pour concentrated nitric acid and gold into the cup. After that, put the cup on the cup rack with wine essence. Essence In addition, refining gold can also be configured with nitric acid and hydrochloric acid at a ratio of 1 to 3, put the metal in the king water until the reaction is over, and finally heated and put in copper slices for replacement. 1. The nitric acid separation method can be used to refine gold can be used to 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, put the cup on the cup frame, and heat it with alcohol lamps. After that, you can get sliced ​​gold. After becoming a king water, put the metals that need to be refined into the king water, and filter 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. Sulfuric acid hydration separation method, mix sulfuric acid and hydrogen peroxide in a ratio of one to one, and then put the technologies that need to be refined into the sulfuric acid hydraulic solution. After the metal reaction is over, the yellow metal object obtained is gold. I hope my answer is my answer. It is helpful to you! grateful,nAsk how to refine gold in the ore, how to detect the gold content in the 2kg heavy ore?nPlease wait a moment, I am looking at your question, dearnQuestion [Bi Xin]nAnswer dear, the content of gold in the ore is extremely low. In order to extract gold, you need to crush 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 Use this method to choose goldnIn addition, dear, the gold content in the ore can be detected by the atomic absorption of lighting. It is a type of instrument analysis. Compared to the methods of chemical method and other current instruments, it is easy to deal with, almost no interference, mature technology, accurate, fast speed, and can measure PPB levels, but there are no small ones. It's the best choice, dear,nIf you have any other questions, you can consult me ​​or leave a message at any time, and I will reply to you as soon as possible, dear,n6 morenBleak
