Russian scientists have found that gold can also be obtained from coal! And at least one gram can be extracted from a ton of coal. Scientists are studying the extraction method, which has been patented.
Scientists from Amur State Science Center, Far East Branch of Russian Academy of Sciences are studying how to extract at least 1g of gold from every ton of coal burned by boilers.
At present, the experimental device has been equipped, and it is planned to be implemented in a boiler room in Amur Prefecture in 217.
According to the data, this gold extraction work is based on the analysis of the coal composition in different mining areas in the past 15 years. Scientists believe that there is about 1 gram of precious metal in each ton of coal in the Weitzky mining area of Erko.
But at present, no one in China has found gold in coal mines. It's just other substances.
because coal mines are generated in sedimentary rocks, gold can only be generated in magmatic rocks.
What you see is something called pyrite, also called native copper. The chemical formula is ferrous sulfide FeS, which is like brass in color and crystalline. It is the raw material for sulfuric acid production in industry and is common in coal seams.
Purpose Pyrite is an important chemical mineral raw material, which is mainly used to produce sulfuric acid. Part of it is used in chemical raw materials to produce sulfur and various sulfur-containing compounds. It has important uses in rubber, paper, textile, food, matches and other industries and agriculture. In particular, it is used in the national defense industry to manufacture various explosives, smoke agents, etc. Sulfuric acid is made from pyrite, and its slag can be used for ironmaking and steelmaking. If the slag has high sulfur content and low iron content, it can be used as an auxiliary raw material of cement-mixture. In addition, pyrite often occurs with copper, lead, zinc, molybdenum and other sulfide deposits, and contains gold, cobalt, molybdenum and rare element selenium, which can be comprehensively recycled. ? But sometimes where there is pyrite, there is usually gold.
