A group of specialists from Russia, representing nust “MISIS”, in collaboration with scientists from China presented a method of extracting gold from ore, which allows to reduce the cost of this metal by more than a third. The introduction of this technology, unlike others, will not require huge expenditures, the researchers said.
Scientists remind us that today gold is rarely find in the form of nuggets or gold dust, as it was in centuries past. To date, the main method to help replenish the reserves of the precious metal, is a chemical treatment of the various containing gold ores, including copper. The most popular modern method involves the use of water and easily connects with gold cyanic acid. According to experts, this method is quite effective, but it requires a large amount of time and financial costs.
A new method, proposed by chemists, resembles the above, but involves the use of amikeca along with cyanic acid. According to the calculations, which were conducted by specialists, this will allow you to cut costs in the gold production by 30-40 percent, and the rate of this production is to accelerate at four to eight times compared to the classical technology. The specialists assure that gold will be less susceptible to the effects of unwanted impurities.
As the researchers note, the new method has already shown its effectiveness on the gold mine in Tajikistan and in the other two, located on the territory of Chelyabinsk region. Application of the developed technology allowed to reduce the required on processing time fivefold.
Experts add that the new technology can be used for gold mining not only from ores, but also from the defective or outdated electronics.
