"The possibility to introduce our technology into gold production will be affected by [world market] prices for an ounce of gold," NUST MISIS Professor Vadim Tarasov explained, commenting on the new production method.
"With our technology, we get 85-90%" of the gold out, "which is a standard and most viable figure," Tarasov said.
Contrary to centuries-old stereotypes about how gold is actually produced, today most of the precious metal is extracted from the ground not in the form of nuggets or gold dust, but through the chemical processing of copper and other ores which contain it.
At the moment, the price for an ounce of gold is hovering at around $1,250 US.
But scientists from the University, together with their Chinese colleagues, have come up with a new method for chemical extraction, which reduces extraction costs by 30-40%. The method adds ammonia to the cyanide compound. The technology is between four and eight times faster than the standard chemical method, and is far less exposed by unwanted impurities such as copper. This will allow miners to spend much less time, effort and resources to separate gold from copper.
The University says the new method can be used at all gold mines in Russia.
Furthermore, according to Vadim Tarasov, the same technology can be used to extract gold from old electronics.
