Abstract

In recent years, there have been trends in the expansion of enterprises specializing in the extraction of metals, which is likely to remain in line with the long-term, longterm plans of large enterprises. Most small gold and other metal mining companies do not have such prospects. However, without replenishing the subsoil, the underground resources will continue to run out. For small businesses, it is advisable to adopt a new technology of selective smelting of deposits, as this method has a number of technical and economic advantages over traditional technologies of gold mining.
