The rational utilization and treatment of tailings have always been an important issue in the development of mineral resources. The tailings generated during copper mining often contain valuable metals such as gold in addition to copper. How to effectively extract gold from copper tailings can not only improve resource utilization efficiency, but also bring additional economic benefits to enterprises. This article will provide a detailed introduction to the extraction technology of gold from copper tailings.
The physical beneficiation method mainly includes methods such as reselection, magnetic separation, and electrostatic selection. These methods mainly utilize the differences in physical properties of minerals, such as density, magnetism, and electrical properties, for sorting.
Re selection method: Using gold with a higher density than other minerals, separation is carried out through equipment such as shaking tables and chutes.
Magnetic separation method: For magnetic minerals, a magnetic separator is used for separation.
Electric selection method: Using the electrical differences of minerals, sorting is carried out through an electric selection machine.
The chemical beneficiation method mainly achieves the enrichment and separation of valuable metals by reacting chemical reagents with minerals.
Flotation method: use flotation agent to make the surface properties of gold different from other minerals, and realize separation through foam flotation.
Cyanide method: Dissolve gold in cyanide solution, and then recover gold through zinc displacement or activated carbon adsorption.
Thiourea method: using thiourea as a leaching agent to selectively dissolve and recover gold.
Biometallurgy is an environmentally friendly extraction method that promotes the dissolution and enrichment of gold through microbial metabolism.
Microbial leaching: using specific microorganisms to dissolve gold from gold mines, and then recovering it through subsequent processes.
In actual production, a single beneficiation method often fails to achieve the ideal gold recovery rate, so a combination of multiple beneficiation methods is usually used.
Heavy flotation combined method: first enrich gold through re-election, and then further improve the gold recovery rate through flotation.
Magnetic chemical combination method: first remove magnetic impurities through magnetic separation, and then extract gold through chemical methods.
