Development of the electrochemical hydrochlorination in the pulp technology of arsenic-pyritous gold ore of the Republic of Kazakhstan's deposits


Short description:


The technology for processing resistant gold ores and concentrates by electrochemical hydrochlorination in the pulp method with a high (~ 85-95%) rates of extraction of gold from raw materials to the commercial product. This method is an alternative to cyanide leaching, and has the following advantages:

  • high degree of extraction of gold;
  • significant simplification of the process scheme;
  • reduce of process life.


Level of readiness:


Technology is ready to testing.


Availability of patents:


Technology is protected by documents of title of the USSR and RK.
