The world practice for processing gold ore in the last decade is widely used process of heap leaching of gold cyanide solution of alkali metal. By present time in the mining industry of the Republic of Kazakhstan, this process has been developed only in recent years, in connection with the advantages of this method of ore processing are not fully identified. At present the field Bakyrchik there are problems with the extraction of precious metals due to the high content of carbonaceous shales and arsenic. It is expected that the use of new native strains thiobacteria extraction of precious metals will rise. The effectiveness of work - the results show the availability of thiobacteria isolated directly from the field to improve recovery of precious metals in the processing of ore Bakyrchik. Experience in the use of foreign technology by bioleaching industrial products obtained from the processing of ore deposit, proved to be inefective because of the high arsenic content.
