Gold & Silver Leaching Methods
In Situ Leaching In situ (inplace) leaching offers attractive benefits for producing metals at a minimum of capital investment and operating cost, with low environmental degradation The technique has not been applied to gold and silver ores, primarily because of fear over public reaction to using cyanide solutions where ground waterBlasts designed for in situ copper leaching must produce adequate fragmentation and permeability for successful leaching Copper recovery depends to a large extent on the particle size distribution created by the blast, the permeability in the blastfractured zone, and the ability to maintain solution flow with a minimum amount of channelingNIOSHTIC2 Publications Search Some
