• Gold ore Carbon-In-Leaching (CIL) processing technology

    The flotation tailings containing the unrecovered gold from the primary circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL).

    In CIP, the carbon is mixed with the cyanide leach solution, and agitated in the leach tanks, and agitated with the ore while the gold is being dissolved. This assures a rapid interface between the carbon and the gold loaded cyanide solution. Granular, hard carbon is used, in the size range of 10-16 mesh.

  • 4 Reasons and Solutions of Poor Gold Leaching Effect

    Because the carbon contained in the ore has considerable activity, the phenomenon of "carbonaceous gold robbing" will occur during the leaching process. They will adsorb the dissolved gold and then precipitate it again, thereby reducing the gold leaching rate. Solution. According to the carbon content of these kind of ores, physical and

  • In situ leach Wikipedia

    In-situ leaching (ISL), also called in-situ recovery (ISR) or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.In situ leach s by artificially dissolving minerals occurring naturally in a solid state. For recovery of material occurring naturally in solution, see: Brine mining.
