Gold CIL Carbon in Leach Process is an efficient design of extracting and recovering gold from its ore By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99

US8114365B2 - Silica removal from pregnant leach solutions

The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution PLS More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed

Copper Chloride Leaching Process - Outotec

Our copper chloride leaching process utilizes our highly effective atmospheric chloride leaching technology, including gold and silver recovery We have coupled this with world-renowned VSF solvent extraction and electrowinning technology to make a process that is especially effective with low-grade and impure copper feed materials

How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

The process design of gold leaching and carbon-in-pulp circuits

The CIL process The carbon-in-leach CIL process, illustrated in Figure 3 is a variation of the CIP process In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously Capital cost is reduced, as only one set of agitators for both leaching and

Leach Residue and Pregnant Liquor Separation Process and

Separation of leach residue suspended solids from pregnant liquor solution is an important step in hydrometallurgy flowsheets Alternative flowsheet options are counter-current decantation CCD thickeners or counter current washing CCW horizontal belt vacuum filters Extensive sedimentation and vacuum
