GCA Mineral Concentration Specialists

The Consep Acacia Reactor is a complete intense leaching plant that maximises the recovery of gold from gravity concentrates. Often used downstream from FL Knelson Concentrators, the Acacia produces the optimum solid liquid interaction for maximised gold leaching kinetics by using an up flow fluidised reactor as opposed to complex mechanical agitation.

In general, therefore, leaching is most rapid and most complete when the mineral being leached is ground to very small particle size and the greatest possible surface area (e.g. up to 27 m 2 /g) is exposed per unit volume of culture. With minerals whose sulphates are insoluble, or concentrates containing lead sulphide with Cu, Cd and Zn, the total amount of metal extracted

Solid Liquid Extraction (( Leaching

Leaching: is the separation of a solute from solid mixture by dissolving it in a liquid phase. Leaching occurs in two steps: 1. Contacting solvent and solid to effect a transfer of a solute (leaching). 2. The separation of the solution from the remaining solid (washing). Factors influencing the rate of extraction: There are four important factors to be considered: 1. Particle

The capacity of the vat is approximately 10000 m 3, the depth up to 6 m. Larger containers may take up to 12 000 tonnes of ore and are filled and emptied mechanically. Small production plants use the dosing regime, but in large plants, only the semi continuous or continuous regime is efficient. In the continuous regime, there is at least one vat outside the circuit and it is emptied

Gold Mining Equipment for Sale JXSC Machine

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, the CIL process lowers the gold mining operation cost and increase the gold recovery rate to a degree of 99%. It has become the first choice of modern gold mining and beneficiation plant design.

Gold Refining From Gold Ore to Doré World Gold Council

When gold dissolution is complete, the gold bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators. For extracting gold from low grade ores, heap leaching is practiced;
