leaching copper pilot plant

The flowsheet contemplates a six to seven dayleach-washcycle with one tank being discharged and charged each day. Inleaching plantsof capacity illustrated by this flowsheet recovery ofcoppernormally effected range from 80 to 90% ofoxide copperand 70% or more ofsulfide copperfrom average ores.

    Pressure Oxidation (POX) is a process used to extract gold,copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.

    Oct 01, 2016· Thepilot plantwas built in the Gobi Desert. The six heaps operated well at heights from 1.4 to 4.1 m. Detailed investigations of the permeability,copper leachingrate, acid consumption and water evaporation showed that heaps of − 40 mm ore leached for 68 days produced acopper leachingrate of up to 85.8%.

    >CopperHydrometallurgicalPilot PlantCore recently carried out an oxidativeleach pilot plantto demonstratecopperrecovery from a low grade chalcopyrite concentrate. The project investigated hydrometallurgical options for recovery ofcopperin flotation tailings, that would be sent to the tailings dam from acopperprocessing circuit.

    Theoretically, 2/3 of the total leach liquor in the Bagdad dumps has been treated in the pilot plant, without any apparent effect on the leaching efficiency in the dump* It should be noted, however, that the acid consuming Bagdad dumps are principally oxide mineralization, thus do not rely to a large extent on bacterial action for solubilization of the copper.

    From 1996 to 1997, Mines Gaspé operated apilot plantto test the economic feasibility ofleachingan oxidizedcopperore, followed by SX and EW ofcopper. Despite the fact thatcopperSX–EW processes have the reputation of being low-cost operations,plantengineers should always look at ways to make theplantmore efficient.

    We then calculate the sum ofcopperdigested during these three digestions and compare the calculatedcopperto a totalcopperassay. The data gathered during this testing is important for flowsheet development andpilot plantdesign. SGS sequentialleachingis a reliable solution to complexcoppermineralogy in gold orebodies.
