Our standard packages are for process plants of: 25 Tonnes/Day = 1 Tonne/Hour. 50 Tonnes/Day = 2 Tonne/Hour. 100 Tonnes/Day = 4 Tonne/Hour. 250 Tonnes/Day = 10 Tonne/Hour. This is a standard process plant which includes only the major components of the complete metallurgical flowsheet.

In the unique cell, copper is plated at the cathode and the oxidizing component is regenerated at the anode to be recycled back to leaching. This unique cell design allows the system to operate in a closed loop with no effluent discharge. The process has been successfully tested in a small scale pilot plant on: Copper scrap

copper cathode per year. The concentrate is thickened to about 60% solids in a 50m diameter thickener, and pumped to continuously agitated storage tanks, 12 m in diameter x 12m high, that provide surge capacity between the filter plant and the hydrometallurgical plant. Two belt filters filter the concentrate and wash out impurities.

Copper electrorefining mainly produce LME Cu-CATH-1 copper cathode and byproduct anode slime from copper anode. Metalcess develops mini scale copper ER from 1T/d copper electrorefining system with modular design/easy installation, saving installation instruction cost and optimizing your return on investment.

Copper cathode is the primary raw material input for the production of copper rod for the wire and cable industry. The major uses of copper cathodes are in the manufacture of copper rods for the wire and cable industry and copper tubes for consumer durable goods. Copper cathodes are also used for making alloys like brass, bronze and alloy steel ...

In 2000, small-scale mining in Chile was responsible for the production of some 45,000 metric tons of copper, 13,650 kg of silver, and 3,500 kg of gold, representing 0.97%, 1.1% and 6.5% of national production, respectively. The sector overall employs an estimated 1,700 workers, some 5.1% of the country's mining labour force.

The plant produced more than 40 tonnes of LME A-grade cathode copper from a complex polymetallic, chalcopyritic feed concentrate. In 2008, two fully integrated pilot plants were operated. In one instance, the feed was a low-grade chalcopyritic concentrate from the RTB Bor Copper Complex in Serbia, and in the other the feed was a low-grade ...
