Copper Tailings Leaching Plant Zambia

The large quantities of ore, overburden, and rock are separated at the mine site and the rock is hauled to the waste site. The ore is crushed, mixed with other low-grade ore, and chemically leached to remove the copper.

During the leaching process, weak acids are allowed to seep through copper-bearing rocks dissolving copper and any radionuclides present in the soil. The leached liquid containing the dissolved copper, known as a pregnant leach solution, is later collected and further processed to extract the copper.

The liquid leachate may lead to TENORM contamination in the surrounding environment by seeping into the groundwater at abandoned and active copper mining sites. Zenith developed complete range of copper tailing leaching plant in Zambia and copper recycling plant for sale.

Copper Tailing Leaching Plant

Although the heap leaching is a low cost-process, it normally has recovery rates of 60-70%, although there are exceptions. It is normally most profitable with low-grade ores. Higher-grade ores are usually put through more complex milling processes where higher recoveries justify the extra cost. The process chosen depends on the properties of the ore.

Zenith is the world leader in copper processing and tailing recycling technology, we developed complete series of copper tailing leaching plant Zambia, including copper extraction plant, copper crushing machine, copper pulverizer, screening plant, washing machine, separation machine, processing plant etc.

Zenith technology and service covers the complete range, from feasibility studies, plant design and equipment manufacture to project implementation and installation of process plants. If you are interested, please feel free to contact us, we will provide you best service.

Copper Tailing Smeling Machine

Roasting - Ore concentrates are roasted or heated to remove sulphur and moisture.

Smelting - Copper concentrates are mixed with silica (sand) and limestone then heated in a furnace to form two immiscible (naturally separating) layers. One layer is waste consisting of iron and silica compounds and is discarded as slag. Approximately 75% of the copper concentrate ends up as slag. The other layer called "matte copper" consists of copper, iron sulfide, and other metals.

Converting - Matte copper is transferred to a converter, where more silica is added to help separate it into a copper-rich slag, which is returned to the crusher, and "blister copper," which is sent to another furnace for casting.
