Copper is an essential element for plant growth. Soils naturally contain copper in some form or other, ranging anywhere from 2 to 100 parts per million (ppm) and averaging at about 30 ppm. Most plants contain about 8 to 20 ppm. Without adequate copper, plants will fail to grow properly.
The copper cement can be removed at the end of each cycle or after several cycles of operation. ACID SUPPLY. The source of sulphuric acid for leaching is usually a major consideration for small plants. If the plant is located in an area where acid can be purchased at low cost, one of the greater items of capital expense can be avoided.
Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market. Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation.
