Flowsheet considerations for copper cobalt projects

Copper and cobalt production from oxide ore types in the African Copperbelt by agitation leaching followed by solvent extraction (SX) and electrowinning (EW) has been practiced for many years. The Tailings Leach Plant at Nchanga in Zambia was commissioned in 1974 and is still in operation today1. In recent years, more of these types of plants

How to Use Copper Sulfate As a Fungicide |

The best time to spay a plant with a copper sulfate fungicide is before leaf out in the spring or after leaf drop in the fall to prevent damaging the leaves. However, if you must spray during the growing season, use a diluted mixture of the fungicide as follows: 1/3 tbsp. copper sulfate to 1/3 tbsp. hydrated lime to 1 gallon of water.

Copper For The Garden: What Copper Does For

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. Therefore, maintaining fair amounts of copper for the
