Production and Supply Cobalt Institute

Cobalt is widely scattered in the earth’s crust and is found in a variety of different ores in several countries. Cobalt is only extracted alone from the Moroccan and some Canadian arsenide ores. It is normally associated as a by-product of copper or nickel mining operations. Around 55% of the world cobalt production

Laboratory-scale sulphation roasting testwork for copper

2017-5-22  Roasting of sulphide concentrates, in particular copper and cobalt concentrates from central Africa, is a well-established unit operation in the extraction flowsheet of these elements. In a typical copper-cobalt production flowsheet shown in Figure 1, the purpose of roasting is to selectively convert the copper and cobalt sulphides into sulphates that are readily leachable in water or dilute mineral acid, while the undesirable iron forms oxides that are insoluble under these leaching conditions (Guntner & Hammerschmidt, 2012; Palperi & Aaltonen, 1971). Fluid bed roasters are typically used to react wet concentrate with air in an autothermal manner. Developments in fluidized bed techniques have made it possible to firmly control process conditions such as temperature, material distribution and reaction gas atmosphere (Guntner & Hammerschmidt, 2012). Under these controlled conditions, cobalt and copper occur primarily as sulphates which are subsequently leached, while iron compounds form oxides that are insoluble under mild leaching conditions. The recovery of cobalt and copper
