hydrometallurgical process for the separationand recovery

The proposed hydrometallurgical process for nickel recovery from real sulphate heap leach liquors consists of the following six (6) unit operations: Removal of iron, aluminium and chromium, as easily filterable crystalline basic sulphate salts of the jarosite–alunite type, at atmospheric pressure, by chemical precipitation at pH: 3.5 and 95 °C. Cobalt, manganese and magnesium extraction over nickel …

Hydrometallurgy is used since the early 20th century for zinc, copper and aluminum. In the 50s, this process is suitable for treating lateritic nickel ores. Several steps are used to extract nickel and cobalt from laterite and the Great South produce nickel oxide and cobalt carbonate: The pulping ore. Get Price

Hydrometallurgy, or “hydromet” for short, is a metal processing technology that uses a chemical process combining water, oxygen or other substances in a pressurized or other vessel to dissolve a metal from its ore, concentrate or an intermediate product (such as matte). The nickel industry worldwide has traditionally smelted concentrates produced from nickel, copper and cobalt sulphide ores to make an …

PuriTech has built up a lot of experience with its ION-IX technology in hydrometallurgy in the last few years. Adsorption of the nickel and cobalt is done over two or three stages thus providing an increased length to contain the mass transfer zone. Because the cobalt and the nickel have a different elution zone all metals can be recycled back
