Copper-Nickel Ore Processing. Table of Contents. A nickel-copper sulphide concentrate was treated in a pilot plant at Warren Spring Laboratory during 1961, by a hydrometallurgical roast-leach-solvent extraction process devised to cleanly separate the metal values, and produce acid sulphate liquors containing the metals.

Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are …

A few studies report the use of rhamnolipid biosurfactants as frothers in copper ore (Khoshdast et al., 2012b) and in coal (Khoshdast et al., 2011, Khoshdast and Sam, 2011) flotation processes, indicating that the use of rhamnolipid surfactant significantly increased the flotation rate of all minerals. Also, the collected interfacial …

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal.
