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 …Web

The froth flotation as a nickel concentrating process from lateritic deposits has not been as successful as the recovery of Nickel from sulfide deposits. However, several investigations have been conducted trying to find alternatives to increase nickel concentration in laterites and oxidized ores [ 3, 9 ].Web

At the second stage the dependence of the distribution of nickel in the fineness classes of flotation products on the content of the fineness class −0.071 mm in the feed was studied. The purpose was the formation of an algorithm for the simulation model of the flotation process of copper-nickel ore enrichment.Web
