NICKEL AND COBALT ORES: FLOTATION

2016-6-7  Cobalt minerals are generally recovered as by-products during the extraction of zinc, copper, nickel,silver etc. Flotation of cobalt sulRde ores can be bestachieved at acidic pH (4) with xanthate collectorsand at pH of about 7.5 for oxide ores with nitroso-naphthol chelating reagents, while their mixture isrecommended for oxidized sulRde ores.

Nickel And Cobalt Ores Mining dressing Flotation Plant ...

Application of cobalt flotation : 1. Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc, copper-zinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expanded to include the oxidized minerals, non-metallic ores and fine coal.

Projects — Missouri Cobalt

Missouri Cobalt has completed commissioning on its new froth flotation facility; the Madison Mine Processing Plant (MMPP). Froth Flotation is the most widely used method for ore benefaction whereby valuable minerals are separated from other non-valuable minerals by inducing them to gather in and on the surface of a froth layer.
