After acid bulk flotation, copper has been separated by flotation using conditioning of the pulp with a modified starch (dextrin) and lime at high pH to depress other sulphides (Lukkarinen, 1962). Ores are usually ground conventionally in drum mills using either steel grinding media or autogenously with the ore itself.

ABSTRACT The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in the gangue matrix so that conventional gravity concentration using spirals and shaking tables would be ineffective. The actual …

Beneficiation begins with crushing and grinding to reduce the grain size and physically separate valuable copper (and other) minerals from minerals with no economic value also present in the ore. Collectively, valueless minerals are known as 'gangue' and they are ultimately disposed of as a waste called 'tailings', which is a mixture of ...
