Method and apparatus for the flotation of sulfide minerals from sulphide-containing ores

摘要

A process for the recovery by flotation of sulphide minerals from ores whereby a pulp of the ground ore is conditioned in at least one agitation conditioning stage in the pH range of about 8.0 to 12.0 in the presence of a sulfhydryl anionic collector, after which the conditioned pulp is subjected to flotation to produce a concentrate high in the desired sulphide minerals recovery and a tailings impoverished in the desired sulphide minerals.
