(PDF) Some factors that affect beneficiation of sulphide nickel–copper

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.
