ABSTRACT:
The present invention comprises a process for the separation of ore components by flotation comprising: grinding ore to form pulp, mixing said pulp with sulfide ions and cyanide ions, adjusting the concentration of said sulfide ions to a level at least sufficient to cause depression of base metal mixed sulfides but insufficient to cause substantial activation of pyrites, and adjusting the concentration of said cyanide ions to a level at least sufficient to cause auxiliary depression of the mineral components of said ore which are required to be depressed in said flotation, but insufficient to cause overdepression of said mineral components; said sulfide ions and cyanide ions having been introduced to said pulp at predetermined times and in a predetermined sequence.
