Abstract

The present invention relates generally to a process for flotation of sulphide minerals where a flotation pulp is separated into a coarse stream and a fine stream, preferably containing particles coarser than about 30 micron and particles finer than about 30 micron, respectively. Typically, alkali and depressant are added to the coarse flotation stream only and acid and activator are added to the fine flotation stream only. During flotation of the fine stream, acid and/or activator may be added at the conditioning, cleaning, re-cleaning, cleaner-scavenging or third cleaning stage. During flotation of the coarse stream, alkali and/or depressant may be added at the conditioning or cleaning stage.
