    There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.

    Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows.
