Abstract
A method of recovering free milling gold from a gold-containing feed material that includes processing at least a part of a tailings stream from a flotation element in a size separation element and producing a fines stream and a coarse stream. The method also includes recovering free milling gold from at least one of the fines stream and the coarse stream.

1-24. (canceled)
A method of recovering free milling gold from a gold-containing feed material, the method comprising:
- (a) passing a feed stream of the gold-containing feed material through a flotation element and producing (i) a concentrate stream and (ii) a tailings stream;
- (b) processing at least a part of the tailings stream in a size separation element, and producing a fines stream and a coarse stream;
- and
- (c) recovering free milling gold from the fines stream.
A plant for recovering cyanide soluble gold from a gold-containing feed material, the plant comprising:
- (a) a flotation element operable to produce (i) a concentrate stream and (ii) a tailings stream from a feed material;
- and
- (b) a size separation element operable to process the tailings stream and produce a fines stream and a coarse stream;
- and
- (c) a recovery unit operable to recover free milling gold from the fines stream.
