To overcome percolation problems, a major improvement was made with the introduction of agglomeration prior to ore placement. If the ore particles and/or agglomerates are of similar size, segregation can be avoided to a great extent (Heinen, 1980, Herkenhoff and Dean, 1987, Kinard and Schweizer, 1987, McClelland et al., …

These problems routinely occur in silos discharging in a funnel flow pattern, in which some material moves while the rest remains stationary. Funnel flow occurs when the sloping hopper walls of a silo are not steep enough and sufficiently low in friction for material to flow along them. Particles slide on themselves rather than the hopper walls.

The presence of copper sulphides in the ore reacting with cyanide requires oxygen similar to gold, according to Elsners equation. If the ore has 7 ppm Au and 460 ppm copper then it is not hard to see the effect on the oxygen demand. Oxygen sparging will assist, however if the oxygen level drops then the leach kinetics will be affected.

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
