Flotation of Gold and Gold-Bearing Ores - ScienceDirect

 · It is widely accepted that the main purpose of in the flotation of sulfide gold carriers is to enhance the flotation of the sulfides and, in particular, pyrrhotite Mitrofanov and Kushnikova, 1959, arsenopyrite Gegg, 1949, OConnor et al., 1990, and pyrite Bushell and Krauss, 1962. The sequence of addition before or after the collector is important.

Minerals - Gekko Systems

When gold is associated with sulphides, it can be either fully encapsulated by the sulphide particle or partially liberated, i.e. exposed on the edge of the sulphide mineral. Sulphide complex gold can occur in a wide range of particle sizes.

Gold extraction -

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for…
