FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

(0 50%). Therefore, gravity recovery is usually followed by additional gold recovery operations such as cyanidation and/or flotation. The amenability of a gold orebody to gravity treatment is dependent on the size and liberation characteristics of the individual gold particles in the ore. Relatively coarse gold
