Mineral resources are characterized by different properties and the flotation process depends on many factors which must be carefully controlled to obtain an expected separation efficiency of the process under industrial conditions. These facts determine the complexity of mineral processing structure.
Gold Processing. Gold is usually present as a metal, alloyed with metallic silver and perhaps, copper. The high S.G. (19.3) of gold means that that gold particles, even when of sub-sieve size, settle readily from pulps in which the main gangue mineral is silica.
