These ores are often sent direct to the smelters for treatment A fifth type is the disseminated ore type They are often low in grade but large They fill large fracture and fault zones or replace certain geologic horizons They are the result of the circulation of large amounts of heated water deep underground Character of Gold Ore Bodies

Contrasting Surficial Composition of Native Gold

The particle size distribution of concentrates depends on the type of gold bearing ore and the size of native gold It is often assumed in the literature that gravity concentrates contain larger 212 μm coarse grained free gold However the use of centrifugal concentrators has expanded the range of particle sizes in the obtained concentrates
