Gold Mining Process Development – Denver Mineral Engineers

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.

Flotation stabilization and optimization

Process control and optimization have a direct influence on the efficiency of flotation plants. An inefficient operation can cause an incorrect balance between grade and recoveries and can also lead to adverse shifts in the grade-recovery relationship. Flotation loses the largest proportion of valuable

US5171428A

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 - ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings
