acid washing tank gold ore flotation best

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
