Gold mining process development denver mineral engineershe flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyritesn a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure.
201964usually a gold ore is labelled refractory when a standard cyanide leaching test yields recovery below 70 have not found results of any leaching tests in the papern which basis the authors have decided to label the ore as refractory gold it is not because the ore contains pyrite that it is refractory.
Copper gold ore flotation machine perkinspreschool ith the advent of flotation and the fact that gold either free or finely disseminated in pyrite, etccould be floated, many possibilities opened up for the treatment and concentration of gold ores.
froth flotation is a process for selectively separating hydrophobic materials from hydrophilicis is used in mineral processing, paper recycling and wastewater treatment industriesistorically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
