Pyrite flotation process. As flotation also can be used for pyrite ore separation, though flotation separation has deficiency with considerable large investment in equipment, higher mining cost, while better efficiency and index in mining with simple flotation reagents, so flotation methods can be used for low grade pyrite ore

Apr 01, 2021 1. Introduction. Froth flotation is an important and versatile separation technique in the mineral processing industry for recovering valuable minerals from mining ores (Aghazadeh et al., 2015).Froth flotation is a physico-chemical separation process based on the differences between the surface wettability of valuable and valueless components (Wills and Finch, 2015)

There are two methods for pyrite mineral processing which are gravity separation and flotation separation. Gravity separation is often used for processing medium particle disseminated pyrite ore with good separation performances. The specific gravity of pyrite is higher, which can reach to 4.9-5.2
