Sulfide Ores - an overview ScienceDirect Topics

VMS ore-forming fluids are acidic, reduced, 1–3 M chloride solutions in which metals were transported mainly as chloride complexes (Table 3).Before the discovery of black smokers, temperatures of the ore fluids were estimated from rare fluid inclusion data and sulfur isotope fractionation between sulfide mineral pairs. pH values about 1 unit less than neutral (~5 at 250 °C) were determined ...

2018-8-1  Lead-zinc ore requires sequential flotation with galena being floated first, followed by the flotation of sphalerite. In a typical industrial flow-sheet (Bulatovic, 2007), the overall process is divided into two stages (lead and zinc flotation) with lead concentrate and zinc concentrate being the products. There is also a tailings stream.
