Froth Flotation Process Used in the Lead Zinc Sulfide Ore

2020-2-20  The most common lead-zinc sulfide ore is lead-zinc sulfide polymetallic ore. The lead-zinc sulfide is often associated with a variety of valuable components, such as lead, zinc, copper, sulfur and other useful minerals, whose floatability is obviously different, which determines the different froth flotation process of lead and zinc sulfide ores. The common froth flotation process of sulfide ore mainly

Describe the Extraction of Zinc Metal from Its Sulphide

2021-6-30  Roasting: Zinc blende is subjected to roasting, i.e. it is heated in the presence of excess air. This converts zinc sulphide ore to zinc oxide. The reaction involved is: Reduction: Zinc oxide is then reduced by coke (carbon). When zinc oxide is heated with coke, carbon acts as a reducing agent and reduces zinc oxide to zinc metal.
