Iron Ore Reverse Flotation Introduction Xinhai

On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral. Because the density of gangue ore is smaller than that of iron ore, reverse flotation method shows a better flotation performance with lesser flotation reagents, which reduce the

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

Flotation Simple English Wikipedia, the free encyclopedia

Flotation is used to separate sulfide ores from the impurities in the ore . A detergent is added to the mixture and it is stirred. The sulfide minerals float, while the gangue sinks to the bottom and is removed. This is used in making zinc, where zinc sulfide is a major zinc
