For Heavy Calcium Molybdenum Ores Flotation Cell

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, which is based on Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new

In case of primary sources, such as Mo ores or Mo-containing Cu ores, molybdenum sulfide is enriched and separated from gangue and copper by gravimetric methods and flotation. If necessary, several detrimental contaminants are subsequently removed by leaching prior the roasting of the sulfide to crude molybdenum oxide.

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further

Cupric sulfate is a salt created by treating cupric oxide with sulfuric acid.This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as blue vitriol.The anhydrous salt is created by heating the hydrate to 150 °C (300 °F). Cupric sulfate is used primarily for agricultural purposes, as a pesticide, germicide, feed additive, and soil additive.
