Introduction to Mineral Processing or Beneficiation

In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.

14.6: Applications of Thermochemistry

The heat of vaporization of water (an endothermic process) is clearly found from the diagram.; Hydrogen peroxide H 2 O 2, which spontaneously decomposes into O 2 and H 2 O, releases some heat in this process. Ordinarily this reaction is so slow that the heat is not noticed. But the use of an appropriate catalyst can make the reaction so fast …
