Basic Principles and Calculations in Chemical Engineering
Material balance involves calculations the quantities of all materials that enter and leave any system or process which are based on the principle of the "law of conversation of mass". This law states that matter is neither created nor destroyed in the process and the total mass remains unchanged.

Mineral dressing (= Orebeneficiation)
Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...

Vitamins and minerals: a brief guide
A mineral is an element that originates in the Earth and always retains its chemical identity. Minerals occur as inorganic crystalline salts. Once minerals enter the body, they remain there until excreted. They cannot be changed into anything else. Minerals cannot be destroyed by heat, air, acid, or mixing. Compared to other nutrients such as protein, carbohydrates and fat, vitamins and ...
