Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive primary operations are comminution and concentration, but there are other important operations ...

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used .
The beneficiation study of veintype apatite from Mushgia Khudag deposit, Mongolia, was carried out to gain knowledge for processing an extremely REEenriched igneoushydrothermal ore type associated with Upper Jurassic–Lower Cretaceous, c. 140 Ma, syenite magmatism.. In the field, the studied apatite veins range from centimeters to several meters in width and crosscut the syenite.
