Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade …

1.2 Ores and Minerals. Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or …

There are chemical differences between minerals and components when using the chemical method. By leaching with acids and ammonia, solid metal minerals are dissolved into liquids. To produce copper sulfate solution from malachite ore, dilute sulfuric acid is used to soak the ore, and copper ions are replaced with iron ions.

Mineral beneficiation is the process of concentration, and was first described in Agricola's famous treatise, De Re Metallica, published in 1556. The earliest ores to be discovered and processed were of such high grade that they did not require beneficiation, and they satisfied mankind's needs for nearly 3,000 years. By the end of the ...
