At present, there are about 300 kinds of iron ore in nature. According to their chemical composition, iron ore can be divided into magnetite, hematite, limonite and siderite. But according to the different magnetization coefficient of iron ore, iron ore is divided into strong magnetic and weak magnetic minerals, which provides the basis for the selection of …

Phosphorite exploitation especially agricultural consumption majorly relies on the availability of phosphorous (P). Mostly, the plant availability of P in soil is influenced by associated mineral such as it depends on Magnesium (Mg) and Calcium (Ca) when soil has pH > 8 and by Iron (Fe) and Aluminum (Al) when soil has pH < 5.5.

Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or "matrix" as it is called locally, contains three different mineral groups which have to be separated from each other.
