Phosphate Testing - KEMWorks

Beneficiation is the process where ore is reduced in size and impurities separated to achieved the required Minor Element Ratio or MER in the concentrate (rock) and P 2 O 5 grade. [MER is defined as (% Fe 2 O 3 + Al 2 O 3 + % MgO / % P 2 O 5)]. Low MER is important for the rock to be processed to phosphoric acid and fertilizers.

Minerals | Free Full-Text | Review on Beneficiation ...

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 phosphate ore is, hence, of great necessity.
