Review on Beneficiation Techniques and Reagents

Highly crystallized and coarse-grained phosphate ores have a good processibility. Hence, it is of great necessity to achieve a relatively high degree of mineral liberation and to avoid overgrinding concurrently. Depressants and collectors are the key reagents during the flotation process.

An Overview of Calcite Recovery by Flotation

2020-9-23  Cationic reagents are generally used for flotation of silicate impurities from calcite ore. However, there are few Nordic high-grade calcite ore deposits with sulphides and graphite as impurities. Generally, different kinds of amines were used as cationic reagents to float the undesirable impurity minerals from this calcite ore.

Review on Beneficiation Techniques and Reagents

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.
