Q: What is electrostatic separation in ore concentration?

Electrostatic separation is a process that uses the charge difference between various minerals for mineral processing. In ore concentration, it's often used to separate valuable minerals from their ore bodies. The principle of electrostatic separation is that different minerals have different electronegativities, which gives them different charges after …
