electrostatic separation wolframite in south africa

Abstract. Wolframite is often associated with calcium bearing minerals, leading to low grade, while conventional anionic collectors are hard to realize their efficient flotation separation, thus the effective structural modification of cationic collectors provides a new insight into enhancing the comprehensive development of wolframite resources.

Electrostatic separation, as the name suggests, works on the principle of charge differences. When subjected to an electric field, particles with different properties acquire charges at varying levels. Following this, the charged particles experience an electrostatic force in the electric field. The disparity in the obtained forces results in a ...
