A model is proposed to simulate the operation of a dry rotary drum magnetic separator. The model uses a probability distribution of the trajectories followed by the particles ejected from the rotating drum of the magnetic separator. Empirical relationships are used to relate the particle trajectories following their ejection to the drum rotation speed and magnetic …

Vermiculite is mined from a separate pit, located adjacent to the copper pit. The mining operation involves blasting the ore in the pit, which is approximately 50 metres deep, loading the ore onto trucks, and transporting it to the surface, where it is then sent to the nearby Vermiculite Plant. The pit is a lot shallower than the open copper pit.

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to study the …
