A study on the possibility of improving sulfide ore preparation characteristics using the pneumatic separation process

The size, density of the particles and their shape play a significant role in the effectiveness of the pneumatic separation process. An experiment held using a lab machine revealed that the shape of the particles affects their warping from the air-flow. Research has shown that the airflow produced with the flat or narrow side of the ore which are flat and have a large form factor are more likely to be affected by the warping process. The impact of the ore shapes on the results of separating the pieces in terms of their density during the pneumatic separation process can be decreased by producing a structured feed-through into the air-flow using the flat side or by improving the previously selected ore pieces of a flat shape.
