Fine coal processing

Mineral Technologies’ LC3 spiral separator was designed specifically to meet our customer’s requirements – eight turns with continuously changing trough profiles. 

Comparative test results show that the LC3, with its unique trough design, is capable of d50 cut points. That is significantly lower than those achievable with conventional coal spirals. The ability to target a cut point in the sg range 1.45 to 1.60, opens up new possibilities for coal processors who recognise the operational simplicity and reliability of spiral separation. 

The LC3 has demonstrated effectiveness at reducing losses of clean coal to reject, considerably enhancing processing capability. 

Testing also indicates that the LC3 is effective in traditional applications with traditional cut points, making it attractive for selection in a flexible and robust processing solution.
