Mar 01, 2015 The successful removal of silica mineral particles and silica-rich coal particles from raw coal using electrostatic separation techniques to preconcentrate coal could greatly benefit the further coal processing. This study investigates the rotary triboelectrostatic separation of a fine coal and silica mixture (0.151 mm) to simulate the coal and silica minerals, which commonly exist in run of mine
The enhanced separation capabilities of the STET system may be a very effective alternative to flotation processes. An economic comparison conducted by an independent mineral processing consulting firm of the triboelectrostatic belt separator versus conventional flotation for barite/quartz separation illustrates the advantages of dry processing for minerals.
