Beneficiation of graphite fines from moulding factory mine wastes

Multi-gravity separators (MGS) and shaking tables are being used in coal processing and heavy minerals beneficiation. In the present study, the possibility of using MGS and shaking table to separate graphite from moulding sand is analysed on the basis of investigations carried out. The effect of change in different process variables on concentrate sand content and graphite recovery values is studied. Several parameters, thought to be effective on the separation were tested. After the shaking table experiments a graphite concentrate was obtained having 4.51% sand content with 60.83% recovery. After the investigations carried out by multi-gravity separator, a graphite concentrate was obtained having 0.95% sand content with 68.00% recovery.
