graphite hydrated tailings

Chapter 5b GARDGuide

For instance preferential deposition of heavier sulphide minerals may result in a tailings beach having a higher AP than the tailings leaving the processing plant The exposed AP of waste rock may be higher than predicted by analysis of pre mine drill core or pre blast hole chips if sulphides preferentially report to waste rock fines Table 5 5
