Comminution Circuits for Gold Ore Processing
For modern large gold plants, the most typical flowsheets are crushing circuits (for heap leaching), autogenous/semiautogenous (AG/SAG) ball-mill circuits, or HPGR-ball-mill circuits. Such flowsheets dominate the 20 largest gold producers in Table 17.1. Examination of the flowsheets within each category, though, also demonstrates that the …
