Crushing Plant Flowsheet & Design-Layout
The extent to which fine crushing can be carried out will vary and depends on the ore characteristics, plant and crusher design. Unfortunately, the ore characteristics are generally beyond our control, so the concentration of effort lies primarily on the plant arrangement, equipment design and operation.
Gold and Silver Extraction
Examples of non-refractory gold ores include placer, free milling and oxidized ores. Gold particles in the non-refractory gold ores are not locked, and nearly 95% of the gold from non-refractory gold ores can be recovered by gravity concentration and/or direct cyanidation. The treatment options for non-refractory gold ores are shown in Fig. 5.1.
