Figure 1 - Gold ore characterization flowsheet (Brooy, 1994) The selection of a flowsheet for free milling ores is relatively simple compared to others. The major factors include comminution circuit selection, heap leaching use, treatment of ores with high silver content, and flotation options for sulfides.

The selection of an appropriate crushing and comminution circuit for a specific ore type is one of the most important key aspects in a new gold project. The importance is related to the fact that the capital and operating costs for generated for these operations represent the major part of the plant operative costs (65-70% of the total cost).
3. Comminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry ...
