Mining: crushing-grinding costs.Extracting useful resources from mined ores requires comminution. This is the integrated sequence of crushing and grinding operations, which breaks down mined rubble (3-10 cm diameter), effectively into talcum powder (30-100µm), which can in turn enter the metal refining process with sufficient surface area to extract …

The weighted average of the year composites, based on the mine plan, is estimated to achieve an overall average gold recovery in the range of 93% to 94%. The initial design daily throughput is 16,000 tonnes per day, with an availability of 75% used in designing the crushing circuit and 93% for the design of the rest of the plant.

of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation
