Though these costs can vary greatly depending on the size and location of the operation, recent statistics reveal the average cost of generator rental and fuel for gold mining is about 4,700 per month for a 20 kW unit and around 1,000 per month for fuel in USD. That said, high fuel prices can lead to total costs as high as 10,000 per month.
Gold mining costs continue rising in Q1'21. Costs in the gold mining industry increased for the second consecutive quarter in Q1'21, with the global average Allin Sustaining Cost (AISC) up by 5% qoq to US1,048/oz, reaching its highest level since Q2'13. This, combined with a 4% fall in the average quarterly gold price, resulted in a 14% ...

The primary operating costs of a crusher are parts and labour for maintenance, which can vary approximately twice as much as the power for the motor. Gyratory crushers generally cost less than 1500 per hour to run, while Jaw crushers cost less than 200, including electricity (Infomine, 2008). Rules of Thumb
A case study illustrating the optimization of a conventional gold ore grinding circuit is shown in the attached Table 3. Operating Modes of the Polycom HPGR in a Gold Plant. The grinding circuit applications of Polycom HPGR units for mining applications have been described previously by Patzelt (1987), Otte (1988), and Otte Patzelt (1991).

Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
Due to their significantly higher grades, refractory ores yield costs per ounce that are frequently lower than the average costs for conventional ores. Millhead grades of refractory deposits can be 86 percent higher; as a consequence, the operational costs per ounce of gold produced are approximately 19 percent lower in the case of refractory ...
