Sustainable Ore Transportation
Transporting run off mine and verburden/gangue is an area of focus as it accounts for more than half of the operating cost. Depleting grades have further aggregated the operation scenario, which in turn, translate to added hauling distance. As the existing method would incur additional expenses, an alternate solution is required.
Mining crushing grinding costs
A good rule of thumb is that an integrated mining crushing-grinding plant will have capex costs of $20/Tpa of capacity and consume 20kWh of energy per ton, while total full-cycle costs will run close to $10/ton of ore that is processed. (Numbers can be stress-tested in the 'model' tab). Our capex estimates are informed by evaluating a dozen ...
