Winning the Metal: Ore Mills of the West
Stamp mills would either ship the bullion product of free-milling ores, or it would ship a concentrate, the product of more complex ores, that would need further processing at a smelter. A variety of machines and techniques were developed to concentrate the crushed ore that came out of …
Strategic approach to mine-mill reconciliation
Metal accounting systems of mining and processing operations are coming under increasing scrutiny, primarily because of poor agreement between the estimates of mined metal and the quantity of metal actually produced by the concentrator, refiner or smelter. This scrutiny comes in the wake of scandals in the financial accounting world, which has …
A systemic approach to managing the Mine to Mill
Underpinning the mining process is a continuum of prediction, specifically of tonnes, grade and recovery from exploration to grade control, through short-term mine design, to mining and processing. The interdependence of one activity on the other is so strong that it can be difficult to partition the activities and determine where there are issues, if any. …
