Cost of Producing Concentrates from Ore

2017-4-12  From the viewpoint of mineral economics, the ultimate and significant production cost is that per unit of metal produced rather than the cost per ton of ore treated. This viewpoint is natural to processors of ores whose final product is refined or unrefined metal, whether they be companies engaged solely in smelting, or integrated companies ...

Avoided energy cost of producing minerals: The case of ...

2019-11-1  This free concentration of minerals can be seen as an “avoided cost” with regard to mineral processing and refining. When high-ore-grade mines are depleted, as is currently happening , there is a reduction in this free bonus. This leads to extensive exergy consumption for extracting a similar quantity of metal from a lower-ore-grade mine.
