The difference between a mineral and an ore is that minerals are naturally occurring compounds of metals that present along with other matter such as soil rocks sand and limestone. Whereas ores are the minerals from which the metal can be extracted profitably.
Chat Online· Gold processingGold processingMining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g. 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for
