  • Gold Processing Mining And Concentrating Britannica

    Mining 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 extraction by cyanidation see below.

  • Ore Minerals What Are Ore Minerals Geology Page

    Nov 04 2019 The ore quality and density of a rock or metal ore as well as its occurrence type can directly affect the ore mining costs. It is therefore necessary to weigh the extraction cost against the metal value contained in the rock to determine which ore can be processed and which ore is too low a grade to be worth mining.

  • Factors Influencing Stope Hanging Wall Stability And Ore

    Oct 18 2019 Ore dilution contamination of ore by waste rock is a major concern when mining steeply dipping narrow-vein deposits. Dilution leads to the mixing of ore with barren waste or minerals below the cut-off grade during the mining process Jang et al. 2015 Clark 1998 Wright 1983 which lowers the mill recovery i.e. from lower feed ore grade and effective capacity as the mine life increases.
