Insights into Ferric Leaching of Low Grade Metal MDPI Ideally these low grade ores are processed to maximise metal recovery, leaving a waste rock with reduced environmental impact. Where waste rock is dumped without the recovery of the low concentration metals, understanding of natural leaching within the dump is equally as important for ensuring minimal environmental impact [ 1 ].

Insights into Ferric Leaching of Low Grade Metal MDPI The distribution of the metal bearing mineral grains within a particulate ore prepared for leaching, and the impact of this spatial heterogeneity on overall extraction efficiency is of key importance to a mining industry that must continuously target ever reducing grades and more complex ore bodies. If accessibility and recovery of the target minerals is to be improved, a more detailed

Ore The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
