Beneficiation

Peter H. Woods, in Uranium for Nuclear Power, 2016 Ore beneficiation (including ablation, radiometric, and gravimetric sorting). Ore beneficiation refers to the selection and collection of highergrade ore fragments or rejection of lowergrade fragments from ROM ore. The upgraded ore will have a higher grade, and therefore require a smallerscale processing plant, perhaps .

PHASES OF A MINING PROJECT

The beneficiation process generates highvolume waste called 'tailings,' the residue of an ore that remains after it has been milled and the desired metals have been extracted (, with cyanide (gold) or sulfuric acid (copper)). If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then
