SOUTH AFRICAN JOURNAL OF SCIE!o1CE, Vol. XXXI, 210-221,

Gravity concentration alone is not able to effect a recovery of much more than half the values in the sulphide ore and still less in the oxide or outcrop zone. Consequently gravity concentration has to be supplemented by flotation and a description of the procedure furnished by the

Ore - Wikipedia

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
