• Ore Treatment an overview ScienceDirect Topics

    Iron ore processing by Rio Tinto in the Pilbara region of Western Australia does not involve any chemical treatment. Flowsheets for the Brockman 2 and Paraburdoo processing plants are given in Figures 8.4 and 8.5 (Kinnel, 2013). The flowsheets are relatively simple. Dry processing involves up to three crushing circuits to produce lump and fines.

    Sep 01, 2020· Prendergast (1988) reported processing trials of oxidized PGE ores from the Great Dyke, Zimbabwe, by means of gravity concentration and flotation and the reported recoveries were far below 50%. Oberthür et al. (2013) stated that metallurgical test on oxidized ores from the Ngezi mine in Zimbabwe achieved Pt and Pd recoveries of only 15–30%.

    Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an
