Freeman W, Newell R, Quast K (2000) Effect of grinding media. and NaHS on copper recovery at Northparkes Mines. Miner Eng. 13(13):1395–1403. 27.
The addition of NaHS after grinding using mild steel rods increased the froth stability by increasing froth mineralisation, thus increasing the flotation kinetics of the copper minerals. When stainless steel grinding media was used, the copper flotation recovery was very high (>90 % in the rougher stage) without the addition of NaHS, so its use ...
Effect Of Grinding Media. Terms of energy requirements and steel consumption related to grinding media and liners spherical grinding media are predominantly used in final stages of ore grinding the spherical balls change shape through breakage and wear though this is universal in milling its contribution and effect on milling kinetics load behaviour and mill power
Flotation In Mining Copper And Gold Oxide Ore. offers 1,481 ball mill for grinding copper ore products. About 82% of these are mine mill, 2% are other fabrication services, and 1% are grinding equipment.
