Flotation Of Ni Sulphides China Platre Fabrication Chapter 16 Flotation Of Nickel And Nickel Copper Ores Handbook of Flotation Reagents Chemistry Theory and Practice Flotation of Sulfide Ores Addressed to the researchers and plant metallurgists who employ flotation reagents this text examines the theoretical aspects of flotation reagents as It was found that the nickel sulphides responded to flotation at pH 9 with PAX and TETA additions and that maximum grades of between 6 to 8% were achieved with the average cumulative grade of the nickel concentrates having values of between 4 and 5 wt% nickel Cumulative recoveries were low, with values between 50% and 60% on a sulphide basis, which corresponded to a 35–45% recovery on a total nickel Selective sulphidation and flotation of nickel from a Developments in Flotation Flotation of Nickel Sul\de Minerals Collectorless Wotation It is known that chalcopyrite and pyrrhotite can be Soated without collectors at electrode potentials of #400 mV and #50 mV respectively, and pyrite does not Soat even at #700 mV The underlying mechanism causing hydrophobicity, although obscure, is attributed to surNICKEL AND COBALT ORES: FLOTATION 911 Metallurgist At Norilsk copper sulphides have been floated after depressing iron and nickel sulphides using steaming (Perepechin et al, 1975) As is known, the floatability of sulphides is stronger at slightly acid pH This has been applied especially with Finnish oresSome factors that affect beneficiation of sulphide (2007) Oxidation of Complex NiCu Sulphide Ores and its Implication for Flotation Practice Canadian Metallurgical Quarterly: Vol 46, No 3, pp 279284Oxidation of Complex NiCu Sulphide Ores and its
