Abstract: The present invention provides a method of separating nickel bearing sulphides from mined ores or concentrates of mined ores that contain talc particles is disclosed. The method comprises adjusting the Eh of a slurry of mined ores or concentrates of mined ores and making particles of nickel bearing sulphides less hydrophobic than talc particles and floating the nickel bearing sulphide particles from the slurry.
Abstract translation: 本发明提供一种分离含镍硫化物的方法，该方法包括含有滑石颗粒的矿石矿石或矿石的浓缩物。 该方法包括调整矿石矿石或矿石浓缩物的浆料的Eh，并使含镍硫化物的颗粒比滑石颗粒疏水性更小，并将含镍硫化物颗粒从浆料中浮起。

Abstract: A method of separating nickel bearing sulphides from mined ores or concentrates of mined ores that contain talc is disclosed. The method comprises treating a slurry of mined ores or concentrates of mined ores in at least one flotation stage and in at least one cleaner circuit. The method further comprises sequenced re-grinding, as described herein, of particles in the slurry.

Abstract: A continuous flotation process and apparatus for iron-containing sulphides in ores and concentrates of ores are disclosed. The process includes adjusting the pH of an aqueous pulp of the ores or concentrates of the ores to be in the range of 6.5-8.5 and thereafter adding a reducing agent to modify an iron hydroxide film on the surface of iron-containing sulphides in the ores or ore concentrates to enable adsorption of a collector onto iron-containing sulphides. The process also includes adding the collector to the pulp prior to, during, or after adding the reducing agent. The process also includes aerating the pulp to increase the pulp potential to a level sufficient to allow collector adsorption onto the iron-containing sulphides and thereafter bubbling gas through the pulp and subjecting the aqueous pulp to froth flotation to produce a froth containing said sulphide containing minerals.
Abstract translation: 公开了矿石和矿石浓缩物中含铁硫化物的连续浮选方法和装置。 该方法包括将矿石的矿浆或浓缩物的水泥浆的pH调节在6.5-8.5的范围内，然后加入还原剂以改性矿石中含铁硫化物表面上的氢氧化铁膜 或矿石浓缩物以使集电体能吸附在含铁硫化物上。 该方法还包括在添加还原剂之前，期间或之后将收集器加入到纸浆中。 该方法还包括充气纸浆以将纸浆潜力提高到足以允许收集器吸附到含铁硫化物上的水平，然后鼓泡气体通过纸浆并使水浆料浮泡以产生含有所述含硫化物矿物的泡沫 。
