Detoxification processes are used to reduce the concentrations of toxic constituents in tailings streams and process solutions, either by dilution, removal, or conversion to a less toxic chemical form (sometimes referred to as"destruction" or "degradation" in the case of toxic cyanide species). The objective is to produce an effluent that meets limits or guidelines that have been …

Grinding and Flotation Methods. For grinding test, 1500 g samples were ground for the suitable time period by a laboratory ball mill at 50 % solid. Then, the resulting pulp was transferred into a 5-L Denver-D12 flotation cell. After preparation of pulp, froth collection was regularly performed in separate containers.

Lumpy ore after semi-autogenous milling in Copper–Nickel ore processing at the Talnakh factory is studied. The lumpy ore is mainly presented by sizes −80+40 and −40+20 mm. The X-ray radiometric separation tests of the lumpy ore prove their efficiency in production of concentrate and tailings. The strength characteristics and the Bond work index of the …

A process for the flotation of nickel and copper sulphide minerals from talcose bearing ores comprising wet grinding the ore to produce an alkaline pulp thereof in a suitable state of subdivision for flotation wherein at least one alkaline reagent present is soda ash or ammonium hydroxide and the pH is within the range of from about 8 to 10.5 ...

Jul 28 2019 · Sulfide ores can be separated using froth flotation and hydrometallurgical or magnetic processes to create nickel matte and nickel oxide. These intermediate products which usually contain 40-70 nickel are then further processed often using the Sherritt-Gordon Process.

Alkaline Chlorine-Hypochlorite Oxidation: Chlorine was used for cyanide destruction in the early days of cyanidation in the late 1800s, because chlorine and its derivatives were readily available in the industry at that time.The method has been applied ever since in a variety of forms. The active reagent for chlorine oxidation of free and complexed cyanide is the …

Raglan now lies within Xstrata's nickel division, being operated by Société Minière Raglan du Quebec Ltée. The mine was originally designed to produce 130,000t/y of high grade nickel-copper concentrate containing 21,000t of nickel, 5,000t of copper and 200t of cobalt, plus precious metals. It is one of the world's lowest-cost nickel ...

The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of foam products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.

Application Of Flotation Process. It is widely used for copper, lead, zinc, nickel, molybdenum, gold and other non-ferrous metals, ferrous metals and non-metallic minerals roughing, concentration and flotation operations.
