A basic principle of many processes for extracting copper and nickel from sulphide ores is to overlay the molten ore or matte with a lime-silica-iron oxide slag and blow with air or oxygen Some of the iron present in the ore oxidises and, as a result, partitions to the slag phase, while some of the sulphur is carried off as sulphur dioxide.
The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe From the X-ray diffraction analysis, the main phases present in the ore were pentlandite (494%), pyrrhotite (412%) and quartz (46%), Fig1 The ore which was supplied in lumpy form was subjected to crushing and grinding.
Extract maximum value with minimum environmental impact when processing sulfide nickel or We understand the intricate challenges and have the expertise and experience to design and optimize solutions to suit your specific ore type and - from complete concentrator plants to specific equipment.
The Wedgetail Field operations included the assessment of options for mining solid sulphide ores with subsequent third-party processing; drilling and geophysical surveys at a previously identified area of potential sulphide nickel mineralisation on the field’s flanks and in its deep horizons; and reinterpreting of the existing geological data.

1 1 Froth Flotation - Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a.
A lack of growth in nickel sulphide production, and a reliance on laterite nickel supply, has significant implications for the nickel market As sulphides tend to be lower cost than laterites, average costs will increase Sulphide ore can be upgraded, smelting is less.
About Nickel sulfide; Nickel sulfide weighs 566 gram per cubic centimeter or 5 660 kilogram per cubic meter, ie density of nickel sulfide is equal to 5 660 kg/m³; at 24°C (752°F or 29715K) at standard atmospheric pressureIn Imperial or US customary measurement system, the density is equal to 353342 pound per cubic foot [lb/ft³], or 327 ounce per cubic inch [oz/inch³].
Metallic nickel is primarily obtained from two ore types: nickel sulphide and nickeli-ferous laterite (oxide) or Global nickel resources averaging a minimum nickel grade of about 1% contain about 130 million tons of nickel, and the distribution between the nickel sulphides and nickel laterites is estimated to be approximately 40% and 60%, re.
Sulphide ore grades range from 015% to around 8% Ni, but 93 per cent of known deposits are in the range 02-2% Ni (Hoatson, 2006) Nickel-bearing lateritic ores, with average nickel content of 1-16%, are formed by tropical and sub-tropical surface weathering Table 3 summarises these.
Exploration and follow-up exploration of copper-nickel sulphide ores are underway at the Maslovskoye Field and deep horizons and flanks of the Oktyabrskoye and Talnakhskoye Fields pertaining to the Norilsk Industrial District Exploration of the Mokulaevskoye Field’s industrial limestone deposits has.
Business The top three nickel sulphide-bearing deposits in Canada Nickel is poised for growth this year as the Indonesian ore ban continues to prevent local miners from exporting raw minerals.
Copper-Nickel or Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed.
Jun 21, 2012· The nickel laterite challenge , Nickel occurs in essentially two ore types; magmatic sulphides and ('wet' or 'dry') laterit , of saleable 'intermediate' products such as mixed sulphide or.
Magmatic Nickel Sulphide Deposits The bulk of nickel mined today comes from either nickel laterite deposits, in deeply weathered terrains where nickel is released from the weathering of ultramafic rocks, or from nickel sulphide deposits which is our primary focus at Grasset.
Nickel is primarily extracted from the nickel sulfides pentlandite, pyrrhotite, and millerite, which contain about 1% nickel content, and the iron-containing lateritic ores limonite and garnierite, which contain about 4% nickel content Nickel ores are mined in 23 countries, while nickel.
komatiite-associated nickel sulfide (NiS) deposit of its type in the world Low-tenor ores typically range from 8 to 12 wt% nickel, and high-tenor ores range from 18 to 23 wt% nickel The Edwards lode represents the down-plunge continuation of the Otter-Juan ore shoot The Edwards lode is abnormal because its Ni tenor var.
Ores Containing Cobalt , substitute for transition metals in many minerals and chemical compounds and is commonly found in the place of iron and nickel as they share many similar chemical properti , An immiscible liquid sulphide phase is concentrated in magmas This phase preferentially collects and concentrates metallic elements such.
Successful searches for nickel-sulphide or Research by Dr Hill’s research team, on the Australian komatiite-associated ore deposits and their host rocks identified a continuum of proven and possible ore-bearing environments, which can be confidently placed into Hill’s flow-field model.
With nickel found in two radically different types of ore, it is not surprising that the mining methods differ Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stag.
