what is nickel ?
australia is the world’s third largest nickel producer, after canada and russia. most of australia’s nickel production is exported to europe, japan and the united states.
nickel is usually with cobalt or copper in lateritic nickel mines ore copper-nickel mine. about 65% of nickel is used to manufacture stainless steel. around 20% is used in other steel and non-ferrous alloys, often for specialized industrial, aerospace and military applications. about 9% is used in plating, while 6% in used in other applications, including coins and a variety of nickel chemicals.
india nickel crusher
the nickel crusher is widely used in nickel processing plant. sbm is a major nickel crusher manufacturer in china, our nickel crusher is from primary crushing, secondary crushing to fineness crushing. the common nickel crusher are heavy duty jaw crusher, small jaw crusher, impact crusher, spring cone crusher, cs series cone crusher, single cylinder cone crusher, hp hydraulic cone crusher and so on.
the crushing capacity of the nickel crusher can be up to 1000 tph, the final grain size of the crushed nickel ore can be down to 2mm in diameter.
india nickel mill
nickel mill is the major nickel milling machine to grind the crushed nickel ore. sbm can design and manufacture many types of nickel mills for nickel grinding. the common nickel mills are: ball mill, raymond mill, mtm trapezium mill, mtw trapezium mill, ultrafine mill etc. and the ball mill is the most widely used nickel mill to grind the nickel mill.
the ore is crushed to -5 inches in primary cone crushers, then reduced to -1/2″ in short head cone crushers. the ore is then ground to -100 mesh in ball mills. using wet magnetic separators the magnetic ore is separated and further reduced to -200 mesh in a ball mill. classification is accomplished with screens and cyclones. the pyrrhotite is then sent to froth flotation cells, and produces a 3% nickel concentrate.
india nickel mining process: crushing, milling
india nickel ore is usually mined from underground mine and some in open pit mine. the run-of-mine nickel ore will be sent to processing plant which includes crushing process, washing process, grinding process, concentration process.
firstly, the nickel ore mined will be conveyed to a stock bin before crushing and grinding. the nickel crushing and grinding plant can handle harder nickel ore as well as increasing the plant throughput.
the outflow from the mill enters a vibrating screen and the oversize is directed to a cs series cone crusher before being returned to the mill. screen undersize enters a ball mill/cyclone circuit before entering the flotation plant rougher cells.
after crushing and grinding process, the nickel ore will be conveyed to flotation plant. them the nickel ore will be sent to nickel smelter or nickel refinery.
india nickel ore concentration
after mining, the sulphide nickel ores are transported to a concentrator to upgrade their nickel content. the ores are first crushed and ground, liberating the sulphide minerals from worthless rock, or gangue. the sulphide minerals are then separated from the gangue, by flotation, and dried.
nickel ores grade about 3% ni content and the concentrates produced after treatment in the concentrator grade around 11% ni. concentrates produced at all three centres are transported to the kalgoorlie smelter for further processing.
the extraction of nickel from lateritic ore containing 0.8 to 1% ni, is complex with a number of process options available. the ore is subjected to high temperature pressure acid leaching followed by solvent extraction to yield nickel metal.
currently, heap-leaching operations are plagued by poor permeability of the heap, which leads to uneven distribution of the leaching solution, unleached zones in the heap, and low metal recovery. this poor permeability is caused by excessive amounts of fine particles clogging the spaces between larger ore particles. by agglomerating ores, individual ore particles will be held together in coarse, porous masses with the use of a binder. in addition to benefits for heap leaching, agglomeration is a critical factor in the success of the iron ore industry. this process requires the formation of strong agglomerates of coal, iron oxide, and flux without heat treatment, and at a minimal cost.
unfortunately, there are no known agglomeration binders that will work satisfactorily in the acidic environment encountered in many heap-leaching operations, and few binders that will produce high strengths without sintering. alkaline binders, for instance, are destroyed by acid attack, and are thus completely unsuitable for use in acidic leaching heaps. other binders are synthetic polymer compounds, but many of these binders also perform poorly in acidic environments. in most cases their synthesis costs are so high that they are impractical. as a result, operators of acidic heap-leach facilities cannot take full advantage of the agglomeration technique.
because of problems with effectiveness or cost, all binders that have been evaluated to date for use in acidic heap leaching have either performed poorly, or proved to be too expensive for commercial use. furthermore, mixing problems in all types of heap leaching operations has led to significantly more binder usage than necessary. the large quantity of ore that must be handled in heap-leaching operations requires that the binder must be kept to low dosages to be economical.
researchers will select the binders to be studied in this project based on theoretical considerations, with particular emphasis on low-cost reagents or industrial wastes/ byproducts that are expected to be particularly acid-resistant. the use of advanced compressive shear mixing technology will further reduce binder cost by ensuring that the binder is used with the greatest possible efficiency. michigan technological university, along with their project partners, will focus on developing a more broadly usable binder and a more efficient binder/ore mixing method that will benefit all heap-leaching operations that use agglomeration. the project will improve energy efficiency by increasing metal recovery during heap leaching, reducing the quantity of ore that must be handled and prepared to produce a given amount of metal.
another result of the project will be the decreased land area required for leaching pads due to the increased processing efficiency, which not only reduces cost, but also simplifies design to prevent spills and groundwater contamination. boosting the use of heap leaching will also generate lower emissions than are currently generated by conventional smelting techniques. the binders developed are expected to benefit the agglomeration of feed pellets for use in the iron nugget process, which will make it possible to implement this process as a high-efficiency, environmentally-sound replacement for blast furnace technology.
hematite deposits are mainly sedimentary in origin, rarer than magnetite bearing bifs or other rocks which form its main source or protolith rock. research and utilization of low grade iron ore plays an important role in the whole beneficiation process. the main beneficiation process includes gravity separation, flotation, strong magnetic beneficiation or mix several beneficiation process, and magnetization roasting and then weak magnetic separation.
