Nickel Ore an overview ScienceDirect Topics
Ore grade has a direct effect on mine investment costs expressed in US$ per annual tonne of nickel. Consider two identical ore bodies, one containing 1.25% Ni ore and the other containing 2.5% Ni ore. Achievement of an identical annual production of nickel in ferronickel requires that the 1.25% Ni ore be mined at twice the rate of the 2.5% Ni ore. This, in turn, requires about twice as much

12/04/2017 Costs per pound of lead and zinc (not including smelting) are given for seven companies in table 32 of Bulletin 381. The following brief discussion and tables giving production and overhead exists per ton are presented, therefore, with due recognition of the fact that the ultimate economy of a mining enterprise depends upon tho cost per unit of metal and the net value of the metals produced.
Nickel Sulfide Versus Laterite : The Hard Sustainability
available to examine in detail the differences in the environmental costs of nickel sulfide versus laterite. The paper compiles and analyses a range of data, showing the higher energy costs of laterite projects, but also the critical importance that energy sources can have on overall environmental costs. Given that the world is continuing to demand nickel, and most uses are somewhat
Nickel processing Extraction and refining Britannica
Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag. This is done in a rotating converter of the type used in copper production. The slag is
Why heap leach nickel laterites?
electric furnace smelting followed by either refining to produce a ferronickel product or converting to a low iron-containing matte. Outside of China where there are 2 atmospheric leach project and a small heap leach the only operational hydrometallurgical processes are High Pressure Acid Leaching (HPAL). 2.2. Pyrometallurgical For all pyrometallurgical nickel laterite operations the ore must
