Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).
The processing plant will process millions tonnes of nickel ore to produce millions tonnes of autoclave feed. The nickel/cobalt hydroxide is forecasted to be 103 thousands tonnes, containing 40 thousands tonnes of nickel metal and thousands tonnes of cobalt metal produced annually.
The nickel settles and the solution is pumped out to a holding tank. Since the solution still contains some nickel, it is reprocessed again to recover the remaining nickel. The nickel can then be removed through a cone bottomed tank or by a thickener/filter operation to yield the nickel powder.

Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (, associates with iron) and chalcophile (, associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:
Vale is the world's largest producer of nickel, one of the most versatile metals in existence. Hard and malleable, nickel resists corrosion and maintains its mechanical and physical properties even when subjected to extreme temperatures. Our highqualitynickelis also valued for its .
Coral Bay Nickel Corporation operates a Hydrometallurgical Processing Plant (HPP) in Rio Tuba, Bataraza, Palawan to produce nickel and cobalt sulfide from existing stockpiles of low grade nickel ores from the Rio Tuba nickel mine of Rio Tuba Nickel Mining Corporation.
Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide nickel Laterites make up 70% of the world's nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world's nickel.
copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of largescale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum (bauxite), phosphate, and uranium.
Nickel. Nickel is silverywhite. hard, malleable, and ductile metal. It is of the iron group and it takes on a high polish. It is a fairly good conductor of heat and electricity. In its familiar compounds nickel is bivalent, although it assumes other valences.
Ores with a high gibbsite content can be processed at 140°C, while böhmitic bauxites require temperatures between 200 and 280°C. The pressure is not important for the process as such, but is defined by the steam saturation pressure of the process. .
