Flotation behavior of nickel sulfide ore in a cyclonic flotation column 775 In the flotation system, the density of mineralized bubbles (ρm) is much smaller than that of the fluid (ρ), and generally speaking, the density of particles (ρp) that cannot adhere to bubbles is much higher than that of the fluid (ρ).
The project began in early 2007 and was commissioned in November 2008.The plant was initially designed to process high Cu-low Zn ores (with Cu to Zn ratio 5:1) to produce marketable copper concentrate only.
For flotation separation of copper/nickel minerals, respectively.The Cu/Ni bulk flotation used 1kg ore to obtain a Cu/Ni bulk concentrates.After wet grinding, the desired amounts of reagents were added to the slurry while agitating at about 1900 rpm andthe slurry was conditioned for 6 min.
Hydrometallurgical processing of nickel laterites (limonites or saprolites) requires acidic conditions to dissolve the nickel within the laterite ore.This acidic solution is neutralized in several steps using lime, precipitating the dissolved element impurities from solution and recovering valuable base metals (Ni, Co, Cu) as precipitate products.
In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder.Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel.Smelting processes the concentrate further, creating nickel-rich matte, while impurities are removed as slag.

Ni is extracted from it by four processes-(i) Condensation: by oil-froth floatation process.(ii) Roasting (iii) Smelting & Bessemarization: A mixture of NiS, CoS & CuS is obtained, which is called “Nickel Matt” that contains- 55% Ni.Ni is collected by Mond or Orford’s process.
Nickel is commonly present in two principal ore types – sulfide or laterite ores.Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).
