In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.

At a time when the world demand for copper and nickel is escalating rapidly, a new metallurgical process is set to render the traditional smelting/refining route for these base metals redundant.
Nickel ( / ˈ n ɪ k əl / NI-kəl) is a chemical element with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile.Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can ...
Flotation definition is - the act, process, or state of floating. How to use flotation in a sentence.
Jun 10, 2016· Since flotation relies on selective adsorption of collectors on the surfaces of specific minerals, the lack of concentrated nickel at the mineral surface, or the concentration of nickel in only one phase and the presence of phases barren in nickel, can compromise the recovery of a …

Nickel sulfide ores are concentrated by the flotation process flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents.
nickel in these ores while containing over 75 per cent of the sulphur. Therefore, efforts to reduce sulphur dioxide emissions from the smelting process have included the rejection of pyrrhotite in the milling stage as an alternative means of treatment. In the flotation process, a number of reagents are seen as a means ofdepressing pyrrhotite.

2. 2. Flotation Procedure All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about
