Nickel Oxide (Green) – Welcome to Chivine

Nickel Oxide (Green), NiO or Ni(ii) oxide, is an inorganic metal oxide that is used in the production of nickel alloys, salts, catalysts, fuel cells and other chemicals. Ceramics Like nickel oxide- black, green nickel oxide is also a ceramic glaze colorant and color softener. It can produce colors ranging from green, blue, grey, brown to tan depending on the other materials in the glaze.

Sulfate Formation and Decomposition of Nickel

2011-1-5  Heating Nickel Sulfide Concentrates in Air. Nickel sulfide concentrates react with air during heating, leading to mass changes and to the evolution of SO 2 in the off gas. Using the TGA combined with off-gas analysis, these phenomena were quantified. An example of the results obtained is given in Figure 3. After heating in air at 15 K/min, the oxidation of Strathcona, VBN, and A2 concentrates

Autoclave processing of low grade copper-nickel

1995-10-1  A chemical-mineralogical investigation of the behaviour of ore and rock-forming minerals of low grade nickel-bearing concentrates in sulphuric acid solutions has been carried out. A preliminary acidic treatment of the concentrates was carried out in an attempt to dissolve silicates and oxides and prepare the material surface for autoclave leaching.

Nickel sulphide concentrate processing via low

This study aims to identify the interaction products of sulphide nickel concentrate components with sodium chloride at temperatures of 400–450 °C. Thermodynamic studies have demonstrated that nickel sulphates, chlorides, and oxides are the probable nickel-containing products of the interaction between nickel sulphide and sodium chloride in the presence of oxygen.
