Nickel Hydroxide is a highly water insoluble crystalline Nickel source for uses compatible with higher (basic) pH environments. Hydroxide, the OH - anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most …

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).

A process for producing a purified nickel hydroxide precipitate from a nickel-containing leach solution with impurities including one or more of the following: manganese, copper, zinc, iron and/or cobalt, so that the purified nickel hydroxide is suitable for pelletization with iron-containing ores and/or stainless steel production, includes treating the leach solution with a base to form a ...

Conclusions Precipitation behaviours of nickel hydroxide from nickel laterite ore leaching are dependent on pH, temperature and the addition of seed. Increasing pH, temperature and the use of appropriate seed material enhance the precipitation of nickel hydroxide.

Nov 23, 2010· Nickel hydroxide usually occurs as green crystals that can be precipitated when aqueous alkali is added to a solution of a nickel (II) salt. It is insoluble in water but dissolves readily in acids and ammonium hydroxide. Nickel oxide is a powdery green solid that becomes yellow on heating.
