Nickel Simple English Wikipedia, the free encyclopedia

Nickel was found when a coppercoloured ore did not make copper metal. Later it was found out that the ore was actually a nickel containing ore. Nickel was isolated as a metal in 1751. At first, the copper colored nickel ore was the only source. Later, it was made as a

Nickel Chemistry

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.

Selective leaching of nickel from mixed nickel cobalt

Nickel can be recovered from solution as a final product, for example, as metal or a compound such as nickel hydroxide or sulphate. The leach residue, a mixture of cobalt oxyhydroxide and manganese oxyhydroxide, may be treated by methods described by Chong et

Nickel Oxyhydroxide Nanopowder AMERICAN ELEMENTS

Nickel was first discovered by Alex Constedt in 1751. The nickel atom has a radius of 124 pm and a Van der Waals radius of 184 pm. In its elemental form, nickel has a lustrous metallic silver appearance. Nickel is a hard and ductile transition metal that is considered corrosionresistant because of

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. SEM and particle distribution analyses of the precipitate shows that nickel

If a red precipitate forms, the ore contains nickel. If it just gets a little red, than it does not contain nickel. If the ore contains a lot of copper, then use sodium hydroxide instead of ammonium hydroxide solution to avoid formation of the blue complex. Summary Ore powder + sodium hypochlorite solution + hydrochloric acid
