Extraction of nickel . main ore is pentlandite nickel is extracted from ores through the mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. it is placed with hydrogen and carbon monoxide gases at 122 degrees fahrenheit, which converts it to impure nickel. get in touch gtgt

Nickel is the fifthmost common element on earth and is currently mined in more than 25 countries. nickelcontaining ore bodies require a variety of techniques to extract the nickel depending on the oretype laterites or sulphides being the predominant ores that nickel is extracted from.

A process for the extraction of metal from an ore or concentrate which contains nickel andor cobalt values and other metals, comprises subjecting the ore or concentrate to acid leaching under pressure at ph2 to obtain a liquor containing nickel andor cobalt values, subjecting the liquor to a first precipitation stage at ph of about 5 to 6 to produce a solid containing non nickel and non ...

Nickel is obtained from two main types of deposits from the mineral garnierite nisilicate in nickelrich laterite formed by weathering of ultramafic rocks in tropical climates. it also is mined from nisulfide concentrations, mainly from pentlandite in igneous mafic rocks.
