ABSTRACT:
The method for nickel concentration processing, which is low cost, simple and convenient, as well as having low environmental load, which is capable of enhancing nickel content of a saprolite ore with low nickel content, which was not conventionally used effectively as a raw material of ferronickel smelting due to having low nickel content, to a level to be utilized economically as a raw material of ferronickel smelting.
