In present work, a kinetic study on selective leaching of low-sulfur Ni-Cu matte at atmospheric pressure was conducted.

Jilin nickel Corporation's nickel smelter has been producing nickelic matte by the process of electric smelting and converter blowing.

This magnetic matte was obtained from high grade Ni-Cu matte by floatation-magnetic separation, which enriched in precious metals, and mainly contained Ni alloys and a small quantity of sulfides.
