Under the condition of producing qualified nickel concentrate, the increase of nickelrecovery is limited in a bench test and commercial test by strengthening pulp dispersion and desliming.
The experiment results showed that the dosage of coke had the largest effect on the recovery of cobalt and nickel, but no obvious influence on the recovery of copper.
The results show that the existing technological flowsheet can well recover nickel, copper and cobalt while the precious metal recovery level remains to be improved.
