K inetics of acid-oxygen leaching of low-sulfur Ni-Cu matte at atmospheric pressure
A study of the leaching of low-sulfur Ni-Cu matte in acid-oxygen (CuSO4-H2so4-O2)solution at atmospheric pressure was described in present work .This matte was obtained from high grade Ni-Cu matte by magnetic separation ,which mainly contained Ni-Cu alloy and small quantity sulfides .The effects of variations in temperature ,agitation,oxygen flow rate ,particle size,acid concentration and concentration of copper ion were all studied.It was found that the matte particles were leached by shrinking core mechanism and electrochemical in natural .At a temperature range of 30-60℃,the surface reaction was rate-limiting step,with an apparent activation energy of 41.9 kj.mol-1.But at higher temperature(70-85℃),the rate process was controlled by diffusion through the product layer,with an apparent activation energr of 7.3 kj-mol-1.
