Abstract

The disclosure provides a wet processing technology for a ferronickel material. The wet processing technology includes performing oxygen leaching processing on ferronickel powder to obtain a solution containing nickel sulfate and a solid phase containing ferric oxide, wherein the oxygen leaching processing includes: mixing sulfuric acid and the ferronickel powder to form a system to be leached, and adding an oxidant and an enhancer to the system to be leached to perform oxidation leaching to obtain ore pulp containing the nickel sulfate and the ferric oxide, the enhancer being a compound containing a SO2 group. The oxidant and the enhancer are added during oxygen leaching processing, iron in the ferronickel powder is oxidized into ferric oxide by the oxidant, so as to be separated from the solution in the form of precipitation, and nickel reacts with the sulfuric acid to form the nickel sulfate under the action of the enhancer. Consumption of the sulfuric acid in the wet processing technology of the disclosure is relatively low, and no obvious bubbles are generated in a reaction process, which indicates that no hydrogen is generated in the process, thus effectively solving the above safety problem. In addition, the iron is precipitated in the form of ferric oxide and therefore separated from the nickel, and the ferric oxide may be directly used as a ferric oxide product.
