METHOD FOR PRODUCING NICKEL CONTAINING INDURATED CHROMITE PELLETS, METHOD FOR PRODUCING FERROCHROME NICKEL ALLOY AND INDURATED CHROMITE PELLET

Described is a method for producing nickel containing indurated chromite pellets. The method comprises providing a ground mixture containing iron and chromium containing material and optionally carbon and optionally additives;providing nickel bearing material comprising precipitated nickel compounds from a process for hydrometallurgical refining of nickel bearing raw material, binding agent, and optionally fluxing agent;mixing nickel bearing material, binding agent and optionally fluxing agent into the ground mixture to produce an agglomerating mixture;agglomerating the agglomerating mixture to produce green pellets;and indurating the green pellets to produce indurated chromite pellets. The method comprises heat-treating the nickel bearing material prior mixing the nickel bearing material into the ground mixture to remove sulfur, water, possible carbonates and volatiles from the nickel bearing material and to produce nickel oxides in the nickel bearing material.
