Sorting method for high-chromium ilmenite

The invention provides a separation method for high-chromium ilmenite, and relates to the technical field of metallurgy and mineral processing. Specifically, the separation method comprises the following steps that firstly, the high-chromium ilmenite and a coal-based reducing agent are mixed to react, a reduction product obtained through the reaction is subjected to primary magnetic separation, and titanium concentrate and first tailings are obtained; secondly, the first tailings are subjected to secondary magnetic separation, and second concentrate is obtained; 3, oxidizing roasting is carried out on the second concentrate, third magnetic separation is carried out on the roasted product, and third tailings are obtained; fourthly, the third tailings are subjected to electric separation, and fourth concentrate is obtained; and 5, the fourth concentrate and a coal-based reducing agent are mixed for a reaction, a reduction product obtained through the reaction is subjected to fourth magnetic separation, and chro
