  • A METHOD FOR ENRICHING NIOBIUM AND TITANIUM IN A MINERAL CONTAINING IRON, NIOBIUM AND TITANIUM AND A USE OF A NICKEL-CONTAINING SUBSTANCE
    Publication number: 20230416870
    Abstract: A method for enriching niobium and titanium in a mineral containing iron, niobium, and titanium, includes: reacting raw materials comprising 1 part by weight of a mineral containing iron, niobium, and titanium, 0.1-0.8 part by weight of a nickel-containing substance and 0.2-1 part by weight of carbon at 800-1500° C. to obtain a nickel-iron alloy and a niobium-titanium rich slag, where an amount of the mineral containing iron, niobium, and titanium is counted in terms of iron element, and an amount of the nickel-containing substance is counted in terms of nickel element. The nickel-containing substance is one or more selected from the group consisting of oxides of nickel and nickel minerals.
