Mineral separation method for vanadium-titanium magnetite ores

The invention discloses a mineral separation method for vanadium-titanium magnetite ores. The mineral separation method comprises the following steps of: conveying raw vanadium-titanium magnetite ores to a primary grinding stage; conveying the crushed vanadium-titanium magnetite ores to a primary swirler for classification; conveying deposited sand of the primary swirler to a magnetic separator for magnetic separation, demagnetizing primary tail-ground refined ores subjected to magnetic separation, and returning to the primary grinding stage for grinding again, wherein the tail-ground tailings subjected to magnetic separation are final tailings; and sequentially performing primary rough magnetic separation, secondary grinding, secondary swirler classification, high-frequency fine screening classification, secondary magnetic separation, fine separation, sweeping, filtration and dehydration on overflowed ores of the primary swirler so as to obtain the vanadium-titanium magnetite ores and the final tailings. Compared with the prior art, the treatment capacity and the yield of a vanadium-titanium magnetite ore mineral separation system are improved, the raw ore machine time and the fine ore machine time are prolonged, and great economic benefit can be obtained.
