Abstract: Aiming at the problem of heavy losses of iron tailings metals in a dressing plant of Shandong province,systematic recovery process flow research was conducted. Ultimately,the recovery process flow of strong magnetic separation- reverse flotation was determined and iron concentrate with yield rate of 7.94%,iron grade of 52.17%,recovery rate of 37.23% was obtained. The comprehensive iron grade of tailings discarding was 7.59%,economic benefit was remarkable.
