Jan 02, 2012· The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such aspetroleum sulphonate,fatty acids and hydroxamates. In 1950s, the direct flotation route was integrated in plants, including Humboldt Mine (USA, 1954), Republic Mines, (USA, 1956), and Anshan Iron & Steel Corporation, (China, 1958).
Get PriceThe main objectiveof iron ore flotationis to upgrade the concentrate by removing silicates and/or phosphorus-containing minerals. The use of silicaflotationhas increased in recent decades. The trend will continue as more complexoreshave to be mined and higher-gradeiron oreconcentrates with fewer impurities are requested by the steel ...
Get PriceFeb 01, 2005· Theplant practice of iron ores flotation involves the conventional reverse cationic route, with ether amines employed as quartz collector and gelatinised corn starch used as iron oxides depressant. Options already incorporated in industrial operation, concerning the collector, include combining mono-amines with di-amines and partial substitution of amines by fuel oil.

Get PriceDescription. A low-grade iron ore from one of the largest Mexican deposits was investigated. Flotation was performed on samples with different particle size distribution to verify the influence of liberation and evaluate iron losses in case of a possible screening prior flotation. The results show that there is a considerable difference in the quality of the final product from flotation between the samples which …
