Froth Flotation of Iron Ores sapub

02/01/2012· The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum 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).

Beneficiation of iron ore by flotation — Review of

01/04/1983· INTRODUCTION Research on the flotation of iron ore, on either a bench or a pilot-plant scale, started towards 1931 (Crabtree and Vincent, 1962). It was mostly confined to ores containing siliceous gangue, which appears to be the most abundant type in the world and the reserves of which, when based on a minimum tenor of 30 to 35% iron, amounts to a respectable quantity of milliards of

Iron ore Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and
