Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite

Abstract: Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation.

02-01-2012· With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

01-02-2005· The plant 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.

The recovery of iron from low-grade (31.6% Fe) Muro iron ore was investigated using reverse anionic flotation of quartz. Tests were performed to investigate the effect of pH, the effects of using distilled vs. tap water as the flotation medium and the effects of using cassava starch vs. dextrin for the depression of iron minerals.

Flotation circuits are often operated at a pH range of 75 to 115 The exact range at any given plant is optimized for the ore at that site Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite Particle Size The particle size to which the ore is ground ...

Nowadays, reverse flotation is the most commonly used route in iron ore flotation.

Abstract. The influence of pulp pH, dispersants, and auxiliary collectors on reverse flotation of carbonate-containing iron ores was explored. Interactions between iron ores and quartz were theoretically analyzed by flotation solution chemistry and DLVO theory.

Normally silica is floated using an amine as the flotation reagent. But "reverse" flotation using anionic collectors is also applicable to activated rock minerals (e.g., C2+ activation of silica) whereby the iron-bearing minerals are depressed. Much effort has been devoted to developing flotation processes for treating iron ores,
