These tend to be soluble polymers (such as starch) that selectively coat mineral surfaces and prevent collector from attaching. An example of this is in the “reverse flotation” of silica from iron ore, where the silica tailings are floated using a cationic collector at a pH of 8.5

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 ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.

FROTH FLOTATION “So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined.” The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.

froth-flotation process. Ground ore mixed with xanthates (salts esters of xanthic acid), dithiophosphates, or thionocarbamates. These make the ore surface hydrophobic. Ore then introduced into a water bath where air is bubbled through the suspension. Finely divided hydrophobic ore particles latch on to the air bubbles and travel to the surface

froth flotation of iron ores ppt
Principle of operation: Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from the desired mineral.

Intense aeration of the deflocculated and dispersed pulp is necessary for removal of the finely divided silica and iron silicates in the froth product. A 6-cell No. 24 Free-Flow Flotation Machine will effectively treat 35 to 40 LTPH of iron concentrates down to the desired limit, usually 4 to 6% SiO2. Loss of iron in the froth is low.

creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1.

pre-concentration of iron ore by gravity or magnetic methods. The flotation method commonly applied is the one based on cationic flotation of silica and silicates, that is, reverse flotation [5]. The reagents required for froth flotation are collectors, frothers and regulators, such as activators and depressants.
