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.

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.

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

Iron Ore Froth Flotation Floatability 1. Introduction During the processing of Iron Ore, unwanted ultra-fine material (typically < 150 µm) is generated and is an unavoidable consequence of the crushing process.

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.

Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.
