iron oxide ore beneficiation

Ore Beneficiation an overview ScienceDirect Topics

Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation (e.g., removal of alkalis, silica, clays, phosphorous, and alumina). Because the presence of phosphorous in the iron ore promotes bacterial growth (as an energy source), iron oxide particles having higher phosphorous contents were seen to be colonized by

The importance of mineralogy and petrology on the

The efficiency of any iron ore value-adding operation is closely associated with detailed knowledge of the mineralogy, especially in the processing of lower grade and complex ores. There are a number of physico-chemical properties of iron oxide mineral phases (eg goethite, hematite and magnetite) that can be prudently exploited to enhance their processing efficiency.

Beneficiation of iron ore Kennecott Corporation

U.S. Pat. No. 3,779,380 to Bishop describes ore beneficiation and particularly froth flotation applied to iron ore. The beneficiation process described enables direct flotation of the iron oxide. This process, however, is not as efficient when dealing with fine grained ores as is the present process.

Process for beneficiating a titaniferous ore and

The beneficiation of titaniferous ores by the chloride process produces iron chlorides. In this method of beneficiation, the ore mixed with carbon is reacted with chlorine at a temperature of 1,075° to 1,425°K. The iron oxide component in the ore is converted to vaporized iron chlorides.

US4206878A Beneficiation of iron ore Google Patents

Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the
