Recently, the grade of iron ore deposits has deteriorated and further development of low grade deposits is desired. Presently, the most effective and often followed route taken to utilize such deposits is the provision of beneficiation plants for upgrading iron ore and pelletizing plants for agglomerating. Kobe Steel has much experience in constructing …
Conventional beneficiation processes such as flotation, electrostatic and magnetic separation, gravity methods and flocculation–dispersion using chemical reagents to treat the finer iron ore resources often prove to be inefficient, energy-intensive, costly, and environmentally-toxic.

Chromite Beneficiation Process. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed …
Two or more of these processes together (either concurrently or at different times) form mineral deposits. Certain scarce constituents of magma may become concentrated into bodies of sufficient size and constitute valuable mineral deposits. Magmatic ore deposits are characterized by their close relationship with intermediate- or …
Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is …
Graphite ore is mostly beneficiated using flotation separation techniques. The increasing demand for high-grade graphite products with up to 99.99% carbon has resulted in the development of various approaches to remove …
The beneficiation process can be defined as a treatment process of ore which results in a more concentrated form of the product. It is often used in the preparation of iron ore for smelting. This is an essential process as it helps improve the yield from a deposit of ore, thereby increasing the potential profits that can be obtained from the ...
The most widely used beneficiation techniques are flotation, direct carbonation, electrostatic up-gradation, calcination, and leaching/bioleaching. Bioleaching has environmental benefits and electrostatic up-gradation can achieve the highest quartz removal efficiency, although this is an energy-intensive process.
Depending upon the origin and mineralogical characteristics of the ore, the beneficiation methods vary from simple crushing and screening to complex concentration processes.
This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation. Emphasis is placed on different processes developed in identifying and solving critical plant problems.

This is carried out by the processes of beneficiation of the iron ore. Beneficiation of the ore is the process where ore is reduced in size and gangue is separated from the ore. Since each of the iron ore deposit has a unique mineralogy, the beneficiation process is specific to each deposit.
Any beneficiation process, which can effectively reduce the silica content of bauxite (mainly in reactive form such as kaolinite) is given the first priority in the metallurgical industry. Second priority is given to beneficiation methods for the reduction of iron content (e.g. goethite), which mainly causes settling issues and higher ore …
