Beneficiation of Iron Ores IspatGuru. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.
Figure 13.5. Mill sampling system by in-stream analyzer. The probe is installed in the slurry stream of feed (conditioner) and reject (tailing) for continuous sensing of metal grades and simultaneous digital process control of reagents.
The coal beneficiation facilities including a process description may be detailed. The proposal regarding future maintenance, or dismantling, of the structures of washeries may be given.
The steps to be taken for proper functioning of the slurry pond, handling of coal rejects and their utilization, periodic desilting, arrangement for water recirculation, measures to prevent water pollution from slurry ponds, arrangement for surplus water overflow, etc. shall be indicated in the mine closure plan. Reject dumps should be properly benched and graded on cessation of washery mining operations and the area should be reclaimed biologically. Similarly, slurry ponds should be dismantled and dewatered and the area reclaimed at the end of washery mining operations.
In the beneficiation of phosphate ores the tailings generated still carry significant phosphate content. The recovery has been difficult as the tailings carry a large proportion of clay minerals, magnesium oxide and iron carbonate mineral known as ankerite, an iron carbonate. Until recently, there was no suitable method for separating phosphate from such clayey wastes.
Progress has been made to recover some fraction of phosphate from these wastes. Separation of ankerite mineral has been attempted by magnetic separation with some success (Abdel-Khalek et al., 2001). The magnetic stream enriched with phosphate is further processed by flotation to separate magnesium oxide. A product containing 31–32 P2O5 by processing tailings with 20 P2O5 has been produced (Abdel-Khalek et al., 2001).

Over 95 of all acid grade fluorspar is processed by flotation through “Sub-A” (Fluorspar Type) Flotation machines. These machines, of the cell to cell type, are designed special for fluorspar with a high degree of flexibility essential for selectivity and multiple cleaning of concentrate. Middlings and clean tailings often must be completely isolated from the separate cleaning steps and diverted to the proper part in the milling circuit for most economical and efficient retreatment.
Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19 even on low grade feldspar ores. Dry recovery methods are economically limited to about 17 Al2O3.
Typical beneficiation processes include crushing, roasting, magnetic separation, flotation, and leaching. Second, additional processes such as smelting and alloying are used to produce the metal that is to be fabricated into parts that are eventually assembled into a product.

Description. The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens.

For example, a production line may be used to manufacture a range of vacuum cleaners, where the only difference between the models is the color of the plastic assembly and the attachments that are included in the final.
Involve the removal of seams followed by more or less controlled subsidence of the overlying strata. Raw coal may be sold as mined or may be processed in a beneficiation washing plant to remove noncombustible materials (up to 45 reduction in ash content) and inorganic sulfur (up to 25 reduction).
