Iron ore beneficiation: an overview
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …

Sink and Float Separation Process
Sink-Float Tests are classed as bulk or selective separations. A bulk test gives two products, first, the lighter minerals with a gravity less than 2.8 to 3.3 and, second, minerals having a gravity heavier than 2.8 to 3.3. The separation depends on the gravity of the media used. The heavy media generally used are as follows:

The Recovery and Concentration of Spodumene Using Dense Media Separation
In coming years, global lithium production is expected to increase as the result of widespread electric vehicle adoption. To meet the expected increase in demand, lithium must be sourced from both brine and hard-rock deposits. Heavy liquid separation (HLS) and dense media separation (DMS) tests were conducted on the pegmatites …

Non-magnetic physical separation of hematitic/goethitic iron ore
Another notable difference is that while coal DMS can use cheaper ground magnetite particles (density roughly 5.0–5.1 g/cc) to produce separation media with RDs of up to 2.0, the higher separation densities required in iron ore beneficiation necessitate the use of more expensive FeSi of well-controlled particle shape and size distribution as ...

Ferrosilicon Powder
The use of ferrosilicon powder has risen with the increasing employment of heavy media separation for ores, particularly in the separation of iron ores. In the separation of lead and zinc ores, ferrosilicon is a foreign body and the use of galena as a heavy medium would seem indicated; yet ferrosilicon has largely replaced galena for …

Dense Medium Separation (DMS)
The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required.
