Iron concentrate can be obtained from vanadium titanium bearing magnetite ore through beneficiation, which mainly recovers iron and vanadium resources through the process of blast-furnace ironmaking and converter vanadium extraction.
Our FLOTIGAM™ collectors are able to produce iron ore concentrate with low silica content by froth flotation, resulting in high purity concentrate, which is needed for steel production. Clariant's iron ore technical experts and flotation specialists can work with your technical teams to develop customized solutions for your specific needs.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an …
Making iron and steel from iron ore requires a long process of mining, crushing, separating, concentrating, mixing, agglomeration (sintering and …
An iron ore concentrate from the Iron Quadrangle from Minas Gerais (Brazil), Itabira region, has been selected for the study. With about 66% Fe, the ore is essentially composed of hematite with minor amounts of quartz as contaminant.
To effectively control the morphology of iron ore concentrate and obtain suitable pellet properties, it is critical to understand how magnetite concentrate morphology affects oxidation and sintering rates during pellet induration.
The final iron ore concentrate to charge the furnace must be converted into pellets in the Pelletizing process. In the pelletizing stage, after adding water and other additives such as soda and bentonite, etc., the process of making …
