The smelting process comprises the carbonaceous reduction of ilmenite to produce titania slag with a TiO2 content of 86, and iron with a carbon content of 2.5. In the Ti slag production process, the iron oxides are reduced to metallic iron, thereby producing a TiO2-rich slag and high purity iron.Chat Online
Calcium carbide is also called calcium acetylide, ... the produced carbide product will contain around 80 of the calcium carbide. Also, carbide is further crushed to produce small lumps that can range up to a maximum of 50 mm, and the impurities are concentrated in the finer fractions.

Jan 01, 2016 Gyratory crushers can accept 810 moisture in operation, but the fine content should be preferably less than 10. The crushing action in gyratory crushers is regarded as rings or helics spirals of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher.
MANGANESE ORE. Manganese is often used by the steel industry in deoxidizing and desulfurizing additives and as an alloying constituent. It can improve the rolling and forging qualities, as well as the strength, toughness, stiffness, hardness, wear resistance, and hardenability of steels. For example, steel containing 8-15 manganese can have a high tensile strength of up to 863 MPa, and steel with 12 or more manganese
In comparison, rotary sorters are in a way an improvement from spiral separators. Rotary sorters work best if you want flexibility for fine, precise tuning using a VFD Drive. They need power to operate, but they reduce a lot of load off other machines.
