Beneficiation: Reference in the mining industry to the process of separating ore by crushing and other means into mineral and waste products: Billet: A semi-finished long product of up to 150 mm square cross-section with round corners. Billets can be continuously cast or hot rolled from either ingots or larger concast billets and blooms.
Mar 21, 2015 The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore i.e., an ore beneficiation process. The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.
