Derrick Iron ore, grinding circuit classification, silica reduction

Derrick screens have been used in iron ore since the 1950’s processing all types of iron ore. From removing fine impurities in Direct Shipping Ore sinter products to scalping relatively coarse (+53 to 75 µm) middlings and size control in pellet concentrates. Some of the greatest benefits of fine screening have been achieved by replacingHematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.Developments in iron ore comminution and classification
