Typical Magnetite Processing Circuit Crushing HPGR 212 micron Coarse LIMS.Processing of Magnetite Iron Ores - Comparing Grinding Options Although the majority of current steel production is supported by iron ore sourced from high grade haemetite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.
Fig 1 A typical flow sheet of iron ore beneficiation plant. Some of the common methods techniques applicable for iron ore processing are described below. Crushing, grinding and screening technique. The purpose of grinding and regrinding is to reduce the ore to a size small enough to liberate and recover the valuable minerals.Iron ore is an important industrial source, is an iron oxide ore, a mineral aggregate containing iron elements or iron compounds that can be economically utilized, and there are many types of iron ore. Among them, the iron smelting products mainly include Magnetite, siderite, and hematite and so on. Iron exists in nature as a compound, and iron ore can be gradually selected after.
