These mineralogical properties can affect the processing and beneficiation of iron ore. Occurrence: Iron ore can occur in various geological settings, including sedimentary, metamorphic, and igneous rocks.
In India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 1025 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000 ). The tailings contain silica in high percentage (4060 %, from various locations).

Abstract Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world's largest trilliondollarayear metal market and is the backbone of global infrastructure.
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through threestage crushing and thus segregated by screening into 1040 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has been ...
Ore processing is a chain of processing applications which treats run of mine to firstly highgrade concentrate (concentration of ores) and then to the pure mineral or metal. The refined ore is used in manufacturing equipment and machinery in numerous industries, or is for sale in industry, commerce and consumer industries.
Iron ore beneficiation is mainly a process of separating valuable minerals and iron minerals from ores to extract highquality iron ore. The iron ore process mainly includes crushing, grinding, washing, beneficiation, dewatering, etc. Magnetite Beneficiation: The main iron mineral contained in magnetite is iron tetroxide (Fe3O4).

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
Much of the remaining iron ore resources in Brazil consist of lowgrade itabirite ores. Accordingly, a typical beneficiation circuit includes a fourstaged crushing/screening plant, followed by grinding in a closedcircuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.

Six steps to process iron ore 1. Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
