Iron is the world’s most commonly used metal – steel, of which iron ore is the key ingredient, represents almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications.
Iron-rich rocks are common worldwide, but ore-grade commercial mining operations are dominated by the countries listed in the table aside. The major constraint to economics for iron ore deposits is not necessarily the grade or size of the deposits, because it is not particularly hard to geologically prove enough tonnage of the rocks exist. The main constraint is the position of the iron ore relative to market, the cost of rail infrastructure to get it to market and the energy cost required to do so.
Iron ore refers to the ore containing iron or iron compound, which is one of the most important raw materials in production of steel. There are many large-scale iron ore area which have high value of exploitation in Australia, Brazil, India, Canada, USA, Ukraine, Liberia and other countries. Main iron ores are magnetite, hematite, limonite, iron silicate ore, iron silicate mineral, etc. The most commonly used crushers in iron ore mining industry are jaw crusher, impact crusher, hammer crusher and high-efficient iron ore fine crushers, etc. In iron ore mining, customers usually choose a complete iron ore crushing production line for higher efficiency. At present, the most popular iron ore production line consists of two jaw crushers. After crushing, the material will be sent for the magnetic separation, and then into the ball mill for grinding.
zenith Machinery Company produces several series iron ore crusher, of which cone crusher and mobile crusher fits for processing this ore best.
Iron ore cone crusher is one of the most high efficiency iron ore crusher. Comparing with other iron crusher, iron ore cone crusher with high-efficiency has excellencies for iron ore crushing, high productions and low maintenance. The long force arm designed into the cone provides greater iron ore crushing force.
Iron ore mobile crusher is developed according to novel series iron ore crushing equipment’s design idea, which expands the concept field of coarse crushing and fine crushing. zenith iron mobile crusher is designed based on the conception of fully adapting various iron crushing condition, eliminating obstacles caused by location, environment, foundation configuration, consequently providing simple, efficient, low-cost crushing equipment. Our iron ore mobile crusher includes cone crusher series mobile crusher, impact crusher series mobile crusher, jaw crusher series mobile crusher and crawler type mobile crusher. This series iron ore crusher reall
y supply simpler, higher efficient lower cost machines for clients.
Iron ore grinding mill line
Ball mill is used as iron ore grinding mill. In iron ore concentrator, ball mill and regrinding ball mill is used to grind iron ore into fine powder.
Raymond Mill is applicable to high fineness powder manufacturing of over 300 non-flammable and non-explosive materials, with Mohs’ scale of hardness no more than Grade 7, and humidity less than 6?, which are widely used in mining, silicate and chemical engineering and building Industry. For example, barite, calcite, feldspar, talc, marble, limestone, dolomite, fluorite, lime, active floridin, activated carbon, bentonite, kaolin, cement, rock phosphate, gypsum, glass, manganese minerals, titanium minerals, copper minerals, chromium minerals, refractory materials, thermal insulating material, coal tar, coal powder, carbon black, pottery clay, bone powder, titanium dioxide, iron oxide, quartz, etc. Product size can be freely controlled within 80-325 mesh, and in particular, some can be 600 mesh.
High-pressure micro-powder pulverizer is used for super fine powder proccessing of non-flammable and non-explosive materials with Moh’s hardness below 6 and humidity below 8%, such as kaolin, limestone, calcite, talcum,marble, barite, gypsum, iron oxid red, iron oxid green, aluminium hydroxide, pigment, bentonite and ceramic.High-pressure Micropowder Grinder has a higher quality than ball mill.
Iron ore crushing plant
Almost all of the iron ore that is mined is used for making steel. So we need the extraction of a pure metal from its ore. The extract the metal from ores, several physical and chemical methods are used. The method used depending upon chemical properties and nature of the ore from which it is to be extracted. It involves four main steps:
1. Crushing and grinding of the ore.
2. Concentration or dressing of the ore.
3. Reduction to free metal.
4. Purification or refining of the metal.
Vibrating feeder and screening machine used in iron ore mining
Vibrating feeder is the machine used to feed iron ore evenly to iron ore crushing and grinding machine in iron ore processing plant.
Vibrating screen is the screening machine used in iron ore crushing and screening plant. It screens out the appropriate iron ore particles, these particles enter into ball mill for grinding.
