Iron Ore Crushing Machine

The primary crusher is jaw crusher and cone crusher. Our jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, iron ore, etc. the pressure resistance strength is under 200 Mpa, which is suitable for iron ore primary crush.

Iron Ore Mining Method

Some main iron ore mining techniques such as drilling, blasting, excavation, extraction, crushing, grinding, beneficiation, and processing of iron ore produce iron or steel. “Extraction” is the process of removing ore material from a deposit and encompasses all activities prior to beneficiation. Iron ore beneficiation includes concentration, generally by physical removal of unwanted gangue; also considered beneficiation is the regulation of product size, or other steps such as agglomeration to improve its chemical or physical characteristics prior to processing. Processing of the concentrated product into iron or steel typically involves the use of pyrometallurgical techniques.

Currently, some ores are high enough in iron content (greater than 50 percent) to be sent directly to furnaces without beneficiation activities other than crushing and washing. Crushing is an important iron ore mining techniques, there are many detailed technologies in this technique, it will produce fine iron ore particles and prepare for the further iron ore mining technique of beneficiation and processing process. Most ores extracted today, however, must undergo a number of beneficiation procedures to upgrade the iron content and prepare the concentrate for the blast furnace. Technological advancements at blast furnace operations require ore feed of a specific size, structure, and chemical make-up for optimum efficiency.
