General. India has the fourth largest iron ore reserves in the world after Russia, Brazil, and Australia. As per the survey conducted by the Indian Bureau of Mines (IBM) in April 2000, India had 9919 million tonnes of recoverable reserves of haematite and 3546 million tonnes of magnetite.As good quality iron ore deposits are depleting very fast, beneficiation technologies have to beGet Price
extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often moreGet Price

Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.
