iron ore processing plant water use

  • Water Requirements of the Iron and Steel Industry

    ferent processes of iron ore concentration are devised specifically for the various kinds of ore. These processes result in a wide range of water use from 124 to 11,300 gallons of water per ton of iron ore concentrate. Water use in con­ centration plants is related to the physical state of the ore. The data in this

  • Dry Processing Vale

    During the wet processing, water is used to classify and purify the iron ore, removing impurities (such as silica) that affect the final product quality. Then, material must be exposed to moisture reduction processes in order to be stacked and transported to the clients. This processing route is used for the ore that has low iron content.

  • Iron Ore Pelletizing Process: An Overview IntechOpen

    7/10/2017· Pellets are obtained by adding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension.

  • New dry iron ore processing technology developed

    5/25/2016· The method does not use water to process iron ore, instead it transforms mining tailings with low iron content and no commercial value into high iron content and low contaminants, making it economically viable. As iron ore must be composed of grades of at least 58 per cent, mining companies stack the lower grade material on tailings dumps.

  • Wasting water on dust control Australian Mining

    9/15/2010· According to a report by Western Australia’s Water Corporation in May this year, 70% of the Pilbara region’s water was used in mining activities. Furthermore, around 50% of the water in Harding Dam, the principal reservoir for Karratha and Port Hedland, is used for dust suppression on the stockpiles of iron ore in the ports.

  • Managing water consumption in mining

    8/21/2013· In 2005 the mine used more than 3,500 megalitres of water from the lake to run operations. By 2009 they had reduced this to 300 megalitres a 95% drop. Rio Tinto did this by capturing and recycling water used by the processing plant, the biggest user of water, and capturing seepage from tailings, which also get recycled.
