Water Recycling Application at Iron Ore Mine | Kinetrol ...

Mining corporations need water - a lot of water - to make bare rock give up its valuable minerals. Water is used for the extraction of minerals that may be in the form of solids, such as coal, iron, sand, and gravel. The category includes quarrying, and milling (crushing, screening, washing, and flotation of mined materials).

Mining & Industrial Process Water Treatment

In mines with a positive water balance, treatment to a high water quality standard before disposing of excess water is challenging as they may not disturb the local ecology. In mines with a negative water balance, water conservation is a big cost-incentive and treatment for recycling is the best option.

Froth Flotation of Iron Ores

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today's price, US$5,842/tonne, if that material could be reprocessed and an extra ...
