Water Management – Maximising water use efficiencies
The Ostara process promises the opportunity to treat and discharge or reuse excess pond water volumes on a continuous basis.
Water is an essential part of mining and processing operations in both the phosphate and potash sectors, being essential for the processing of the mineral ores, dust control, irrigation, the cooling of machinery and staff amenities. Minerals processing tends to use the most water within a mining operation.
Mines can use a large proportion of the available water in a region, particularly in phosphate operations conducted in the semi-arid regions of the Middle East. Companies tend to view water strategically and are driven to use water efficiently due to its low availability in some areas and the need to ensure continuing operations, the expectations of the community and the cost of using water.
Mines get their water from a variety of sources, depending on local conditions and requirements. Sources include rivers, groundwater aquifers, rainfall, water recycled on site, local authority fresh water supply or water supplied by a third party, including other mines. While water quality is important for some aspects of mining and minerals processing, lower quality water such as treated effluent and saline groundwater can be used for some purposes. This reduces a mine’s demand for higher quality water, which can have environmental benefits as well as leaving higher quality water for others in the community…
