3. MINING AND INDUSTRY
Water is one of the key elements in mining and industrial operations.
Mines tend to be self sufficient in the development, management and use of
their water requirements, while industries normally rely on municipal
water supply. For environmental and economic reasons, industries and mines
increasingly are adopting water recycling techniques as a means of
reducing their consumption of water. This both reduces costs of production
and enhances the environmental benefit that accrues to the community.
However, in so doing, technologies are required to improve and restore the
quality of recycled waters. However, the technologies in these sectors can
vary considerably both in complexity and extent, depending on the type and
sophistication of the industry or mine. While all of the technologies
described in this chapter may be considered for use by the mining and
industrial sectors, some may be similar to ones described above for the
agricultural and domestic water supply purposes.
