In fact, water is treated in a systematic fashion by various recycling methods. Each type of water that is produced can be used for specific things.
The process water used at mineral processing operations is made up from a number of available water sources, which can be classified as recycled water streams or make-up waters. The recycled water streams are commonly the tailings and concentrate thickener overflows, filtrate from the concentrate filtration plant and tailings dam return water.
Right now, we're focusing on renewably powered advanced desalination of seawater, zero waste and recycled water reuse. Longer term interests include advanced water recycling treatment, brine processing, smart sensors and smart water usage, industrial demand reduction processes, and stormwater harvesting.
Can result in reduced plant growth and plant damage and can impact on freshwater plants and invertebrates in natural ecosystems if discharged directly with little dilution. Most common salts are sodium chloride. Sodicity. Excess sodium in recycled water can cause soil dispersion/swelling, reducing water infi ltration on heavier textured soils. ...

Aug 15, 2018· Therefore some minerals processing operations started evaluating and implementing water recycling to reduce fresh-water intake already in 1970s (Bailey, 1970, Pickett and Joe, 1974), bringing benefits both from cost effectiveness and sustainability points of view.
Mineral processing plants usually operate with water in a closed circuit mode. For this large quantities of water have to be recycled from various unit operations continuously. To compensate natural losses small quantity of fresh make up water is added into the circuit. As a result of recycling, a gradual build up of residual concentrations of flotation reagents (frothers, collectors ...
for specified uses. For example, recycled water can be used in agriculture, in manufacturing and mineral processing, and to cool electrical power plants. There are some management challenges to work through, but the main factors that limit the adoption of water recycling are economic (the cost of treatment, storage and delivery) and attitudinal.
