Mining & Minerals
Mining effluents can be caused by:
• Wash waters.
• Flow Process acids.
• Water leaching, flotation and concentration.
• Effluents from refining and gas scrubbers.
Mining & Minerals.
Meanwhile, rain that infiltrates the tailings of the mine can also cause oxidation, hydrolysis, washing, etc. producing a highly contaminated wastewater.
The contact between minerals and water, by process or rain, can produce distinct reactions. The effluents produced are of diverse compositions, depending upon the nature of each mineral, since there are those more or less soluble, hydrolysable and non-hydrolysable, as well as sorbents and non-sorbents. Thus, the discharge of such wastewater can provoke serious consequences in mining and its environment by completely altering water chemistry.
Traditionally, physico-chemical or biological methods have been used to treat these effluents. Presently, zero discharge has proven to be the smartest choice. It ensures the protection of the ecosystem and provides for water reuse in places where access to water is limited. In addition, zero discharge is most economical long-term alternative once installation costs have been recuperated.
We, at Fluid Sep Technologies can guarantee zero liquid discharge , depending on the composition of the effluent, with other membrane technologies or pretreatment processes. That can achieve a 95% rate for pure water ready to be reused. Moreover, solids rejected in the process can to be sent to waste management.
