Extracting and Reusing Metals from Mining

Question

Is it possible to recycle and reuse extracted metal from mining wastewater? 
Is there a material which can act as a coagulant, flocculant or act as a porous membrane to extract the metal from mining with the possibility of reusing them? 
Which metals have so far successfully been extracted and reused and with which materials and methods?

Dear all,
likely to work in coal mine,eventually action will be resumed to extract metals(heavy/low).propose us to formulate a multi-membrane as a porous nature at low cost basis.further, which can reuse as a valuable things,such as chemical additives,concrete/cement development etc..
thank you all,

What type of mine are you studying and where is it located?

Joseph Cotruvo · Answer

I assume you are really interested in extracting precious metals since that is where you have the potential for making a return. That industry often uses cyanide at basic pH as a way of isolating  gold, silver etc. from low strength solids.

There are plenty of methodologies, some of them more traditional based on precipitation, coagulation or chelation and there are more innovative based on electrocoagulation, nanofiltration, bioelectrochemical processes, etc...
