Extracting and Reusing Metals from Mining

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?

1. 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,

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

3. 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.

4. 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...

5. Hi

   What volumes are you talking about?

6. Hi Ravi,

   You can look at our SaferEx. It serves as a disinfectant, coagulant and sediments heavy/unwanted metals from water. It has proven efficient in separating (sedimenting) Iron, Manganese, etc. (see attached photo) and read more from this link: https://drive.google.com/file/d/0B5vq4wO9sNRoRjJTUU9JVjRjQVU/view?usp=sharing

7. There are some options, from harvesting with special plants, roasting and then leaching, to Ion Exchange technologies... what is your aim?

8. you can use specialized plants to uptake the metals. The plants can be harvested and the metals extracted back out of them. Let me know if you would like more information.

9. As said, there are several methods available. One wonders if the metal concentrate, remaining after mining waste water treatment, is sufficiently pure to further process economically, as compared to a concentrate produced directly from ore processing. And if so, will you be paid accordingly by the refinery for offering a precious raw material or do they ask you to pay, because what you deliver is actually a waste that you otherwise have to dispose off at great cost?  

10. Question needs to be reframed ! If specific situation is shared, solutions can be suggested.

11. There are several methods for extracting metals from effluents from the mining industry, depending on the concentration, the method is chosen, for example at low concentrations the best extraction method is the ion exchange adsorption. The metals are the most diverse, depending on the characteristics of the formation of the mine that produces these metals.
