Oct 15, 2019 With advent of novel technologies, mining companies are now figuring out ways to extract valuable metals from tailings. In gold, copper sulfide and iron ore tailings, the potential of extracting minerals is an opportunity. Reprocessing tailings to collect the valuable minerals can be a cost-effective approach compared to processing virgin material

Sep 26, 2013 Posted September 24, 2013. There is a very old, and very large old gold mine Stamp Mill I am interested in reprocessing some of their tailings. I am thinking about gathering some 5 gallon buckets of it, and running it through my 5 gallon tumbler with a few crushing balls, and mercury. Then retorting the mercury
