  • How to Make Filtered Tailings Feasible | E & MJ

    "A big filtered tailings solution probably needs around 10 years to be competitive and pay back the investment in the conveyors and filtration equipment. And for large concentrators that are looking at big pressure filters, like in Chile, the cost of water needs to be more than $3 a cubic meter (m 3 ) for it to start making economic sense or they need to be very near the end of life .
