Abstract
Transition of nonferrous and precious metals in the solution with filtration displacement by flow of water and lignosulphonates solutions through the layer of old tails of copper-nickel ores of Norilsk is investigated. The experimental kinetics of dissolution of nonferrous and precious metals and comparison of speeds of the filtration at use of water and lignosulphonates solutions are presented. Moving nonferrous and precious metals in a direction of water filtration and the filtration of lignosulphonates solutions is studied. Efficiency of sulfite alkaline solution for conversion to the movable state of nonferrous and precious metals in aged mineral processing waste is established.
