Technology of Integrated Treatment of Mine Water with Accompanying Extraction of Non-Ferrous Metals

What is it about?

Spent mines are the sources of water, contaminated by non-ferrous metals, manganese, iron, silicon, calcium, etc. The possible way of treatment of a weakly mineralized mine water with elevated contents of ions of nickel, manganese and hardness salts is ion exchange using Lewatit Monoplus TP 207 resin in combination with a chemical softening, microfiltration and disinfection. The laboratory studies of mine water treatment were carried out on the pilot plant with the flow rate of 5 liters per hour. The treated mine water meets the quality requirements for potable water. The sulphuric acid regeneration of ionite was carried out after its saturation by non-ferrous metals. The obtained nickel and copper containing eluate may be used in technology of nickel and copper sulphate production.
