KCM 2000 Group is the Principal of the non-ferrous Smelter located near Plovdiv, Bulgaria with annual production of 70 000 tpy lead and 75 000 tpy zinc including their alloys and compounds. As part of a large-scale renovation plan, a new brown field lead smelting plant was commissioned in the middle of 2014. It was designed to produce 75 000 tpy crude lead and 55 000 tpy sulphuric acid in an economically feasible and environmentally friendly way substituting the old sintering-blast furnace technology.
The New Lead Plant represents a unique combination of sub-systems and applies Best Available Techniques. The smelting technology allows treatment of primary and secondary lead-containing materials in a wide range of ratios. Sulfuric acid production is reduced to lowest possible rates and depends solely on sulfur content in the TSL input. The technology creates no other products than lead bullion, low Pb slag and sulphuric acid.
