In area of zinc and lead exploration the most common elements of landscape are mine spoil-heaps and also dumps and settling tanks connected with zinc and lead metallurgy and ore flotation. They are located in the northern part of Katowice Province, on a line Piekary - Bytom - Bukowno - Olkusz and cover area of about 350 hectares. The individual settling tank in this area is between 15 and 40 hectares and considerably deforming landscape. A fine-grained dolomite is main material of tank sediments. The sediment contains maximally up Io 8.0% of Zn, 1.5% of Pb and Cd in content usually over 100 mg/kg. In spite of high salinity and high Zn, Pb and Cd content the settling tanks can be soil-less reclamated but the first stage of the reclamation should be trying to stop weathering and erosion processes. For the soil-less reclamation so
