The aim of the research was to determine magnetic susceptibility (m.s.) and heavy metals content (h.m.c.) in waste materials being used in cement factories in Opole Province, as well as to make the choice of the most advantageous wastes from the environmental protection point of view. In addition to m.s and the content of 10 metals, pH and specific conductivity (s.c.) of samples were determined. According to Polish classification of wastes, investigated samples belonged to 3 groups: 01, 06 and 10. The result shows, that the most advantageous are waste raw materials (01) having less m.s., h.m.c. and s.c, in comparison to industrial wastes (06 and 10). Very high content of metals and s.c. of metallurgical wastes indicates, that they are the most harmful to the environment. Statistically important correlations between m.s. and other parameters (h.m.c. and s.c.) show the possibility of usage of m.s. measurements in assessment of h.m.c. and s.c. of wastes. Correlation coefficient values ranged from 0, 760 (Ni) to 0,953 (Zn) and were important with a probability above 99%. M.s. measurement method could make it easier to cement factories to come to the decisions concerning the usage of wastes in cement production technology.
