%X The purpose of this article is removal of copper, nickel, chromium and zinc from their model solution by precipitation and adsorption processes where metal ions are adsorbed onto the surface of materials. Inorganic granular material (Slovakite) with high content of MgO.CaCO3 was used in this study. Slovakite proved to be efficient for copper, nickel and chromium removal. Langmuir¡äs and Freundlich¡äs isotherm models adequately describe adsorption process from aqueous solution. Removal efficiency of metals, rate of metal removal and bond strength between Slovakite and metal was investigated. Slovakite is an alkaline adsorbent; therefore, pH value increases with concentration of Slovakite in solution. On this account, efficiency of metal removal depends not only on adsorption processes but also on precipitation processes.
