 abstract={Due to the decline in the production of ceramic building materials (bricks, ceramic hollow blocks), alternative possibilities for managing clay raw materials and using equipment for their processing in production plants are sought. Therefore, the subject of this paper is the assessment of the suitability of selected raw clay materials from southeastern Poland for use as mineral sorbents. For this purpose, the following raw materials were used: Krakowiec clays, clay-silica raw materials from the Dynów Foothills, and Krosno slate in their natural state, as well as after sodium and acid activation. Sorption of copper, nickel, zinc, and chromium from their salts was carried out on the samples using the batch static method, aqueous solutions of experimentally determined concentrations. Experiments were performed using an AAS analyzer. The effect of the sorption environment was determined in conditions of changing pH. It was found that the sorption of heavy metals depends to the greatest extent on pH and smectite content. However, it is also determined by the content of other mineral components, such as illite, kaolinite, opal, zeolite, iron, and manganese minerals. The influence of chemical modification of samples on sorption parameters and morphology of samples was also investigated. The latter factor was considered based on SEM micrographs. On their basis, prospects for developing the tested mineral raw materials for use as a medium-quality sorbent (clay-silica raw material) and in constructing mineral barriers (Krakowiec clays) were found.},
