Description	Neutralization of acid mine water is the fundamental step in acid mine water treatment, accompanied by the elimination of iron, partial elimination of manganese and dissolved components of heavy metals, before its discharge into the receiving body. Most frequently lime hydrate, in the form of milk of lime, is used in the neutralization process. The negative outcome of lime hydrate application is an increase in the treated water hardness and a formation of sludge difficult to drain, which could partially be solved using calcium carbonate or combining both agents. The paper observes the effects of calcium carbonate in the neutralization of acid mine water in the locality of Jiří Mine in the Sokolov Region. Attention is paid to testing neutralization methods that are both economically favourable as well as technologically effective. Samples were studied for the time variations in pH values, initial and final concentrations of iron and manganese. Last but not least, it includes an economic appraisal considering the current costs of the agents. As for the neutralization agents, the cost savings are as much as 30% when combining the two agents; under the given conditions the sole application of calcium carbonate proved as economically unprofitable.
