Neutralizace kyselých důlních vod uhličitanem vápenatým

Abstract

The task of the diploma thesis was the increasing pH of the acid mine water. To achieve it I used the methods of neutralization, in concrete terms the neutralization by calcium carbonate and after the subsequent detection of the optimal amount to the needed pH value was done, also the neutralization of its combinations with solution of calcium hydrate. The real samples of the acid mine water were used in the experiments taken from the location of the pit Jiří in Sokolov, specifically from Lomnice 2B and ČS J3, belonging to the company Sokolovská uhelná, law successor, a.s. The aim of the thesis was to choose economically and technologicaly the most effective amount of the fine ground calcium carbonate for the neutralization of acid mine water and its combinations with solution of calcium hydrate and then conversion into the technical reagences in respect of the usage in the technology of the operation of the mining companies.
