"Apart from a high concentration of iron, mine water can also contain a higher concentration of manganese. Extraordinarily high concentrations can be found in acid waters from the surroundings of ore deposits, e.g. the water from the sulfitic ore deposits in Smoln\u00EDk contain up to 40 mg.l-1 of manganese. The legislation ordains discharge of water into surface water with a maximum concentration of manganese of 1 mg.l-1, and therefore it is vital to reduce the content of manganese in the mine water to a permissible value. Within the research work, a variety of demanganization methods were tested. In conclusion of the paper, so far most optimal method of manganese removal from acid mine water is suggested."@en .
