Abstract
- The non-metals and building materials industry accounted for approximately 8 % of the total industrial output in Croatia during year 2004. Nowadays more than 200 trading companies in Croatia deal with the exploitation of solid mineral raw materials, and almost 50 % of them exploit technical stone. In the majority of technical stone quarries, the deposits of carbonate rocks (limestone and dolomite) are exploited, whereas in only eight quarries the eruptive rocks are exploited. If raw material contain impurities, which necessitates wet processing operation, waste water must be cleaned before being let out of the processing plant or returned to the dressing process. In the paper the waste water treatment in technical stone quarry is presented.
