• Ore Mining and Dressing Effluent Guidelines US EPA

    What Is Ore Mining and Dressing?Rulemaking HistoryAdditional InformationMine operators extract ores (metal-bearing rock) from underground mines and surface mines using machinery, explosives and chemicals. Extraction processes include dressing (picking, sorting, washing of ores), milling (crushing, grinding, etc.) and beneficiation (processing to improve purity/quality).Wastewater is generated during the mining process from groundwater produced during ore extraction, from water used by operators for equipment cooling and dust control, and from precipitation
