Ore Mining and Dressing Effluent Guidelines US EPA

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 entering mines.

3 Technologies in Exploration, Mining, and Processing

Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps). In-situ mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not require the excavation, comminution, and waste disposal steps.
