Uranium Mining and Extraction from Ore
Mar 21, 2012· Uranium Extraction. Uranium leaching is the process by which the uranium is extracted from the raw ore by reacting the material with acid or base. Fig. 2 shows a general process flow for the uranium extraction process. Prior to the leaching process, the ore is often given preliminary treatments that can include roasting and grinding.

Minerals and the environment | Minerals you | MineralsUK
Water is an important consideration in minerals planning as it often plays a key role in mineral extraction and processing. Mineral extraction operations must not significantly reduce river or groundwater levels. Water drainage from mineral extraction is monitored closely as dissolved or suspended minerals can damage fisheries and wildlife habitats.
