One of Western Australias gold mines required an oily water treatment system to treat wastewater from the heavy
A mine generates large amounts of highly concentrated wastewater due to contact between water and various types of minerals. The origin of these effluents can be found in the distinct processes undertaken in mining, in addition to drainage from rainfall. Mining
Foureaux et al., , which utilized a membrane distillation process for gold mining wastewater treatment, emphasized that sulfuric acid and metallic compounds from the feed wastewater were the main contributor for membrane wetting and its degradation. Due to that fact, the process was constrained to a distillate recovery of approximately 35.

Gold and silver mining began at Summitville around 1870. The latest mining operator, Summitville Consolidated Mining Corporation Inc. SCMCI, mined the site from July 1986 through October 1991 and abandoned the site in December 1992. The company opened a pit heap leach gold mining operation, using cyanide to extract the gold. The EPA Emergency Response Branch assumed responsibility of
The most common practice for the management of NaCN is the incorporation of cyanide destruction in the metallurgical flowsheet and the use of tailings impoundments and holding ponds for natural attenuation of cyanide destruction residues such as NH4-N and CNO. At most mine sites there is no active management of NO3-N and SCN in wastewater.
Nov 22, 2012 The physical and chemical qualities of the process effluent and the tailings dam wastewater of AngloGold-Ashanti Limited, a gold mining company in Ghana, were studied from June to September, 2010. The process effluent from the gold extraction plant contains high amounts of suspended solids and is therefore highly turbid. Arsenic, copper and cyanide were identified as the
