Treatment of Berkeley Pitlake Water Using the Green Precipitate Process
Acid mine drainage (AMD) is usually treated by air oxidation followed by addition of lime to precipitate metal hydroxides and calcium sulfate. Geo2 Limited of Melbourne, Australia, has developed and patented a novel alternative precipitation scheme based on the formation of mixed valency, M(II)-M(III), hydroxide sulfate salts. When the composition of AMD has an appropriate ratio of Fe(II):Fe(II...
متن کاملBiosulfides precipitation in weathered tailings amended with food waste-based compost and zeolite.
Tailings are mine wastes in the form of slurries stacked in mine sites abandoned after the exhaustion of ores. There are approximately 5000 abandoned mine sites in Korea, and tailings have become a serious environmental problem. Long-term environmental exposure of tailings can cause release of acidic and high concentrations of sulfate- and metal-contaminated water (acid mine drainage, AMD). Org...
متن کاملCharacterization of the Bacterial and Sulphate Reducing Community in the Alkaline and Constantly Cold Water of the Closed Kotalahti Mine
Drainage from metal-sulphide rich rocks may cause considerable environmental stress in the form of elevated sulphate and heavy metal contamination of the environment. Mine draining effects from closed mines may be abated using indigenous and introduced microbial communities for sulphate reduction and metal precipitation at the mining site. Here we characterized the general and sulphate reducing...
متن کاملSulfidogenic biotreatment of synthetic acid mine drainage and sulfide oxidation in anaerobic baffled reactor.
The treatment of synthetic acid mine drainage (AMD) water (pH 3.0-6.5) containing sulfate (3.0-3.5 g L(-1)) and various metals (Co, Cu, Fe, Mn, Ni, and Zn) was studied in an ethanol-fed sulfate-reducing 4-compartment anaerobic baffled reactor (ABR) at 32°C. The reactor was operated for 160 days at different chemical oxygen demand (COD)/sulfate ratios, hydraulic retention times (HRT), pH, and me...
متن کاملField trial of an ion exchange based metal removal technology in the treatment of mine waters
A pilot scale field trial for a novel metal removal technology in the treatment of mine waters was performed using mine water from White Tip, part of the former Snailbeach lead mine in Shropshire, United Kingdom (UK). The water is circum-neutral pH and contains elevated zinc (Zn), cadmium (Cd) and lead (Pb). The novel treatment process is based on ion exchange (IE) using a bespoke mesh in a rot...
