The co-mixing of tailings and waste rock involves the intimate blending of tailings and waste rock to create a new material (Co-Mix) with superior physical and hydraulic properties. The new material has a low hydraulic conductivity, low compressibility, high water retaining capacity and high...

Phosphate induced stabilisation has been used to create passive iron phosphate coatings on pyrite and pyrrhotite. The formation of solid phosphate coatings on sulfide grains thereby inhibits sulfide oxidation. The aims of the study were to determine whether phosphate induced stabilisation could...

Quantitative probabilistic ecological risk assessment has been used to evaluate the likely effect on fish diversity and abundance of filtered and bioavailable metals in streamwater affected by acid drainage from the abandoned and remediated Rum Jungle U/Cu mine in the Northern Territory of...

The surface waters in regions with acid sulfate soils (ASS) can contain high concentrations of acidity and dissolved metals. These soils cause problems for agriculture, construction and development. The water can be neutralised through many techniques, however a technique that is low in...

Acidic and metal-rich waters have been discharging from Sullivan Mine, West Coast, New Zealand since the closure of the mine during the early- 1990s. This has resulted in a decrease in pH from a background of 4.5 to 2.8 and an increase in metallic elements in nearby Rapid Stream. In addition to...

Peak Gold Mines (PGM), a member of the Rio Tinto Group, is an underground and open cut gold mining operation located near Cobar, NSW. A multi-phase study was initiated in 2001 in support of developing a dry ‘moisture store and release’ cover system design for the PGM tailings dam, which contains...

Chapin, T. P., Wanty, R. B.

Historically, most investigations of biogeochemical cycling in acid rock drainage systems involved synoptic sampling over longer time periods (one sample per week or month) or intensive time series studies over a few hours or days. However, many important episodic loading events, such as seasonal...
