In order to minimize water management problems due to excess water at a mine site, or to address changing constituents or contaminant levels over time, Pall has designed its water …
Current low-cost technologies for the removal of heavy metals from mining wastewater include biosorption, adsorption, CWs (Constructed Wetlands) and waste stabilization ponds. This chapter focuses on sustainable mining wastewater treatment …
Chapter 2 reviews the relevant parts of technology and biotechnology to remove heavy metals (such as copper, arsenic, lead and zinc) from wastewater. The chapter places special emphasis on gold mining wastewater and the use of low cost materials as sorbent.

The following paper examines a surface flow constructed wetland in northwestern Ontario, Canada, designed for the bioremediation of effluents at an operating gold mine. This study specifically examines the data for the 2011, 2012, and 2013 treatment seasons, which extend from May to October in each year.
A gold mine effluent is sampled at the inlet of an operating treatment plant. The effluent is alkaline (pH 7.5-8.4) and contains high concentrations of SCN- (435±53 mg/L) and NH3-N (41±8...

Six treatment options were evaluated to remove or reduce toxicity caused by the suspected contaminants. The six treatments investigated included: (1) Granular activated carbon (GAC) …
Gold mines conventionally use lime to neutralize acid water generated during mining and processing of the ore. An alternative approach is to use limestone for the neutralization …
This study aims to evaluate the optimal conditions for gold mining effluent treatment by crossflow membrane filtration regarding the following variables: nanofiltration (NF) and reverse osmosis (RO)
In order to minimize water management problems due to excess water at a mine site, or to address changing constituents or contaminant levels over time, Pall has designed its water treatment system to be highly "modular" and offers it in a multi-rack-based configuration.
Gold-mine effluents are often characterized by high concentrations of copper, ammonia and cyanide derivatives (mostly cyanates and thiocyanates). While not acutely toxic to birds, this water can be acutely toxic to fishes and invertebrates.

Gold mines conventionally use lime to neutralize acid water generated during mining and processing of the ore. An alternative approach is to use limestone for the neutralization process. The fluidised-bed limestone neutralisation process …

Six treatment options were evaluated to remove or reduce toxicity caused by the suspected contaminants. The six treatments investigated included: (1) Granular activated carbon (GAC) + zeolite; (2) air stripping + GAC; (3) zeolite + GAC; (4) multistage GAC; (5) alkaline chlorination + dechlorination; and (6) bentonite clay based polymers.
