Gold tailings (GT) and slag disposed of in the landfill affect the environment. This study
investigated the green process for the utilization of non-radioactive gold tailings and …

Zeolites are commonly used as adsorbents for metal removal in most applications eg in
wastewater. However, the ubiquity of iron in such systems may, in the long-term, distort the …

With the decline of gold grades of primary resources in many parts of the world, gold
recovery from primary resources may become unprofitable. Therefore, the identification of …

Metal binding by algae has enormous potential for environmental bioremediation of
industrial and urban wastewater. Algae have been proven to be cheaper and more effective …

In recent decades, much research has been paying attention on the treatment and
desalination of acid mine drainage (AMD) with minimal focus on the recovery of minerals …

Acid mine drainage is generated when mining activities expose sulphidic rock to water and
oxygen leading to generation of sulphuric acid effluents rich in Fe, Al, SO4 and Mn with …

Wetlands are well known to be efficient at sequestering pollutants from contaminated water.
We investigated metal accumulation in the peats of the Klip River, a natural wetland that has …

Abstract Basic Oxygen Furnace (BOF) slag has been widely used for Acid Mine Drainage
(AMD) treatment with its reaction chemistry and contaminants attenuation mechanisms …

Batch experiments were conducted to study the effects of contact time, pH (3 to 8), initial
concentration, presence of carbonate, sulphate, and competing ions (Fe 3+, Ca 2+, Sr 2+ …

The transport and retardation of radioactive elements in hyper-alkaline conditions of
radioactive waste repositories is a challenging field that is still poorly understood. In this …
