Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ...
Adsorption of metal ions from fine coal tailings dump waste water using bio-char
Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ...
