This study set out to establish the major minerals at Dorowa and determine which of those are likely to host metals that may leach into surface and groundwater. This study comes after a preliminary assessment of the water quality in the Save River downstream of the Dorowa phosphate mine in Zimbabwe showed an increase in conductivity, iron content, manganese content, nitrates and hardness when c...

Acidovorax sp. strain NO1, isolated from gold mine soil, was shown to be a facultative anaerobic arsenite-oxidizing and nitrate-reducing bacterium. The reported draft genome predicts the presence of genes involved in arsenic metabolism, nitrate reduction, phosphate transport, and multiple metal resistances and indicates putative horizontal gene transfer events.

abstract with increasing population, mine activities for metal proceeding are also increasing, so environment will be influenced by contaminant especially heavy metals. in situ immobilization of heavy metals using inexpensive amendments is considered as a simple and cost-effective approach for reducing heavy metal contamination. in this research we used sequential extraction for assessing reduc...

Phosphate tailings pose significant risk to the environment as point sources of basic, carbonate-rich effluents. This waste may be judiciously used for the biofertilizer preparation. The enrichment of compost by adding low grade rock phosphate also offers a potential preposition for the effective utilization of insoluble P. Experimentally, the compostable material (Biogas spent slurry) is mixed...

Red shale is widely distributed among the deep mine areas of Kaiyang Phosphate Mine, which biggest underground phosphate China. Because effect various factors, such as high stress, ground water and so on, trackless transport roadways in were difficult to effectively support for a long time by using traditional supporting design methods. To deal with this problem, some innovative works carried o...
