Typically thermal power plants are located near to surface coal mines that produce huge amount of fly ash as a waste byproduct. Disposal of fly ash causes significant economic and environmental problems. Now-a-days, research is going on for bulk utilization of fly ash. In order to increase its percentage utilization, an investigation was carried out to evaluate its potential for haul road const...

In this research, a high porous silicate mining waste that was prepared from Syah Kamar Polymetal Porphyry mine in order to malachite green dye (MG) removal has been applied. The characterization of this natural mineral was determined using the XRD, XRF, SEM and FT-IR analysis. The MG adsorption onto high porous activated waste was studied based on the parameters of pH, temperature, adsorbent d...

Large quantities of iron-ore tailings are being generated annually in the world from mining and processing of iron ores. It has been estimated that around 10-15% of the iron ore mined in India has remained unutilized and discarded as slimes during mining and subsequent processing. Soil contamination resulting from mining activities affects surrounding flora and fauna and presents a large clean-...

The characterization of metal release and attenuation in mining waste rock drainage has traditionally relied upon an array of mineralogical and geochemical techniques. Recent advances in analytical instrumentation now allow robust measurements of minute variations in the isotopic composition of metals in environmental samples, which have become a powerful new tracer of their fate. Here we provi...

Antimony (Sb) is an element with a growing concern due to its toxicity, but also because of criticality. While the impact Sb mining documented in literature from China and Europe, still little data available concerning environmental Vietnam. This paper presents results exploratory study mine waste soil samples Mau Due (North Vietnam). The chemical mineralogical composition was determined as wel...

This study investigates the application of models traditionally used to estimate erosion and sediment deposition to assess the potential risk of water quality impairment resulting from metal-bearing materials related to mining and mineralization. An integrated watershed analysis using Geographic Information Systems (GIS) based tools was undertaken to examine erosion and sediment transport chara...

The Giant Mine, located in Yellowknife, Northwest Territories, Canada has been operating as a gold mine since 1948. Giant has been primarily an underground operation which used roaster technology to remove of gold from refractory arsenopyrite ore. The roasting process produced arsenic trioxide bearing dust as a waste product. This dust was pneumatically conveyed into underground storage chamber...
