Tailings ponds, essential components of mining operations worldwide, present considerable potential hazards downstream in the event tailings dam failures. In recent years, instances failures, carrying environmental safety hazards, have occasionally occurred on a global scale due to limited technical approaches available for supervision ponds. this study, an innovative WebGIS-based unmanned aeri...
Online radon and thoron monitors have been developed using ZnS(Ag) detector for continuous monitoring of concentrations in occupational and general environments. Their performance has been tested successfully both in laboratory and field conditions. Special features of these monitors include low cost, high sensitivity and non-interference of humidity and trace gases. The capability of these rad...
PT. Dinamika Sejahtera Mandiri has 6 settling ponds. One of the factors that must be considered in mining activities is residue from washing process will enter pond. Pool conditions at The Dynamics seems to almost full, which requires a study on maintenance pond carried out. This research aims plan and schedule dredging addition tools for optimal maintenance.The was conducted by collecting prim...
The acid-forming potential of lead/zinc (Pb/Zn) mine tailings at Lechang City of Guangdong Province was studied using both net acid generation (NAG) and acid-base accounting (ABA) methods. The pyritic and total sulfur contents of the tailings were 12.6% and 18.7%, respectively. The mean acid neutralization capacity (ANC) was 63.5 kg H2SO4/t while three oxidized tailings samples had an ANC less ...
Mineral forms in rhizosphere and bulk substrate were examined for selected plant species (Cardaminopsis arenosa, Calamagrostis epigeios, Deschampsia caespitosa, Festuca ovina, Silene vulgaris, Viola tricolor) growing spontaneously in the close vicinity of a tailings pond and in a zone of eolian transmission of waste particles. Samples of substrates and plant roots were taken from sites in the B...
