Abstract The results of the toxic elements behavior predicting in gold mining technogenic waste during their draining with seasonal precipitation (case study of the tailings management facility of Tokur Mill, Amur Region, Russia) present in this article. The predictive assessment was made on characteristics basis of the tailings management facility material: the geochemical composition, migration ability of elements in model experiments using atomic emission and mass spectral methods, calculation of acid-producing and acid-neutralizing potentials. The substance of the tailing management facility has a high acid-neutralizing potential due to the carbonates in it, which contributes to the neutral and slightly alkaline drainage flows formation. Under these conditions, the migration of Cd, Bi, Pb, Sr, Co, Cu, Ni, Zn, Sb risk is low, and water migration of oxygen-containing As risk anions is very high, since the share of its mobile compounds in the tailings management facility material is 90-92%.

Abstract There is presently overwhelming scientific consensus that global climate change is indeed occurring, and that human activities are the primary driver. An increasingly resource and carbon constrained world will continue to pose formidable challenges to major industries, including mining. Understanding the implications of climate change mitigation for the mining industry, however, remains limited. This paper presents the results of a feasibility study on the implementation of a clean development mechanism and greenhouse gases (GHGs) emission reductions in the gold mining industry. It draws upon and extends the analysis of a case study conducted on gold mining operations in Thailand. The results from the case study indicated that total GHGs emissions by company A were approximately 36,886 tons carbon dioxide equivalents (tCO2e) per annual gold production capacity that meet the eligibility criteria for small-scaled clean development mechanism (CDM) projects. The electrostatic separation process was found to release the lowest amount of GHGs, whereas comminution (i.e. crushing and grinding) generated the highest GHGs emissions. By scope, the emission from purchased electricity (scope 2) is the most significant source. Opportunities for CDM projects implementation in the gold mining sector can be found in employing energy efficiency measures. Through innovation, some technical efficiency and technological development in gold processing (i.e. high pressure grinding rolls (HPGR), vertical roller mills (VRM), gravity pre-concentration and microwave heating technologies) that have the potential to reduce energy use and also lower carbon footprint of the gold mining were further discussed. The evidence reviews found that HPGR and VRM abatement technologies have shown energy and climate benefits as electricity savings and CO2 reduction of about 8-25.93 kWh/ton ore processed and 1.8-26.66 kgCO2/ton ore processed, respectively. Implications for further research and practice were finally raised.
