Abstract |
One of the serious problem faced by the mining industry is the disposal of acid mine drainage in view of it's harmful effects on receiving water bodies.Studies were conducted at Churcha underground mines of Colleries of South Eastern Coal Fields (CoalIndia Ltd) on the acidic mine waters with a view to evolve effective treatment system. The results of treatability studies alongwith viable treatment options are discussed in the paper. |

Abstract |
Responsible mining companies have done much to redress the environmental damage of earlier technologies and continue to do more. In the Sudbury Basin, one of the most important mining areas in the world, both Inco Limited and Falconbridge Limited, two of the largest nickel producers, have significantly decreased sulphur dioxide emissions in the last 40 years from substantially 100% to about 10% or less of the sulphur in the ore; decreased water effluents by recycling; treated effluents to comply with government regulations; revegetated mine rock and surface tailings deposits and rehabilitated landscapes in the surrounding communities. Inco and Falconbridge continue to develop improved means for environmentally sound handling of all wastes including recycling and to reclaim land at abandoned mine sites. They have developed and implemented environmental policies and codes of practice, not only to comply with regulations, but to anticipate them. The mining industry recognizes the need for regulation to protect human health and the environment. Existing regulations are based on a hazard assessment approach. A more realistic, pragmatic and cost-effective basis for regulation is risk management. This relates any documented effects to measured exposures and recognizes the need for exposure levels low enough that incidence of adverse health effects is as low as in the surrounding ecosystem. |

Abstract |
In Alberta, oil sands bitumen is utilized for synthetic crude oil (SCO) production by surface mining, bitumen extraction followed by primary (coking) and secondary (catalytic hydro-treating) upgrading processes. SCO is further refined in specially designed or slightly modified conventional refineries into transportation fuels. Oil sands tailings, composed of water, sands, silt, clay and residual bitumen, is produced as a byproduct of the bitumen extraction process. The tailings have poor consolidation and Water release characteristics. For twenty years, significant research has been performed to improve the consolidation and water release characteristics of the tailings. Several processes were developed for the management of oil sands tailings, resulting in different recovered water characteristics, consolidation rates and consolidated solid characteristics. These processes may affect the performance of the overall plant operations. Apex Engineering Inc. (AEI) has been developing a process for, thesame purpose. In this process oil sands tailings are treated with Ca(OH)(2) lime and CO2 and thickened using a suitable thickener. The combination of chemical treatment and the use of a thickener results in the release of process water in short retention times without accumulation of any ions in the recovered water. This makes it possible to recycle the recovered water, probably after a chemical treatment, as warm as possible, which improves the thermal efficiency of the extraction process. The AEI Process can be applied in many different fashions for the management of different fractions of the tailings effluent, depending on the overall plant operating priorities. |

Abstract |
A simulation model is developed of the efficiency and economics of an application of ecotechnology – using a created wetland to receive and treat coal mine drainage. The model examines the role of loading rates of iron on treatment efficiencies and the economic costs of wetland versus conventional treatment of mine drainage. It is calibrated with data from an Ohio wetland site and verified from multi-site data from Tennessee and Alabama. The model predicts that iron removal is closely tied to loading rates and that the cost of wetland treatment is less than that of conventional for iron loading rates of approximately 20-25 g Fe m “SUP -2” day “SUP -1” and removal efficiencies less than 85%. A wetland to achieve these conditions would cost approximately US$50 000 per year according to the model. When higher loading rates exist and higher efficiencies are needed, wetland systems are more costly than conventional treatment. -Authors |
