Title Study of comprehensive retrieval utilization and the treatment of acid mine wastewater Type Journal Article
Year 1996 Publication Zhongnan Gongye Daxue Xuebao = Journal of Central South University of Technology Abbreviated Journal
Volume 27 Issue 4 Pages 432-435

Abstract Impact of precipitating on removing harmful metal ion in the acid mine wastewater with pH neutralizer and sulfide was studied. The possible way of retrieving heavy metal ion in wastewater was probed. The techniques for lime carbonate to reject iron for hydrogen sulfide to precipitate copper and for zinc-lime cream neutralization flocculation to treat, mine acid wastewater were chosen. The final water quality may reach national effluent standard; the copper content was 32% in the sulfide slag.

Title Ecology and the problems of rehabilitating wastes from mineral extraction Type Journal Article

Abstract Environmental problems which may be associated with mineral extraction are: (a) the visual ugliness of open pits, waste tips, and working mess; (b) the nuisance of wind- and water-borne dusts; (c) the health hazards to wildlife, crops, livestock and man of locally increased environmental burdens of potentially toxic metals (e.g. Pb, Cd, As, Zn, Cu, Ni) derived from wind- and water-borne mine dusts and smelter smokes; (d) the safety hazards of surface subsidence and tip-slippage from deep-mining. All these disamenities can be cured or reduced by the reclamation process which involves a blend of socio-economic, legal, planning, civil engineering and biological expertise devoted to development planning, site purchase, land clearance, land forming, stabilization, drainage and revegetation of the affected site

Keywords water pollution biological Sulphate removal technology sulphate acidity metals treatment technique
Abstract Mining is implicated as a significant contributor to water pollution, the prime reason being, that pyrites oxidize to sulphuric acid when exposed to air and water. Mine effluents, often containing sulphate, acidity and metals, should be treated to render it suitable for re-use in the mining industry, for irrigation of crops or for discharge in water bodies. This study describes the removal of all three mentioned pollutants in mine effluents, from different origins, containing different concentrations of various metals. The objectives were achieved, applying the biological sulphate removal technology, using ethanol as the carbon and energy source. It was shown that diluting the mine effluent with the effluent from the biological treatment, the pH increased due to the alkalinity in the treated water while the metals precipitated with the produced sulphide. When this treatment regime was changed and the mine water was fed undiluted, it was found that the metals stimulated the methanogenic bacteria (MB) as trace elements. This resulted in a high COD utilization of the MB, such that too little COD was available for the SRB. Metal removal in all three studies was observed and in most instances the metals were eliminated to the required disposal concentration.

Title Hydrogeochemistry and treatment of acid mine drainage in southern China Type Book Chapter
Year 1993 Publication Proceedings of the Annual National Meeting – American Society for Surface Mining and Reclamation, vol.10 Abbreviated Journal
Volume Issue Pages 277-283
Keywords acid mine drainage Asia bacteria chemical reactions China coal mines ecology Far East geochemistry hydrochemistry Jiangxi China lime mines oxidation pH pollution sulfides surface water trace elements water quality 22 Environmental geology 02B Hydrochemistry
Abstract Coal mines and various sulfide ore deposits are widely distributed in Southern China. Acid mine drainage associated with coal and metal sulfide deposits affects water quality in some mined areas of Southern China. Mining operations accelerate this natural deterioration of water quality by exposing greater surface areas of reactive minerals to the weathering effects of the atmosphere, hydrosphere, and biosphere. Some approaches to reduce the effects of acid mine drainage on water quality are adopted, and they can be divided into two aspects: (a) Man-made control technology based on long-term monitoring of acid mine drainage; and, (b) Neutralization of acidity through the addition of lime. It is important that metals in the waste water are removed in the process of neutralization. A new method for calculating neutralization dosage is applied. It is demonstrated that the calculated value is approximately equal to the actual required value.
