  Title Use of a wetland system for treating Pb/Zn mine effluent: A case study in southern China from 1984 to 2002 Type Journal Article
  Year (down) 2004 Publication Wetlands Ecosystems in Asia: Function and Management Abbreviated Journal  
  Volume 1 Issue Pages 413-434  
  Keywords mine water treatment  
  Abstract A constructed wetland system in Guangdong Province, South of China has been used for treating Pb/Zn mine discharge since 1984. In this chapter, the performance of this system in the purification of mine discharge, metal accumulation in different ecological compartments and ecological succession within the system during the period of 1984-2002 has been reviewed. The data show that the wetland system not only effectively remove metals (mainly Pb, Zn, Cd and Cu) and total suspended solids from the mine discharge over a long period leading to significant improvement in water quality, but also gradually increase diversity and abundance of living organisms.

  Title The UK coal authority minewater-treatment scheme programme: Performance of operational systems Type Journal Article
  Year (down) 2003 Publication Jciwem Abbreviated Journal  
  Volume 17 Issue 2 Pages 117-122  
  Keywords mine water treatment  
  Abstract This paper summarises the performance of minewater-treatment schemes which are operated under the Coal Authority's National Minewater Treatment Programme. Commonly-used design criteria and performance indicators are briefly discussed, and the performance of wetland systems which are operated by the Coal Authority is reviewed. Most schemes for which data are available remove more than 90% iron, and average area-adjusted iron-removal rates range from 1.5 to 5.5 g Fe/m(2). d. These values, which are based on performance calculations, can be distorted by several factors, including the practice of maximising wetland areas to make best use of available land. Removal rates are limited by influent iron loadings, and area-adjusted iron-removal rates should be used with caution when assessing wetland performance. Sizing criteria for all types of treatment system might be refined if more detailed data become available.

  Title The design and optimisation of active mine water treatment plants Type Journal Article
  Year (down) 2003 Publication Land Contam. Reclam. Abbreviated Journal  
  Volume 11 Issue 2 Pages 273-280  
  Keywords sludge mine water treatment mine water active treatment precipitation iron manganese high density sludge sulphide Groundwater problems and environmental effects Pollution and waste management non radioactive manganese sulfide pollutant removal iron water treatment mine drainage  
  Abstract This paper provides a 'state of the art' overview of active mine water treatment. The paper discusses the process and reagent selection options commonly available to the designer of an active mine water treatment plant. Comparisons are made between each of these options, based on technical and financial criteria. The various different treatment technologies available are reviewed and comparisons made between conventional precipitation (using hydroxides, sulphides and carbonates), high density sludge processes and super-saturation precipitation. The selection of reagents (quick lime, slaked lime, sodium hydroxide, sodium carbonate, magnesium hydroxide, and proprietary chemicals) is considered and a comparison made on the basis of reagent cost, ease of use, final effluent quality and sludge settling criteria. The choice of oxidising agent (air, pure oxygen, peroxide, etc.) for conversion of ferrous to ferric iron is also considered. Whole life costs comparisons (capital, operational and decommissioning) are made between conventional hydroxide precipitation and the high density sludge process, based on the actual treatment requirements for four different mine waters.

  Title Comparison of calcite to quicklime for amending partially oxidized sulfidic mine tailings before flooding Type Journal Article
  Year (down) 2003 Publication Environ Sci Technol Abbreviated Journal  
  Volume 37 Issue 7 Pages 1408-1413  
  Keywords mine water treatment  
  Abstract Flooding partially oxidized mine tailings for the purpose of mitigating further oxidation of sulfide minerals and generation of acid drainage is generally preceded by treatment with alkaline amendments to prevent releasing previously accumulated acidity to the water cover. This work compares the ability of calcite (CaCO3) and quicklime (CaO), two common amendments, to establish and maintain pH conditions and dissolved metal concentrations within environmentally acceptable ranges over long time periods. Although higher initial pH values were obtained with quicklime, the pH of quicklime treated tailings decreased over time. This was attributed to the low buffering capacity of quicklime treated tailings and to the consumption of hydroxide ions by incongruent dissolution of water-insoluble iron oxyhydroxysulfate minerals. In contrast, the pH of tailings treated with calcite increased initially and then remained stable at pH approximate to 6.7. This pH behavior was due to the lower reactivity of iron oxyhydroxysulfates with calcite, the increased buffering capacity provided by bicarbonate ions, and the incomplete dissolution of calcite. Overall, calcite was found preferable to quicklime for maintaining long-term neutral pH conditions in the treated tailings. With the exception of zinc, acceptable dissolved metal concentrations were achieved with calcite treated tailings.

  Volume 21 Issue Pages 333-348  
  Keywords mine water treatment  
  Abstract Poland is comparatively a poor country in relation to resources of drinking water. In count per capita it is oil one of the last places in Europe. Such state forces to save resources for example by closing water circulations and also desalination of mining waters.
