Abstract  |
Acid mine drainage (AMD) is the most serious environmental problem facing the Canadian mineral industry today. It results from oxidation of sulphide minerals (e.g. pyrite or pyrrhotite) contained in mine waste or mine tailings and is characterized by acid effluents rich in heavy metals that are released into the environment. A new acid remediation technology is presented, by which metallurgical residues from the aluminium extraction industry are used to construct permeable reactive barriers (PRBs) to treat acid mine effluents. This technology is very promising for treating acid mine effluents in order to decrease their harmful environmental effects |

| Abstract |
An acid mine drainage in abandoned Horobetsu mine in Hokkaido, Japan, contains arsenic and iron ions; total arsenic ca.10ppm, As(III) ca. 8.5ppm, total iron 379ppm, ferrous iron 266ppm, pH1.8. Arsenic occurs mostly as arsenite (As (III)) or arsenate (As (V)) in natural water. As(III) is more difficult to be remove than As(V), and it is necessary to oxidize As(III) to As(V) for effective removal. 5mL of the mine drainage or its filtrate through the membrane filter (pore size 0.45 mu m) were added to arsenite solutions (pH1.8) with the concentration of 5ppm. After the incubation of 30 days, As(III) was oxidized completely with the addition of the mine drainage while the oxidation did not occur with the addition of filtrate, indicating the microbial oxidation of As(III). In this paper, we have investigated the microbial oxidation of As(III) in acid water below pH2.0. |

membranes reverse osmosis ultrafiltration microfiltration desalination waste-water treatment industrial effluents |
| Abstract |
Away back in 1953 few people in the world, let alone South Africa, knew or had heard about membrane desalination, but there was an increasing awareness that electrodialysis had considerable potential for the desalination of brackish water.In South Africa the development of the new gold fields in the northern Orange Free State and the problems posed by the presence of excessive volumes of very saline mine waters stimulated interest in desalination and the CSIR* in collaboration with the mining industry became involved in the development of the electrodialysis process. By 1959 the largest brackish desalination plant in the world had been built and commissioned. South Africans were thus in the forefront of this technology, even to the extent of making the required membranes locally.Our historical review of membrane development and the applications of membrane technology in Southern Africa encompasses both pressure- and voltage-driven processes. Examples of the pressure processes are microfiltration, ultrafiltration and charged membrane ultrafiltration or nanofiltration, and finally reverse osmosis with fixed and dynamically formed membranes. The voltage-drive processes considered are electrodialysis and electrodialysis reversal. |

| Abstract |
Bestimmte Wasserpflanzen in Teichen können Metalle aus sauren Grubenwässern binden durch Adsorption, Filtration und Einlagerung in Wurzeln und Blättern. Algen und oxydierende Bakterien unterstützen diesen Reinigungsprozeß. Angaben zur Anlage der Teiche: Durchflußkapazität 20 l/min bis 38 l/min, Spülung von 18 m(exp 2) pro 4 l Durchflußmenge, Wasserhöhe 5 cm bis 10 cm, der pH-Wert des austretenden Wassers ist größer als 4,0. |

| Abstract |
Beth Energy's Mine 105W is located in Barbour County, West Virginia, near Buckhannon. The mine was opened by drifts updip into the Pittsburgh Seam in 1971 and operated until June, 1982. Most of the water which enters Mine 105W percolates down from previously mined areas in the Redstone Seam, Mine 101, which generally lies 38 feet above the Pittsburgh Seam. The quality of this water is good as it enters Mine 105W. While operating, the Mine 105W water was segregated by pumping. The bulk of the water was collected in sumps near the main area of infiltration from the Redstone Seam and was pumped to Gnatty Creek Portal where, because of the quality, it was minimally treated and discharged. The remainder of the water flowed to the original West Portal where it was occasionally treated with lime. |
