Abstract |
Depositional formula of heavy metals after disposal of the mine drainage from the Ogoya Mine in Ishikawa Prefecture, Japan, was mineralogically investigated. Strong acidic wastewater (pH 3.5) from pithead of the mine contains high concentration of heavy metals. In this mine, neutralizing coagulation treatment is going on by slaked lime (calcium hydroxides: Ca(OH) (sub 2) ). Core samples were collected at disposal pond to which the treated wastewater flows. The core samples were divided into 44 layers based on the color variation. The mineralogical and chemical compositions of each layer were analyzed by an X-ray powder diffractometer (XRD), an energy dispersive X-ray fluorescence analyzer (ED-XRF) and a NCS elemental analyzer. The upper parts are rich in brown colored layers, whereas discolored are the deeper parts. The color variation is relevant to Fe concentration. Brown colored core sections are composed of abundant hydrous ferric oxides with heavy metals, such as Cu, Zn, and Cd. On the other hand, S concentration gradually increases with depth. XRD data indicated that calcite decreases with increasing depth, and ettringite is produced at the deeper parts. Cd concentration shows similar vertical profile to those of calcite and ettringite. The results revealed that hydrous ferric oxides, calcite and ettringite are formed on deposition, whereby incorporating the heavy metals. |

Abstract |
Acid mine drainage (AMD) is one of the most serious environmental problems in the metal-mining industry. AMD is formed by the chemical and bacterial oxidation of sulphide minerals, and it is characterized by low pH values and high sulphate and metals content. The most common method to treat AMD is chemical neutralization. The chemical treatment requires high capital and operating costs and its use is problematic at the closed mines sites. Outokumpu has studied and used sulphate reducing bacteria (SRB) as an alternative method for the treatment of AMD. SRB existing in many natural anaerobic aqueous environments can reduce sulphate to sulphide which precipitates metals as extremely insoluble metal sulphides. Full scale experiments were begun in summer 1995 in the Ruostesuo open pit (depth 46 m) by adding liquid manure as a source of bacteria and press-juice as a growth substrate. The average Zn content of the whole column has decreased from 3,5 mg/l to 0,8 mg/l and below 25 m zinc is 0 mg/l. Similar results have been reached with nickel in the Kotalahti old nickel mine, where bacteria were brought in 1996. We have found that the same bacterial mechanism acts in peat-limestone filters, which Outokumpu has built at several mine sites since 1993. |
