  Title Calcification treatment of mine drainage and depositional formula of heavy metals Type Journal Article
  Year 2000 Publication Chikyu Kagaku = Earth Science Abbreviated Journal  
  Volume 54 Issue 5 Pages 328-336  
  Keywords acid mine drainage Asia calcification deposition ettringite Far East heavy metals Ishikawa Japan Japan lime Ogoya Mine pollution sulfates waste water water treatment 22, Environmental geology  
  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.

  Title The Golden Cross Mine water management system Type Journal Article
  Year 1994 Publication New Zealand Mining Abbreviated Journal  
  Volume 14 Issue Pages 15-21  
  Keywords Australasia Coromandel Peninsula cyanides gold ores Golden Cross Mine metal ores mines New Zealand North Island tailings Waihi New Zealand waste water water management water treatment 30, Engineering geology  
  Abstract Because of its location in the sensitive Coromandel Peninsula, strict water management and environmental requirements had to be met on the Golden Cross Mine Project. This led to the development of new technologies for cyanide recovery and the adoption of advanced water management and water treatment systems. This paper discusses the water management and treatment system adopted for contaminated water at Golden Cross. While permit discharge levels must be and are met for mine discharge waters, the ultimate success of the water management system is demonstrated by the results downstream; biological surveys show no changes to the resident aquatic life in the river.

  Title Mine drainage treatment and ferrite sludge application Type Journal Article
  Year 1991 Publication NEC Technical Journal Abbreviated Journal  
  Volume 44 Issue 5 Pages 4-16  
  Keywords ferrite applications mining water treatment mine drainage treatment waste water treatment ions metal recovery catalysts environmental problems solution ferrite sludge application iron oxidation bacteria ferrite formation process mine drainage Matsuo Mine magnetic marking materials magnetic fluid metal separation semiactive magnetic damper batteries fish gathering cement tracer Electrical and Electronic Engineering Manufacturing and Production  
  Abstract The `ferrite process' is an excellent method for treating waste water containing iron and arsenic, but cannot be directly applied to mine drainage where silicon and aluminum ions are present, because they strongly inhibit ferrite formation. As a result of the development of related technologies such as the elimination of silicon, the concentration of iron, and the oxidation of ferrous ions using iron-oxidation bacteria, a new ferrite formation process has been developed and applied to the mine drainage of the Matsuo Mine. The paper discusses the application of the ferrite sludge to magnetic marking materials, magnetic fluid for metal separation and recovery, and the semiactive magnetic damper is described. The related technologies which will be expected to play an important role in solving the environmental problems are also described. These technologies will change the ferrite sludge to beneficial materials, which can be used for carbon dioxide decomposing catalysts, reuse of dry batteries, fish gathering blocks, and cement tracer for ground improvement
