The paper shows the results of long-term field studies species composition and number bats in 8 abandoned mines Mogol-Tau mountains foothills northern slope Turkestan Mountain ranges territory Northern Tajikistan. It reveals that diversity have decreased both “winter” stationary mine “summer” ranges. At same time, Myotis blythii Tomes 1857 has remarkably increased summer. suggests these changes...

Water draining abandoned mines or mine sites is often acidic and contains relatively high concentrations of dissolved metals and sulfate. Such water (AMD) arises from the oxidative dissolution of sulfidic minerals, such as iron pyrite (FeS2), exposed by mining activities. As AMD production can occur over a very long time scale, passive remediation systems are becoming increasingly important in ...

Gold is a highly valued and volatile commodity which is subject to many external forces, such as price and availability. Global gold stocks are increasing but the supply is dwindling. Gold mining companies are always looking for novel methods to optimise extraction and processing thereby reducing operating costs and maximising profit. The extraction and processing of gold involve...

Power supply instability in the grid has been exacerbated by rapid development of new energy generation methods. Notably, large-scale storage is most practical solution to this problem. Meanwhile, China, an effective method reusing increasing number abandoned coal mines urgently required. Accordingly, building compressed air (CAES) plants along roadways can serve as a viable while repurposing t...

Investigations into the cause and control of the production of sulfuric acid in effluents of coal mines, and the effects of such effluents upon streams were begun in 1946.1 Working and abandoned mines of Western Pennsylvania alone contribute an estimated million tons of sulfuric acid per year to the drainage area of the Ohio River. A field survey of mine drainage and receiving streams was inaug...

Abstract Mines result in land use and cover (LULC) change due to degradation of natural resources establishment new infrastructure for ore extraction beneficiation. The present study was carried out to, with objectives, (1) characterize LULC (from 1975 2017) Khetri copper mine region, (2) spatial distribution pollution indices (3) spectral response elemental concentration soil groundwater using...

South Africa has the potential to be a global leader in implementing strategies targeting geochemical carbon dioxide removal (CDR) using mine tailings, utilising methods for alkalinity production and mineral carbonation. This is due hundreds of millions tonnes geochemically mineralogically suitable tailings produced annually from diamond, PGM, chrome, nickel, phosphate, copper, talc magnesite m...

The presence or absence of an oestrogen receptor-related antigen in breast tumours has been examined histochemically using a monoclonal antibody ('D59 Coffer & King, 1981). In frozen sections, fixed either by the method of Tamura et al. (1980) or in methanol, staining was apparent in 14/24 (58%) and 22/26 (85%) of the breast cancers respectively. In paraffin sections fixed in ethanol, staining ...
