Groundwater in the Latrobe Valley in the Gippsland Basin of southeast Australia is important for domestic, agricultural and industrial uses. This sedimentary basin contains a number of aquifers that are used for water supply, dewatered for open pit coal mining, and which are potentially influenced by off-shore oil and gas production.

Smith Mining Camps. Prospect Scale Exploration Both U and Au can be also explored for at the prospect scale using hydrogeochemistry. For Au, other elements such as Mo, W and Rb may also be useful, in addition to Au, Ag, As. Both VHMS and Ni sulfide mineralisation is more effectively delineated at prospect scale, due to the small size

Combining environmental isotope analysis with principal component analysis can be an effective method to discriminate the inflows and sources of contamination in mining-affected watersheds. This paper presents a field-scale study conducted at an acid mine drainage (AMD)-contaminated site adjacent to …

1. Introduction. 1.1. General types of mine drainage. Mine drainage, i.e. waters affected by mining and mineral processing, can be acidic, circumneutral, basic, dilute, mineralized, and saline. This paper provides an overview of the wide varieties of mine water chemistry and the processes that form them.

In 2016, 25% of groundwater management areas in Australia were considered to be over-allocated, and there are examples where limits have been reduced due to impact of drawdown on ecosystems.

Research on hydrogeochemistry for mineral exploration for inland Australia includes development of weathering models and extensive mine-scale and regional …

The Jinding Pb-Zn deposit in Yunnan is rich in cadmium,and mining activity facilitates releasing of cadmium into the aquatic ecosystem.Water in the mining district contains elevated cadmium concentration,being 50-100 times higher than that of natural water.Cadmium concentrations in the local catchment range from 15 to 30 μ g/L,and …

Mining activities have long-term impacts on the groundwater of surrounding areas and deserve in-depth analysis and study. Herein, the geochemical mechanisms of acid mine drainage (AMD)-affected groundwaters were examined, and groundwater quality was assessed through water quality indices. 15 water samples from 7 domestic and 4 …

Further information could be provided by studies of the origin and hydrogeochemistry of AMD in mining areas where water samples can be collected from inside mining levels and surface sites. The Yatani mine area in central Honshu Island, Japan, was selected for this study. The area includes a closed non-ferrous sulfide mine …

To study the influence of coal mining on the hydrogeochemical process of groundwater, taking Guqiao Coal Mine, Huainan coalfield as an example, 32 groundwater and 4 surface water samples, 4 mine drainage samples and atmospheric precipitation were collected in the mine, and the hydrochemical type, TDS, and TH were analyzed using …

Mining industry experts in Australia suggest automation of mining operations will lead to better productivity and safer working conditions without threatening the jobs of mining workers.

The impact of past mining activities on the quality of groundwater and surface water has been investigated in the mining district of La Carolina (southern Spain, province of Jaén), a region characterised by the presence of mineralisations of Pb–Ag, Cu and Fe sulphides and Ba sulphates. The chemistry of waters from flooded galleries, shafts and …

A natural "Hydrogen System" has been assessed for Western Australia in this paper. • Interactions between iron-rich minerals and water are a possible source of H …

Government agencies such as Geoscience Australia, NSW Department of Industry (Water) and the Geological Survey of NSW (GSNSW); research organisations like the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and universities; and landholders routinely take water samples.

Abstract. Acid mine drainage (AMD) is created when iron–sulfur compounds come into contact with atmospheric oxygen and water. Through a series of chemical and biochemical reactions, a solution with low pH, high mineral acidity, and elevated dissolved metal (e.g. iron, aluminum, magnesium) concentrations is produced.
