We use mathematical optimization to determine a production schedule (i.e., a schedule of extraction and subsequent filling of the voids) for a complex underground mine in Ireland. The goal of the mining operation is to maximize metal production over the life of the mine, subject to constraints on maximum monthly extraction and backfilling quantities, maximum and minimum monthly metal production...

Acid mine drainage (AMD) is one of most significant environmental challenges facing the mining industry worldwide. It occurs as a result of natural oxidation of sulphide minerals contained in mining wastes at operating and closed/decommissioned mine sites. AMD may adversely impact the surface water and groundwater quality and land use due to its typical low pH, high acidity and elevated concent...

Sulfide oxidation is a common phenomenon associated with many mined ore bodies and extracted or processed waste. Where the products of these chemical reactions can enter a water body the result is often a reduction in water quality through the increase of acidity, metals and dissolved salts. Due to an attributed lower environmental impact the release of sulfate has received little attention in ...

This study aimed to assess the composition, seasonality, and abundance of phytoplankton community a Boron (B) mine effluent storage reservoir, Çamköy Reservoir, Bal?kesir, Turkey. For this purpose, certain physicochemical parameters were sampled seasonally between April 2015 January 2016. B concentrations ranged from 554 mg L-1 689 L-1. A total 39 taxa identified during study. The percent compo...

The role of indigenous and non-indigenous arbuscular mycorrhizal fungi (AMF) on As uptake by Plantago lanceolata L. growing on substrate originating from mine waste rich in As was assessed in a pot experiment. P. lanceolata inoculated with AMF had higher shoot and root biomass and lower concentrations of As in roots than the non-inoculated plants. There were significant differences in As concen...

Waste ore samples (pH 3.0) were collected at an acid mine drainage (AMD) site in Anhui, China. The present acidophilic microbial community in the waste ore was studied with 16S rRNA gene clone library and denaturing gradient gel electrophoresis (DGGE). Eighteen different clones were identified and affiliated with Actinobacteria, low G + C Gram-positives, Thermomicrobia, Acidobacteria, Proteobac...

A total of 400 samples were collected from different thermogenic habitats such as nests of birds, decomposing litter, soils from furnace area, cattle dung, zoo dump, industrial waste, vegetable market compost, mushroom compost, horse dung, municipal waste, chicken manure and coal mine soils of Godavari Khani (Karimnagar) and Bhoopalpally (Warangal) group of mines in Andhra Pradesh. From which 4...
