Geochemical and Mineralogical Characterisation of Two Contrasting Waste Rock Dumps — The INAP Waste Rock Dump Characterisation Project

2003
This paper presents the results and findings of geochemical and mineralogical testwork conducted on samples collected from waste rock dumps at two mine sites, located in South Carolina, USA (Site 1) and Sudbury Ontario, Canada (Site 2). Important aspects of the relationship between the physical and geochemical aspects of the dumps are also presented ...

Geochemistry of waste rock at dumping area

International Journal of Mining, Reclamation and Environment, 2009
Geochemical characteristics and the increase in the total reactive surface area of the sulphide-bearing rock due to weathering processes at dumping area, are expected to enhance the oxidation of sulphides, leading to the generation of acid mine drainage (AMD). The study of the changes of geochemical characteristics of sulphide-bearing rocks showed that

Geotechnical characterization of mine waste rock

2011
The determination of geotechnical charactertiscs of waste rock is essential for addressing issues of in situ hydrology and the stability of steep and high-standing dumps. Based on laboratory investigations and numerical modeling, this paper gives the geotechnical properties of a selected waste rock under saturated and unsaturated conditions.

Laboratory and field strength of mine waste rock

1983
Synopsis Laboratory testing of samples of waste rock fill at Bougainville, Papua New Guinea, has enabled the quality of the rock fill to he defined in terms of its particle size distribution. The strength of poor quality rock fill has been determined by triaxial testing and by back-analysis of observed waste dump slips, and slope stability charts have ...

Rock & Roll: Waste seperation

2000
Five hundred tonnes of glass, 1 million tonnes of plastic,14 million tonnes of building and demolition waste, 7 million tonnes of household waste, 3 million tonnes of packaging, 3.5 million tonnes of paper and board, and 300,000 old cars. All part of the annual harvest of waste materials in the Netherlands. Optimal processing is still lacking for quite
