Figure 4 depicts a site-specific 3D model that was developed to integrate the rehabilitation of three waste rock dumps and to design a surface water management plan. Where available, cover system materials are fine grained or dispersive and armouring should be . Geochemical and Mineralogical Characterisation of Two Contrasting Waste Rock Dumps — The INAP Waste Rock Dump Characterisation Project A B Tran1,S Miller1,D J Williams2,P Fines3and G W Wilson3 ABSTRACT This paper presents the results and findings of geochemical and mineralogical testwork conducted on samples collected from waste rock dumps at.
Acid rock drainage from sulphide bearing waste rock dumps is the most serious environmental liability in the mining industry; believed to be $ billion for million tonnes of waste rock in Canada alone (Feasby et al., ). The understanding of the characteristics and quantity of water flow through waste rock has become by: 3. Characterization and monitoring of waste rock can help you to understand the week zones that allow meteoric waters to enter and transport mine drainage. In many situations, such as from metal and coal waste, significant amounts of pyrite will cause the waste to go acidic, which further enhances the transport of heavy metals into the.

Some of the key factors and the measurement techniques that are used to provide insight into the potential long-term impacts from waste rock dumps are as outline below. L P Peak load or concentration of pollutants in drainage from the pile. L R Environmentally acceptable load or concentration of pollutants. t L. waste rock dumps. The limited amount of quantitative data has always precluded the formulation of a theoretical framework. Therefore, there is an exigent need to develop a research protocol for hydrological characterization of unsaturated waste rock dumps. This paper presents the hydrological characteristics of a.

Early years of mining, waste rock is being disposed in sidehill waste dumps, after which waste will be placed in mined-out areas of the pit as well as waste dumps at higher elevations.
To develop a large, relatively level dump area to the west, it was necessary to place waste in a steep-sided canyon containing Y Creek. The Svartliden Gold Project has developed a complex design for waste rock dumps on the site. The design proposes encapsulation of potentially acid-forming material as cells within un-reactive.
Environmental Engineering: Sewage Disposal And Air Pollution Engineering (Volume – 2) explains to the reader in detail the techniques related to the treatment of wastewater with reference to water pollution. It also discusses the disposal of solid wastes including hazardous radioactive and bio-medical wastes covering the topic of land pollution.
Construction in lifts depends on the geotechnical properties of dump material, cost of haulage, ease of final grading, etc. Surface slope of top of the dump depends on runo-ff of water, drainage and safety. The control of runoff water and drain recharge is also very important in design of - mine waste dump.
Dumps of waste rock are composed of sand-sized particles to large boulders and have less potential to generate polluting drainage waters than tailings. The latter are fine grain wastes generated during the separation of target metal minerals from others in milled ores by froth flotation [ 1 ].Cited by: Moreover, frequently, minerals such as pyrite, talc and chlorite present in the waste rock materials release hydroxides and inorganic salts such as Ca SO4and MgSO4which are mobilised by infiltrating water and are released as seepage at the toe of the Size: 3MB.
The oxidation of sulfide minerals within waste-rock dumps can lead to poor-quality drainage called acid mine drainage (AMD), which presents an environmental risk and a financial liability for mining companies (Amos et al., ).
AMD is highly toxic, and even short-term exposure to AMD can become fatal for any type of living organism. 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 num erical modeling, this paper gives the geotechnical properties of a selected waste rock under saturated and unsaturated Size: KB.

Coal reject materials will be derived from the processing of ROM coal at the onsite coal handling and preparation plants (CHPPs). United States Environmental Protection Agency Wastewater Technology Fact Sheet Rock Media Polishing Filter for Lagoons DESCRIPTION Rock filters are often used to remove algae from lagoon effluents.
These systems consist of submerged beds of rocks, 75 to mm (3 to 8 in) in size, through which lagoon effluent is passed horizontally or vertically. Waste rock dump construction and link to AMD seepage risks Construction of waste dumps is mainly based on one of the following methods; end-tipping, paddock dumping, push-dumping, or Size: 1MB.
There are two waste dumps in close proximity to the two open pit mining operations. The paper covers the slope stability analysis of the active dump as mining expands and the dump develops further.
A phased rehabilitation programme will be implemented on the inactive dump. A layout of the open pits and the waste dumps is shown in Figure Size: KB. waste produced vary depending on the ore-deposit and host-rock mineralogy but also because of differences in ore-processing techniques (Blowes, et al., ).

Geological issues in Waste Disposal, Forestry and Engineering Waste disposal From a geological point of view the most important thing about waste disposal is the isolation of the waste, and anything that might leach out of it, from the rest of the environment - particularly from surface and ground waters.
