Waste Characteristics In Surface Mining

  • Coal Mining and Production IFC

    waste streams: fine materials that are discharged as a slurry to a tailings impoundment, and coarse material (typically greater than 05 millimeters) that is hauled away as a solid waste Waste Characteristics The main impacts of surface mining are, in general, massive disturbances of large areas of land and possible disruption of surface andcharacteristics of each mining operation and associated waste material, in combination with varied environmental features of the sites Any proposed mining project must be evaluated in terms of the specific nature of the anticipated waste materials and its site characteristics in order to develop an effective waste management designAN OVERVIEW OF MINING WASTE MANAGEMENTWaste Characteristics Key impacts of surface mining are typically massive disturbances of large areas of land and possible disruption of surface and groundwater patterns In some surface mines, the generation of acid mine drainage (AMD) is a major problem Other significant impacts include fugitive dust and disposal of overburden/waste rockCoal Mining and Production MIGA

  • Base Metal and Iron Ore Mining IFC

    Waste Characteristics The volume of solid waste generated, including tailings from processing, is one of the main pollution concerns in the mining industry Removal of overburden to access the ore can pose major problems in storage and reclamation The overburden (wastetoore) ratio for surface mining of metal ores generally ranges from 2:1The article presents the characteristics of waste produced as a result of natural dimension stone processing and the structure of the waste production process Solid stone scraps and sludge were distinguished On the basis of the performed analyses, it was shown that stone waste constitutes 10–35% in relation to the quantity of the processedEnergies | Free FullText | Characteristics of WasteLarge amounts of waste rock are produced from surface mining operations, such as openpit copper, phosphate, uranium, iron, and taconite mines Small amounts are generated from underground mining Waste rock generally consists of coarse, crushed, or blocky material covering a range of sizes, from very large boulders or blocks to fine sandsizeUser Guidelines for Waste and Byproduct Materials in

  • Abandoned Mine Site Characterization and Cleanup

    The Abandoned Mine Site Characterization and Cleanup Handbook (Handbook) is the result of the collective efforts and contributions of a number of individuals During the earliest days of Handbook development, Mike Bishop of EPA Region 8 lead the effort to develop a Superfund Mine Waste Reference Document for EPA project managers working on mineA surface mine contains pits with mineral endowed rock (or ore) We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) This ore can include metals such as iron, copper, coal and gold There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removalEquipment Selection for Surface Mining: A ReviewTo understand the impacts of landscape characteristics on water quality in mine wastelocated watersheds, we conducted a case study in the TriState Mining District which is located in the conjunction of three states (Missouri, Kansas and Oklahoma) Severe heavy metal pollution exists in that area resulting from historical mining activitiesRelating landscape characteristics to nonpoint source

    Hardrock mining is a largescale industrial activity that takes place in the natural environment, potentially disturbing large amounts of material and land area Hardrock mining generates large volumes of mining waste because of the high wastetowaste rock dumps or spoil piles, at the completion of mining, which minimise erosion and environmental impact offsite To successfully incorporate landform designs in planning it is useful to predict the surface stability of the final landform using erosion and landform evolution modelling techniques (Evans et al 1998)ENVIRONMENTAL IMPACT OF MINING Erosion andNote: The Mining Waste Directive (2006/21/EC) uses the definition of hazardous waste References in this document to ‘directive waste’ includes waste within the scope of the Mining Waste Directive Step 2: identify the code or codes that may apply to the waste The second step is to identify how the waste is classified in the List of WasteWaste Classification GOVUK
