Controlled Oxidation Studies of Coal/Refuse Fuel Blends
A study of the controlled combustion of blends of biomass materials and coals was conducted. Crushed limestone was added to the blends as an absorbent for sulfur oxides. The samples were combusted in quartz-fiber crucibles in a forced air furnace. Combustion at different times and temperatures were …

Geoenvironmental aspects of coal refuse-fly ash blends
The separate land disposal of coal refuse and fly ash presents difficulties throughout the Appalachian region, both in terms of disposal costs per acre and in terms of its potential environmental impacts on soil, ground water, revegetation, and slope stability. The purpose of this study was to …

Immobilisation of copper, chromium and arsenic on stabilised domestic refuse
The disposal of copper-chromium-arsenic, whether in solution or in combination with wood, has the potential to become a global problem. This chemical is commonly called CCA or Tanalith, and is classed as a waterborne wood preservative. Current global production of this class of chemicals is …

Identification, Characterization, and Speciation of Rare Earth Elements in Coal Refuse
… upon the identification of REEs within coal refuse, but the phase designation and speciation is not fully understood. This investigation focuses on the characterization, speciation, and morphology of REEs within fine and coarse coal refuse. During this study, physical and chemical …

Physical and chemical properties of coarse coal refuse from Southwest Virginia
Coarse coal refuse is difficult to reclaim due to high potential acidity and coarse fragment content, low water holding capacity, low fertility, and other problems. Little is known about coal refuse properties, particularly as they relate to revegetation potential. This study was undertaken to …

Geotechnical characterization of coal refuse for use as a backfill material
… Backfilling can also be used as a means of mine refuse disposal, provided the refuse is a suitable fill material. A Iiterature review has been made of the various backfilling practices and stowing materials that have been used in both underground hardrock and coal mines. The mechanics of fill …

PERCEPTIONS OF ABILITY TO REFUSE SEX AMONG SINGLE WOMEN IN URBAN CAMEROON
… that influence young women's ability to refuse sex with a man who has paid her school fees and a man who has power over her such as a teacher or employer. I use the 2002 Cameroon Adolescent Reproductive Health Survey, which contains information on a randomly selected sample of youth, aged …

Concentration and Recovery of Rare Earth Elements from Eastern US Coal Refuse
… and extraction of REEs from fine coal refuse derived from various preparation plants in the Appalachian coal basin of the United States. Initial efforts in this research focused on the identification and characterization of REEs in various fine coal refuse streams from nine distinct …

Paradigms of refuse: waste abjection and rejection in contemporary Italian literature and cinema
“Paradigms of Refuse” explores Italy and the Mediterranean as landscapes of crisis, sites where environmental threats, social inequalities, and geopolitical turmoil converge. These landscapes are increasingly being transformed into dumping sites where the material as well as the human excess of our …

The effect of sewage sludge co-disposal and leachate recycling on refuse stabilization
In the past sanitary landfill sites for solid waste disposal were regarded simply as containment sites so that the waste contents were isolated from the population. Various degrees of effort were made to reduce the impact of the waste in and around the site - in some cases none in other cases …

Evaluation of Leachate Chemistry from Coal Refuse Blended and Layered with Fly Ash
… has been studied as a liming agent within coal refuse fills to reclaim acid-forming refuse. Previous studies focused on bulk blending ash with acid-forming (pyritic) refuse. A better representation of field conditions is a "pancake layer" of ash above the refuse. A column study was initiated to …

Modelling and characterisation of the pyrolysis of secondary refuse fuel briquettes and biomass materials
… waste, and the pyrolytic behaviour of secondary refuse fuel (SRF) briquettes and biomass-derived fuels is the starting point for the process. The purpose of this study was to evaluate the pyrolytic characteristics of SRF briquettes and biomass materials, suggest a kinetic model for simulating the …

Influence of fly ash and other treatments on acid mine drainage from coal refuse
Most Appalachian coal refuse materials contain significant amounts of pyritic sulfur and are likely to produce acid mine drainage (AMD). A column technique was designed and implemented to evaluate the effects of various AMD mitigation treatments including fly ash, topsoil, lime, and rock-P. Two …

The influence of fly ash additions on acid mine drainage production from coarse coal refuse
… alkaline fly ash with acid forming coal refuse may present a disposal option that aids in the control of acid mine drainage. A preliminary column leaching study examined the leachate quality from acid-forming coal refuse:fly ash blends. Coal refuse (2.2 % total-S), and two refuse:fly ash …

Effect of Leaching Scale on Prediction of Total Dissolved Solids Release from Coal Mine Spoils and Refuse
… using one coal mine spoil and two coarse coal refuse materials. A non-acidic mine spoil sample from SW Virginia (crushed to ≤ 1.25 cm) was placed into PVC columns (~10 cm x 40 cm) in the laboratory and leached unsaturated with simulated acidic rainfall. The same spoil was also placed into …
