Повний текст джерелаThe processes involved in coal preparation generate harmful effects to the environment, mainly due to the quantity and nature of the wastes that are generated. These tailings generally called pyritic, not even showing high content of pyrite are an acid material, harmful to the environment. These tailings are usually disposed of in tailings dams. Froth flotation will be important as a coal preparation process to recover these ultrafine particles. The tailings, studied in this work come from a process involving dense medium cyclones and spirals. They have an ash content of 56% and a calorific value of 5,800 BTU / lb, the sulfur content is 1.2%. In terms of size the material is considered as ultrafine as 63% is less than 0.014 mm. The coal matter content of these tails is easily recovered by froth flotation, as evidenced in this work. It is possible to recover 74% of the coal matter and to obtain a product with 7.3% ash and calorific value of 14,225 BTU / lb in dry basis.

Повний текст джерелаCoal tailings are produced as a waste product from washing the fine < 2 mm fraction of mined coal to add value to the saleable product. After washing, slurried tailings are pumped to holding dams for disposal and desiccation. Once full the core of these dams dry slowly limiting vehicular access for reprocessing or rehabilitation works. In areas where evaporation exceeds rainfall, a dry surface crust, susceptible to generating wind blown dust, develops during this desiccation phase. A revegetation strategy involving establishing vegetation directly on coal tailings was therefore developed, to reduce wind blown dust hazards whilst maintaining the potential for later coal extraction. The field studies for the project were depth. In the wetland plant available water was adequate for plant growth but the material was poorly aerated where moisture content was high. ... This thesis demonstrated the establishment of salt tolerant vegetation was possible on tailings dam number three at Saraji Mine and, therefore, revegetation with the view of minimising dust and maintaining access was feasible. Treatments that facilitated vegetation establishment in the field were those that decreased salinity and increased plant available water (mulching and irrigation). Nitrogen and phosphorus fertiliser additions were shown to be necessary in the glasshouse. Given that low plant available water and high salinity were the major limitations plant growth, provided follow up fertiliser is applied, trees and deep rooted vegetation should continue to survive and grow once their roots are have developed sufficiently to access the higher moisture/lower salinity sub -surface tailings. With increased vegetative biomass, the volume of leaf litter produced and dropped onto the tailing surface would increase and "self mulching" could occur. Further monitoring to investigate the longer term "self mulching" potential, C. glauca water usage rates and changes in species composition are recommended.
