Abstract
Mechanical excavation and the successive processes coal production are the main reason for the occurrence of fine waste coals. These wastes are normally discharged without being processed from coal washing plants. Therefore, it causes not only economic loses but also severe environmental problems. It was attempted to enrich waste coals of WLC by using physical and physico-chemical methods and the results were compared.
From the tests the optimum carbon content and the combustible recovery values were obtained as 85% and 97%, respectively, when heavy media and the coarse particle size group were chosen. From the tests with the medium particle size group using spiral and Knelson separators, combustible recovery of up to 90% was reached together with a carbon content of 80%. Moreover, a carbon content of 86.5% with a combustible recovery of 56.6% was obtained by using MGS. In the fine particle size group, the highest combustible recovery was obtained by using spiral and Knelson separators. The highest carbon content in the fine particle size group was obtained through MGS and Jameson Cell.
期刊介绍:
Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
