A Novel Approach for Beneficiation and Dewatering of Coal Fines for Indian Coal Preparation Plant
An attempt has been made to beneficiate the Indian coking coal fines by a combination of Spiral, flotation and Oleo Flotation processes. Beneficiation studies were also carried out on 0.5mm coal fines using flotation and oleo flotation by splitting at size 0.063mm.Size fraction of 0.5mm-0.063mm and -0.063mm size were treated in flotation and Oleo flotation respectively. The washability studies ...
متن کاملDewatering of coal fines using a super absorbent polymer
403 The Journal of The South African Institute of Mining and Metallurgy JULY/AUGUST 2003 Introduction Coal preparation is used to upgrade run-ofmine coal before it is utilized by the end-user, primarily electric utility power plants. According to Fonseca1, the coal preparation process reduces the amount of noncombustible mineral impurities, acid-rain precursor sulphur-bearing minerals and hazar...
متن کاملEnhancing the MTE dewatering of sewage sludge by conditioning with brown coal
Dewatering of sewage sludge is an important part of proper sludge management practice. It is becoming a more challenging issue for water industries as new regulations on sludge disposal are being imposed. In this paper, the application of mechanical thermal expression (MTE) to dewater sewage sludge and the conditioning of sludge by mixing with brown coal are investigated. Raw sludge, sludge flo...
متن کاملRecovering industrial sludge-derived slag as fine aggregate.
This study presents the result of using melting to recover both industrial sludge slag (the main constituent of which is calcium fluoride) and water works sludge slag as fine aggregate in cement. The main characteristics of both slag and cement mortars were measured to evaluate the feasibility of using slag as aggregate. In this study, the slag replacement ratios were 0, 10, 20, 30, 40, and 50%...
متن کاملInnovative Algae Dewatering Technology
Abstract This paper describes a novel technology for dewatering of bio materials, such as algae, for biofuel production and other applications. This hydrodynamic separation (HDS) technology uses customized fluid flow patterns to focus suspended particulates into a well-defined band near a side wall of a curved channel, and where they can be separated off with a suitably designed flow splitter. ...
