Influence of Operating Variables on Flotation of High Ash Coking

Singh, Ratnakar and Sinha, S N (2005) Influence of Operating Variables on Flotation of High Ash Coking. In: International Seminar on Mineral Processing Technology(MPT-2005), January 6-8, 2005, Indian School of Mines, Dhanbad.



The paper deals with the results of flotation studies carried out on a high ash coking coal sample. The influ-ence of various operating parameters such as collector and frother dosage, pH of the pulp, pulp density, aerat- ion and agitation were studied in a wide range. The flotation performance was assessed in terms of recovery, grade, selectivity index and flotation rate constants. The flotation rate constants were computed using a modified first order rate equation. Results have been discussed based on the analysis of the flotation data.
