Concentration of Zonguldak hardcoal by flotation: Comparison of classical (kerosene) and vegetable oil (sesame oil)

Year 2019, Volume: 2 Issue: 4, 119 - 126, 30.12.2019

Abstract

Flotation is a widely used physicochemical separation method for the benefication of fine coals. In this study, the use of vegetable oil(sesame oil)an alternative to kerosene has been investigated for flotation of Zonguldak Hardcoal. The effects of collector concentration, pH, flotation time, pulp density, impeller speed and frother concentration on combustible recovery, ash reduction and efficiency index were studied and optimum conditions were determined for hardcoal. As can be seen from these results, vegetable oil (sesame oil) for Zonguldak Hardcoal showed high collecting ability as an alternative to the petrol such as kerosene. In other words, it was found out that vegetable oils could be used as collector in coal flotation.
