Effect of Temperature on Coal Flotation with Waste Vegetable Oil as Collector

Abstract

In this study, the effect of pulp temperature on coal flotation was investigated. Waste vegetable oil was used as collector. Experiments were carried out at different temperatures (5, 25, 50, and 75 degrees C) and the pros and cons of each temperature for flotation performance were revealed. While flotation performance was lower in higher pulp temperatures (50 and 75 degrees C), flotation performance was found higher in lower pulp temperatures (5 and 25 degrees C). Highest combustible recovery values were obtained at 25 degrees C pulp temperature, and the lowest ash product was obtained at 75 degrees C. However, the lowest combustible recovery value was obtained in flotation at 75 degrees C.
