Özet
This study explores the potential use of waste cooking sunflower oil (WSO) as an eco-friendly collector for coal slime flotation. WSO and coal slime are both waste materials and can be hazardous to human health and the environment, if not disposed of properly. In this study, co-disposal of the two wastes was investigated; a kerosene (petroleum de-rived oil) and crude sunflower oil (CSO) were used for collector efficiency comparisons. This study also presents a green, low-cost and environmentally friendly alternative. Kinetic flotation tests were carried out to study the flotation selectivity, flammability and com-bustible recovery. Contact angle measurements were performed with 3 different oils (CSO, WSO and kerosene) by sessile drop method to determine the hydrophobicity and surface properties of coal. Fourier-transform infrared (FTIR) spectroscopy was utilized to analyze for the chemical composition of both WSO and slime coal samples
