Article Performance Comparison of Waste Cooking Oil on Coal Slime Flotation With Sunflower Oil and Gas Oil(2023-12-31) Hacıfazlıoglu, Hasan; Arslan, Dilek SenolThis 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 wastes and are hazardous to human health and the environment, if not disposed of properly. In this study, co-disposal of the two wastes was investigated; a gas oil (petroleum derived 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 combustible recovery. Contact angle measurements were performed with 3 different oils (CSO, WSO and gas oil) by sessile drop technique to determine the hydrophobicity and surface properties of coal. Fourier-transform infrared (FTIR) spectroscopy was utilized to analyze the chemical composition of both waste oil and coal samples.

In this context, a detailed literature survey was carried out colemanite minerals. Characteristic and structural features of the colemanite samples of four different regions (Kestelek, Emet (Hisarcık, Espey), Bigadiç regions) were determined by analyzes such as X-Ray Diffraction (XRD), Inductively Coupled Plasma, ICP and Mass Spectrometry, MS (ICP-MS), Thermogravimetric and Differential thermal analysis (TG-DTA), and Fouier Transform Infrared Spectroscopy (FT-IR) methods. In line with these findings, the mineralogical, chemical and thermal properties of pure colemanite crystals were determined and the similarities and differences between the samples were revealed. © 2025 Elsevier B.V., All rights reserved.
