In a scrap processing industry, fine char is produced from the pyrolysis of shredder residue. The char is generally landfilled due to its small particle size and high ash content that make it difficult to utilize the char as a solid fuel in the electric furnace. In this study, froth flotation techniques were conducted to recover carbonaceous and remove ash content from the char. Flotation parameters such as particle size, pH, dosage of collector, frother dosage, type and dosage of surfactant were investigated.
