Smelting is an important process in copper production to produce matte and slag which can contain 1-12% Cu. The slag can be further processed to recover the copper contaminated, but recycle of the slag concentrate reduces overall productivity and efficiency of the operation. The best solution is to minimize the Cu loss to the slag. The entrained matte droplets in copper smelting slag may originate from a few sources. The present study aims to investigate possible copper matte loss mechanisms by visualization of room temperature experiments and high-temperature examination. It is believed that the gas bubbles from the matte phase disperse the matte droplets into the slag causing entrained matte in slag. Analyses of quenched slags from an industrial operation and laboratory experiments confirmed that matte droplets in the slag are extensively associated with the gas bubbles. Water model is used to simulate the procedure and the bubble behaviors at the liquid-liquid interface are observed experimentally with a high-speed camera.
