In the mining and mining industries, the cleaning of oil slicks on water surfaces has always been a challenging task. Especially when mechanical equipment fails, it is often accompanied by failures and leaks in hydraulic devices, engines, fuel tanks, oil pipelines, etc. The generated waste oil flows into the mining sump through the mining drainage system. This part of the water is used in mining and dust suppression, and enters the processes of ore dressing, smelting, etc. through production return water. It may also cause important damage to the ecological environment through losses, affecting the quality of the water environment and the balance of the mining production system.
