Mineral processing—also known as ore dressing—is a series of physical and physicochemical treatments applied to raw ore extracted from mines.
By leveraging natural differences among various minerals—such as density, magnetism, buoyancy, electrical conductivity, and surface properties—the process effectively separates valuable minerals of economic interest from useless gangue, soil, and impurities. This involves removing waste rock and harmful substances to significantly upgrade the grade of valuable metallic or non-metallic minerals. The outcome is the separation of high-purity concentrates, middlings, and tailings, thereby ensuring the ore meets the required standards for smelting, further processing, and industrial application, while simultaneously maximizing the recovery of valuable minerals and minimizing resource waste.
