The refining process is a series of steps used to purify raw materials, such as metals or oil, to make them suitable for use. In metallurgy, this often involves removing impurities from ores to obtain pure metals like gold or copper. In the oil industry, refining transforms crude oil into useful products like gasoline and diesel through distillation and chemical processes. This process typically includes several stages, such as separation, conversion, and treatment. Each stage is designed to enhance the quality of the final product while minimizing waste. The refining process is essential for producing materials that meet industry standards and consumer needs.
