Metallurgy industry
The metallurgical industry refers to the industrial sector that mines, selects, sinters, smelts and processes metal ores into metal materials. Divided into: (1) ferrous metallurgical industry, that is, the industrial sector that produces iron, chromium, manganese and their alloys, which mainly provides raw materials for modern industry, transportation, infrastructure and military equipment; (2) nonferrous metallurgical industry, that is, the production Metal refining industry sectors of non-ferrous metals, such as copper smelting industry, aluminum industry, lead-zinc industry, nickel-cobalt industry, tin smelting industry, precious metal industry, rare metal industry and other departments.

Power Industry
Electric power industry (electric power industry) is the conversion of primary energy such as coal, oil, natural gas, nuclear fuel, water energy, ocean energy, wind energy, solar energy, biomass energy, etc. The industrial sector that supplies users with energy. The industrial sector that produces, transmits and distributes electrical energy. Including power generation, power transmission, power transformation, power distribution and other links. The production process and consumption process of electric energy are carried out at the same time, which can neither be interrupted nor stored, and need to be dispatched and distributed uniformly. The electric power industry provides basic driving force for industry and other sectors of the national economy. Subsequently, a number of large and medium-sized hydropower stations have been built in areas where conditions permit, which are the leading sectors of national economic development.
