Metallurgical extraction processes and methods according to classification can be divided into pyrometallurgical, hydrometallurgical and electric metallurgy three categories. Some people also attribute electro-metallurgy to the category of pyrometallurgy.

I. Pyrometallurgy (pyromatallurgy)

Pyrometallurgy refers to the process of reducing ore, oxidizing and melting ore and melting metal and alloy at high temperature. The process of pyrometallurgy generally involves the main processes of raw material preparation ( mineralization , sintering, pelleting, roasting, etc.), smelting process and refining process. It is the main method of extraction metallurgy, the current large-scale iron and steel smelting industry, the major non-ferrous metal smelting and certain rare metals extraction are metallurgically fire method of production.

Second, hydrometallurgy (hydrometallurgy)

Hydrometallurgy uses a liquid solvent, usually an inorganic aqueous solution or an organic solvent, to leaching, separating and extracting metals and their compounds. The hydrometallurgical process mainly includes processes such as leaching, solid-liquid separation, solution purification and enrichment, and preparation of products from solution. At present, hydrometallurgy is mainly used for the extraction of non-ferrous metals, rare metals and precious metals, and the application range is also expanding.

Third, electro metallurgy (electro metallurgy)

Electrometallurgy refers to the process of extracting and refining metals from ore or other raw materials using electrical energy. For example, molten salt electrolysis of aluminum, steel smelting electric arc furnace, electroslag remelting.

The above-mentioned extraction metallurgy processes have their own characteristics and corresponding scope of application, but they also have certain limitations. Currently, the situation facing metallurgy extraction is

(1) The useful metal mining grade of ore raw materials generally declines, and the mineral composition in the ore is more complicated;

(2) The requirements for the variety, quality and purity of product metals and their compounds are increasing;

(3) The world famous countries have stricter requirements for eliminating pollution and ecological environment protection.

The selection and combination of modern extraction metallurgy large-scale production process depends mainly on the characteristics of the ore raw materials to be processed, the types of metals to be recycled and the requirements for product quality, and also depend on relevant technical and economic indicators and geographical conditions, such as processes. Many factors such as technical processes, equipment, prices of power fuels and reagents, market economy, and requirements for ecological environmental protection. Generally divided into full pyrometallurgical process and full wet metallurgy process, but more is the use of joint processes, namely the combined process of pyrometallurgy and hydrometallurgy, the joint process of metallurgy and mineral processing. Therefore, rationally combine various extraction processes, take advantage of various methods, develop new smelting methods capable of handling low-grade ores and difficult-to-handle complex ores, improve and strengthen existing smelting processes, and expand resources and products. The type, high product quality, reduced production costs, and reduced environmental pollution are the tasks of extracting metallurgical workers.

The raw ore mined from the mine is often complex and has a low metal grade. Some polymetallic composite ores are often associated with a variety of valuable components and contain large amounts of gangue minerals or impurities. Except for a small amount of single ore-rich ore that can be directly smelted, most of the ore needs to be pretreated by appropriate physical or chemical methods to enrich, separate or remove harmful impurities, or to convert them into suitable smelters. With the physical or chemical state of extraction, this involves the pretreatment process of the ore material. According to the specific conditions and requirements, the most commonly used pretreatment methods for ore raw materials mainly include two processes of beneficiation and roasting.
