Anonymous users2024-02-08Metallurgy is the process and process of extracting metals or metal compounds from ores and using various processing methods to make metals into metal materials with certain properties. Metallurgical technology mainly includes pyrometallurgy, hydrometallurgy and electrometallurgy, and metallurgy has a long history of development in China, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development is integrated with the development of metallurgy.
With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science, so there is a metallurgical engineering major in universities. ]

Anonymous users2024-02-02Metallurgy is the process of extracting metal compounds from minerals by some means of processing. Metallurgical technology is mainly divided into electrometallurgy, hydrometallurgy and pyrometallurgy. Metallurgy was originally developed from copper smelting in pottery.
The metallurgical industry is mainly divided into ferrous metallurgy industry, non-ferrous metallurgy industry, rare metal metallurgy industry, and powder metallurgy industry. The ferrous metallurgy industry refers to the production of copper, iron, etc. Non-ferrous metallurgical industry refers to the processing and production of various metals.
In the smelting technology, pyrometallurgy is mainly a metallurgical process carried out under high temperature conditions. Including, drying, roasting, roasting, smelting, refining, distillation, etc.
Hydrometallurgy is mainly a metallurgical process carried out in solution. Including, leaching, purification, preparation of metals, etc. Electrometallurgy is mainly a method of extracting metals using electrical energy.
It is further divided into electrothermal metallurgy and electrometallurgy. Metallurgy is essentially the process of removing impurities to obtain pure compounds.
Metallurgical Overview:
Metallurgy, developed from ancient pottery. The first is copper smelting. The melting point of copper is relatively low, and with the development of pottery, the working temperature required for pottery is getting higher and higher to reach the melting point temperature of copper.
In the process of making pottery, pottery was made in some places where there were copper mines, and copper was naturally found to be attached to biomass. With the accumulation of experience, the ancients gradually mastered the smelting method of copper.

Although the formal definition of corporate social responsibility (CSR) has been discussed many times in domestic and foreign forums, there is still no consensus. At present, the CSR concept is generally recognized internationally: while creating profits and being responsible for the interests of shareholders, enterprises should also assume social responsibilities to employees, society and the environment, including compliance with business ethics, production safety, occupational health, protection of the legitimate rights and interests of workers, and resource conservation. >>>More

Sketches in a broad sense are very broad, and sketches in a narrow sense generally refer to the shorter art of speaking and acting, and its basic requirements are clear language, natural form, and the ability to fully understand and show the character characteristics and language characteristics of each character, the most representative is comedy sketches. The history of sketches has a long history, and China's comedy sketches originated in the early 80s, which inherited and developed the advantages of dramas, cross talk, two-person turns, small dramas and other repertoire. Especially famous for Zhao Benshan, Chen Peisi, Zhu Shimao, Song Dandan, Huang Hong, Cai Ming, Guo Da, and Pan Changjiang, among them, only Zhao Benshan has inherited the authenticity of local language arts, and at the same time, he also has the potential to be a talk show superstar. >>>More
