In this article, Baowu will show you what is copper ingot.
Copper ingots are electrolytic purification of copper: blister copper (containing 99% copper) is pre-made into thick plates as anode, pure copper is made into thin sheets as cathode, and a mixture of sulfuric acid and copper sulfate is used as electrolyte. After electrification, copper dissolves from the anode into copper ions and moves to the cathode. After reaching the cathode, electrons are obtained and pure copper is precipitated at the cathode. The copper plates produced in this way, called "electrolytic copper", are of extremely high quality and can be used to make electrical products.
Copper extraction methods are divided into pyrometallurgy and hydrometallurgy. The development of copper metallurgy technology has gone through a long process, but so far copper smelting is still dominated by pyrometallurgy, and its output accounts for about 85% of the world's total copper output. The technology of modern hydrometallurgy is gradually being promoted. The launch made the smelting cost of copper much lower.
Copper ingots are also divided into red copper ingots and brass ingots.
Red copper ingot is a kind of copper ingot, which has strong compression resistance and corrosion resistance. Physicochemical properties of copper ingots: purple-red luster metal. Slightly hard, extremely tough and wear-resistant. There is also good ductility. Good thermal and electrical conductivity. Copper and some of its alloys have good corrosion resistance and are stable in dry air. Soluble in nitric acid and hot concentrated sulfuric acid, slightly soluble in hydrochloric acid. Easily attacked by alkali. Main use: widely used in electrical, light industry, machinery manufacturing, construction industry and other fields.
Brass ingot refers to a block made of brass. The main component is copper and silver not less than 96%, up to 99.3%, and the main impurity elements are zinc, arsenic, antimony, bismuth, and lead. Mainly used for refining.
The above is the definition and use of copper ingots and other small knowledge, if you want to know more knowledge, please feel free to pay attention to Baowu.
