1. Pyrometallurgical copper smelting: Pyrometallurgical copper smelting is the main method to produce copper at present, and more than 80% of the copper in the world is extracted from copper sulfide concentrate by pyrometallurgy. The most prominent advantages of pyrometallurgical copper smelting are strong adaptability, low energy consumption and high production efficiency.

2. Wet copper smelting: Wet copper smelting is a method of extracting copper from solution. Copper can be extracted from poor ore or rich ore, oxidized ore or sulfide ore by hydrometallurgy. The advantages of copper hydrometallurgy are simple equipment and easy operation. Copper can be extracted at room temperature without using blast and smelting equipment, saving fuel. Copper can be produced in this way as long as there is bile water.

Copper is a transition element with atomic number 29 and chemical symbol Cu. Pure copper is a kind of soft metal. When it is just cut, its surface is reddish-orange with metallic luster, and its simple substance is purplish red.

Copper has good ductility, high thermal conductivity and electrical conductivity, so it is the most commonly used material in cables, electrical and electronic components, and can also be used as building materials to form a variety of alloys.
