Significance of scrap copper recycling in Tianjin

Tianjin copper scrap recyclingThe meaning of

Copper scrap has a great recovery function, and the regeneration process is very simple。First, the collected copper scrap is sorted。Copper scrap without pollution or copper alloy with the same composition can be used directly after melting in the furnace;Copper scrap with serious pollution should be further refined to remove impurities.For mixed copper alloy scrap, the composition needs to be adjusted after melting。

Copper scrap has a great recovery function, and the regeneration process is very simple。First, the collected copper scrap is sorted。Copper scrap without pollution or copper alloy with the same composition can be used directly after melting in the furnace;Copper scrap with serious pollution should be further refined to remove impurities.For mixed copper alloy scrap, the composition needs to be adjusted after melting。Slj1208zd through such regeneration treatment, the physical and chemical properties of copper are not damaged, and the recycling of copper waste makes it completely updated。Recycled copper scrap should be treated in two steps。The first step is to dry and burn off organic matter, such as engine oil and grease。The second step is to smelt the metal and remove the metal impurities in the slag。

Misunderstanding 1: Some people think that copper is a metal that is in short supply for a long time in China, and there is no surplus problem。The construction of copper smelting capacity can also make full use of foreign mineral resources, so copper smelting projects should not be restricted。I think this view is one-sided。There are many kinds of copper scrap, and the recycling technology and process are different, but they are generally divided into pretreatment and recycling。The so-called pretreatment is to mix the copper waste, classify it, select other waste with mechanical inclusions, remove the oil on the surface of the copper waste, and finally obtain a single and relatively pure copper waste, which provides excellent raw materials for smelting, thus simplifying the smelting process。There are many ways to recycle copper scrap, which can be divided into two categories: direct use and indirect use of copper scrap。Direct utilization is the direct smelting of high-quality copper scrap into fine copper or copper alloy, indirect utilization is the removal of copper scrap through smelting base metal, cast into anode plate, and then through electrolysis to obtain electrolytic copper。
