There are many types of electrolytic copper melting furnaces (also known as cathode furnaces), including reverberatory furnaces and shaft furnaces using heavy oil as fuel, electric arc furnaces and induction furnaces.
The picture shows the schematic diagram of the structure of the copper melting reverberatory furnace, and the table shows the refractory materials for the reverberatory furnace and shaft furnace.
According to foreign media reports, the spot price of sulfuric acid has soared due to tight supply, and Chile's electrolytic copper production has suffered as a result. Codelco's Gabriela Mistral copper production fell by 40% in the first quarter of 2021. The reason for the shortage of sulfuric acid was that the slowing down of oil refining during the epidemic led to a shortage of sulfur. At the same time, Asian industries gradually recovered. The sulfuric acid produced was basically consumed locally, and the supply of exports to Chile was limited. Although some smelters in Chile produce sulfuric acid as a by-product, the widely used solvent extraction-electrodeposition technology requires a large amount of sulfuric acid. Under the background of sulfuric acid shortage and labor negotiation risks and epidemic factors, it is difficult for Chile to maintain a high level of copper production. In addition, Cochilco said that if the sulfuric acid shortage situation worsens, it may affect 12% of Chile's copper production.
The economic data released overnight by the United States was generally better than expected, the US$3.5 trillion tax and expenditure plan was suspended, and the US Strategic Petroleum Reserve deal would release 1.5 million barrels of crude oil. The heavy rains hit New York City, the United States entered a state of emergency, and Powell won a House of Representatives. With the support of important members of the Democratic Party, the Bank for International Settlements and the four countries carried out central bank digital currency experiments. Xi Jinping: deepened the reform of the New Third Board, established the Beijing Stock Exchange, and Dalian Commodity Exchange raised the margin level for speculative trading of coking coal and coke futures contracts.
As of August 16, China’s electrolytic copper stocks were 159,500 tons, which was at a relatively low level in the same period in history. In the off-season cycle, low inventories provided a certain bottom support for copper prices. Copper prices fluctuated around 70,000 yuan/ton. . Judging from the current supply and demand links, there is room for copper inventory to rebound, but the upward trend of inventory is relatively moderate, which limits the subsequent rise in copper prices.
On the morning of December 5, 2017, the project of Huludao Hongyue North Copper Electrolytic Copper Plant was fully completed. Sun Yi, Secretary of the Huludao Municipal Party Committee, and Yu Hong, Chairman of Huludao Hongyue Group, cut the ribbon for the opening of the electrolytic copper plant in the operation room.
On May 22, 2018, the representative of the Russian owner visited Jiangxi Tianxin for an inspection.
