Global Aluminium Inventory to Plunge Further amid Supply Headwinds, LME Aluminium Prices to React Fast Constantly buy copper cathode production Chile, Congo and the CIS on CIF European ports. The coefficient for copper granules (Cu 98.5%) against LME copper was 96-96.25% on a cif basis, and the coefficient for bare bright copper against LME copper at 99-99.25%, on a cif basis.Ĭopper Shortage Is Irreparable Even after Biggest Mergers and Acquisitions, Here’s Why The coefficient for US brass against LME copper was 68-69%, with the fixed prices of $5,550-5,650/mt. Copper cathodes, Copper Milberry Scraps, Aluminium ingots, Petroleum Products, Sugar Icumsa 45. The supply increased slightly.įor copper scrap, cif quotes for #1 copper scrap were Comex September copper contract prices less $0.08-0.09/lb, and offers for birch/cliff were Comex September copper prices less $0.19-0.2/lb. Julia (Export Manager) Contact this Supplier. As copper prices continued to fall last week, suppliers of copper scrap were more reluctant to sell goods until Friday, when copper prices stopped falling and rebounded. The average price spread between copper cathode and copper scrap stood at 924 yuan/mt. As per the initial plans, Buenassa will produce 30,000 tons of copper cathode and about 5,000 tons of cobalt hydroxide. Prices of #1 bare bright copper without invoices averaged 59940 yuan/mt as of last Friday, down 720 yuan/mt from a week earlier. Artisanal Miner Holding Cobalt Deposit with Care. Therefore, some copper anode plate factories stopped production, and the proportion of copper scrap flowing into the smelting sector has decreased. However, because the current price difference between copper cathode and copper scrap remained below the advantage level, the profit of copper anode plate production has been squeezed. In addition, due to the relatively ample copper scrap supply, some secondary copper rod plants shifted to produce copper anode. It is worth noting that due to the huge production capacity of secondary copper rods, the supply of copper scrap in Zhejiang last week also showed a significant contraction compared with the previous week. Therefore, they will continue to release goods. Although the supply of copper scrap in various places was relatively tight, Zhejiang mainly uses imported copper scrap and most suppliers of copper scrap use hedging for risk control. Ukraine, United Arab Emirates, United Kingdom, Uruguay, USA, Uzbekistan.

Most buyers of copper scrap said that it was difficult to purchase and raw materials could not meet normal production. Looking for someone who can supply us 500MT of copper cathode on a weekly basis. Sellers were reluctant to sell their goods, and the supply of copper scrap decreased significantly compared with the previous week. Refined Copper Cathode Blocks Pure Metal Copper Cathode 99.97Min for Counter Weight, Find Details about Copper Cathode, Electrolytic Copper from Refined. Finally, the plasma parameters of the cathode spot jet predicted by the proposed numerical model are consistent with the experimental and theoretical results.Copper prices continued to fall last week, and rebounded at the end of the week.

In most of the region, the average charge state varies from 1.84 to 2.05. Beyond a certain distance from the cathode spot, the recombination and ionization rates of the ions will be insufficient to alter the ion charge state. Moreover, within 0.2 μm from the cathode spot, vaporized copper atoms quickly become completely ionized because of high electron temperature and electron density. We have recently fulfilled an order for 120000 UNIT of Electrolytic Copper Cathode (Grade A) for delivery to Australia. The expansion of the plasma jet decreases the ion density rapidly from 10 26 m −3 to 10 22 m −3, and the ions reach supersonic speed within 0.4 μm from the cathode spot. The results indicate that in the cathode spot region, there are huge electron and ion pressure gradients (10 13–10 14 Pa/m) in both axial and radial directions, resulting in the rapid expansion of the plasma jet in all directions. Simulation results are presented for different currents of the copper cathode spot (I = 3, 4, and 5 A). This work studies the physical mechanisms of supersonic ion flow in a cathode spot jet of vacuum arc by using a two-dimension magneto-hydro-dynamic numerical model that considers ionization and recombination processes. Plasma in the vacuum arc is usually generated by numerous cathode spots on the cathode surface, each of which produces a supersonic plasma jet.
