SMM July 10: today, the spot of electrolytic copper in North China quoted a price of 10 to 90 yuan per ton for that month's contract, with a transaction price of 50430 yuan / ton to 50730 yuan / ton. Copper prices broke through the 50, 000 mark this week to 50700 yuan / ton, rising more than 2000 yuan / ton during the week. As the maintenance of a smelter in the north has not yet been completed, although a lot of wet process copper has been increased recently, but the amount is small, and the overall consumption of wet process copper in the north is relatively small and the cycle is relatively short, the recognition of wet process copper in the north is low, and the quotation of wet process copper is as low as 100 yuan / ton, and the popularity of wet process copper is still lower than that of flat copper, so the overall supply in the north is not much, and the smelter is still willing to make a standing price, and the upper limit has been maintained at a high price of 80 yuan / ton to 90 yuan / ton. The downstream kept wait and see after the copper price soared, the bulk order transaction was less, and the long order was basically executed. Some traders took the initiative to lower the price under the fruitless quotation, and the quotation was as low as the first line of flat water, and the spot price was always in a stalemate. The quotation fluctuated in the range of 90 yuan / ton from flat water to rising water, and the average price of spot discount decreased by 50 yuan / ton compared with last week.
