SMM July 24th: today, the spot of electrolytic copper in North China quoted a price of 40 to 100 yuan per ton for that month's contract, with a transaction price of 51340 yuan / ton to 52040 yuan / ton. Recently, the supply of goods in the smelter is not abundant, the quotation is firm, and the upper limit has always been maintained at 100 yuan per ton, but it is difficult to make an actual deal. Traders said that the purchase desire in the lower reaches was mediocre, the copper price went up and down during the week, and the terminal order was poor. The performance of long order delivery was not positive, and the overall consumption could hardly be improved, and we could only rely on the part brought about by low prices that needed to be replenished, so traders offered prices voluntarily. So that the spot price to maintain a wide range of water 20 to 100 yuan / ton, the overall performance of both supply and demand is weak, spot water quotation stalemate pattern.
