The overall domestic copper cathode output in May was at a low level due to the intensive maintenance. Although two smelters in Shandong resumed production in May, the production of copper did not resume.
According to SMM survey, domestic 1# silver output stood at 1,200.53 mt (including 1,035.53 mt of mineral silver) in May 2022, down 3.93% on the month, mainly because many producers carried out maintenance in May.
