China’s main copper smelters increased production in April by 0.85% from the previous month, state backed research house Antaike said on Tuesday, while zinc output also rose and lead production fell from March.
Copper cathode output from the 22 companies surveyed totaled 799,500 tonnes in a month that saw virtually no smelter maintenance, Antaike said in a note; the total was up 12.85% from a coronavirus-affected April 2020.
