ANTAIKE: China's output of lead and zinc in July rose more slowly than expected from the prior month due to restrictions on power use in key production hubs, state-backed research house Antaike said on Tuesday.

Refined zinc and zinc alloy production from 51 smelters surveyed was 461,000 tonnes last month; that was up 9,700 tonnes from June and up 7.1% year-on-year, although average daily output fell 1.1% on the month.
