Every year from June to August marks the conventional maintenance season for primary lead smelters. Most enterprises will halt equipment operations by mid-June, with production expected to significantly decrease in late June. After the maintenance, anode slime raw material inventory will gradually decrease, and precious metal production will enter the maintenance phase by month-end June. Therefore, silver production at some manufacturers may slightly decline in June, but the decline in silver production at lead smelters will mainly occur in July.
