自从1927年大阪精炼厂开始生产硒以来,其产量随着铜阳极泥处理量的增加而增加,目前的生产能力约18吨/月。该厂处理阳极泥的特点是用一台短回转窑进行氧化焙烧,以亚硒酸钠溶液形式回收硒。
Since the beginning of production of selenium at the Osaka refinery in 1927, its output has increased with an increase in copper anode mud capacity, with a current capacity of about 18 tons / month. The plant is characterized by the anode mud oxidation calcination using a short rotary kiln to recover selenium in the form of sodium selenite solution.
