Conclusions
We reported the removal process of Pb and Sb in the copper smelting business.
Both metals have been made as products with a quality that have been acceptable
in the market. HMC is an indispensable process in copper smelting, and to develop
the recycling business further, it is important to remove impurities efficiently, whilst
maintaining safety and the environment. HMC stabilizes the copper smelting business
by removing impurities.
