contact20211230 · Bottom-blowing copper smelting technology was initiated and developed in China in the 1990s. Injection of oxygen-enriched high-pressure gas strongly stirs the molten bath consisting of matte and slag. Rapid reaction at relatively lower temperatures and good adaptability of the feed materials are the main advantages of this technology.
contactThe smelting and coal combustion was the main pollution sources that affects the HQ of heavy metals at the site, too. The determination of major pollution sources can provide a reference for pollution protection, such as optimizing mercury smelting processes thereby reducing the CR and HQ of soil in the mercury smelting site.
contact2015114 · In order to reasonably utilize the iron resources of copper slags, the smelting chlorination process was used to remove copper from copper slags. Higher holding temperature and O2 flow rate are beneficial to increasing copper removal rate. However, the Cu2O mode is formed by the reaction of surplus O2 and CuCl with O2 flow rate
