equipment for recovering copper from furnace slags. Pyrometallurgical production of copper generates two slags smelting furnace slag and converter slag which contain cu and cu, respectively the following three methods are generally utilized for recovering the copper from these slags on an industrial scale i recycling of the converter slag to the smelting furnace,
Smelter slags are a waste product from the pyrometallurgical processing, typically stored in piles or stocks around or near the smelter site. Research on slags has focused on potential environmental issues related to the weathering of slag dumps or on its utility as a construction material as road ballast, road base or sub-base material, or reprocessing for secondary metal recovery.
Jan 23, 2017 The cakes are broken up with hammers, the eye-bolts are withdrawn, and the slag goes through the crusher, and is loaded on railroad cars, ready for use as ballast.

Sep 15, 2003 In northern Arizona where the volcanic ash has a redish color, the BNSF uses red lava rock. A former SP line running alongside the San Pedro River toward the Mexican border uses only copper smelter slag, since there was a large smelter in Douglas, Arizona when that line was built and they probably didnt even have to pay for it.
