  • Near Zero Waste Processing Of Low Grade Complex Primary

    sep 01, 2020 among the listed low-grade primary ores and the secondary industrial residues, zinc is one of the elements whose recovery appears worthwhile. the use of zinc-containing waste sources is restricted due to zinc purity requirements set by the manufacturers and, consequently the recycled to virgin material ratio is critical and only small ratios lead and zinc smelting. 333. secondary lead processing. the secondary production of lead begins with the recovery of old scrap from worn-out, damaged, or obsolete products and with new scrap. the chief source of old scrap is lead-acid batteries; other sources include cable coverings, pipe, sheet, and other lead-bearing metals. solder, a tin-basedoct 26, 2010 the global zinc industry is currently experiencing unprecedented interest in new developments and expansions. while most of the new projects and plant upgrades remain committed to traditional processing technologies, recent advances in zinc solvent extraction have created opportunities for new process routes in the treatment of both primary ore and secondary materials.
