(一)处理低品位铅锌混合精矿的可能性(赞比亚的试验)罗得西亚矿含有硫化锌、硫化铅、硅酸锌、硅酸铅、炭酸锌和炭酸铅等多种矿物。浮选产出的锌精矿采用湿法冶炼,铅精矿用 Mewman 法进行冶炼。其他矿物再以重介质选矿方法得低品位铅锌混合精矿,采用铅锌鼓风炉提炼铅和锌。英国帝国熔炼公司对罗得西亚矿进行试验时所用的物料种类很多,如尾矿、铅精矿、混合细尾矿、炼铅炉老渣和水冶浸出渣等。用白云石作熔剂,以碎焦作为补加燃料配入烧
(A) Possibility of handling low grade lead-zinc concentrate (Zambian test) The Rhodesian mine contains various minerals such as zinc sulfide, lead sulfide, zinc silicate, lead silicate, zinc carbonate and lead carbonate. Zinc concentrate flotation using wet smelting, lead concentrate by Mewman method smelting. Other minerals and then heavy medium beneficiation methods have low-grade lead-zinc concentrate, the use of lead-zinc blast furnace to extract lead and zinc. British Empire Smelting Company of Rhodes West mine used when testing a wide range of materials, such as tailings, lead concentrate, mixed fine tailings, lead smelting furnace slag and water leaching residue. Use dolomite as a flux and use crushed coke as additional fuel to burn
