摘　　要：这是一篇矿物加工工程领域的文章。河北某铅锌矿中主要有价元素为铅、锌,品位分别为1.07%、2.08%。矿石中的铅主要赋存于方铅矿中,另有白铅矿、硫酸铅、铅铁矾等含铅矿物,锌主要赋存于硫化物闪锌矿中,占总锌的66.96%,其次为氧化锌矿物,锌氧化率较高。在实验研究中,确定了在-0.074 mm 65%的磨矿细度条件下,优先浮铅再浮锌的工艺。浮选产品中,铅精矿产率1.74%,铅精矿中铅、锌、铜品位分别为51.73%、10.86%、3.81%,回收率分别为83.93%、8.98%、68.20%;锌精矿产率为2.26%,锌精矿中铅、锌、铜品位分别为1.25%、51.64%、0.73%,回收率分别为2.63%、55.42%、16.97%。This is an article in the field of mineral processing engineering.The main valuable elements in a lead-zinc mine in Hebei are lead and zinc,with grades of 1.07%and 2.08%,respectively.Lead in the ore mainly occurs in sulfide galena,and lead-containing minerals such as galena,lead sulfate and lead jarosite.Zinc mainly occurs in sulfide sphalerite,accounting for 66.96%of the total zinc,followed by zinc oxide minerals,with high zinc oxidation rate.In the experimental study,the process of preferential flotation of lead and then zinc at the condition of grinding fineness of-200 mesh content of 65%was determined.The yield of lead concentrate is 1.74%,the grades of lead,zinc and copper in lead concentrate are 51.73%,10.86%and 3.81%,respectively,and the recoveries are 83.93%,8.98%and 68.20%,respectively.The yield of zinc concentrate is 2.26%,the grades of lead,zinc and copper in zinc concentrate are 1.25%,51.64%and 0.73%,respectively,and the recoveries are 2.63%,55.42%and 16.97%,respectively.
