我国铅锌矿资源丰富,探明储量居世界前列.目前铅锌产量还不能满足国内建设的需要,但就资源条件和工业基础而言,铅锌工业具有一定的潜力.一、我国铅锌矿地质经济评价的几点特征探明储量大.富矿约占总储量的三分之一以上.全国主要矿山平均开采品位与世界主要铅锌生产国相近.我国的矿石以锌为主,探明储量中铅锌比为0.43:1.00,而世界平均为1:1.国际市场锌精矿的价格是铅精
China’s lead-zinc resources are abundant, and proven reserves rank among the top in the world. At present, lead and zinc production can not meet the needs of domestic construction. However, in terms of resource conditions and industrial basis, lead-zinc industry has certain potential. First, China’s lead-zinc mine The characteristics of geological economic evaluation have many proven reserves. The high-grade ore accounts for about one-third of the total reserves. The average mining grade of major mines in the country is similar to that of the world’s major lead-zinc producers. China’s ore is dominated by zinc and proved reserves. The lead-zinc ratio is 0.43:1.00, while the world average is 1:1. The price of zinc concentrate in the international market is lead concentrate.
