摘要:
主要综述了全球锌资源及其开发利用情况.锌是一种重要的有色金属,主要应用于镀锌和锌合金,主要的矿床类型有海底喷气沉积矿床(Sedex)、密西西比河谷(MVT)型等,全球锌矿资源分布相对集中,澳大利亚、中国、秘鲁三国保有全球锌资源储量的58.18%,2016年度三个国家的锌产量占全球产量的55.88%.全球锌资源开发以地下开采为主,矿石类型多为硫化矿,采用浮选工艺富集锌,2014年度锌矿石平均入选品位为5.5%.

Abstract:
In this article , the distribution and utilization of global zinc resource were summarized . Zinc, which was one of the most important nonferrous metals , mainly used in galvanized industry and zinc alloy preparation industry .The main zinc deposit types were Sedex , MVT etc.The distri-bution of zinc resource was relatively close , the reserves of zinc resources in Australia , China and Peru account for 58 .18%of the world's zinc reserves , and the three country produced 55 .88%of the global zinc production in 2016 .In global zinc resources exploitation field , underground mining was the main mining method , sulphide ore was the main ore type and flotation was the main benefi-ciation technology .According to the statistics in 2014 the average feed grade of zinc ores was 5.5%.
