铅和锌是国家经济建设和国防建设所不可缺少的重要有色金属。我国铅锌生产虽已有相当的增长,但仍不能适应“四化”建设发展的需要。我国铅锌资源是十分丰富的,铅的储量仅次于美国,居世界第二位,锌则比加拿大还多,居第一位。但是,我国现有铅锌冶炼量,(按设备能力计),也不到铅锌储量的1％,而在世界上其它国家平均为3～3.5％,发达国家就更高。可见,我国铅锌资源的开发程度甚低,发展我国铅锌工业的潜力是很大的。为了充分发挥我国资源的这一优势,
Lead and zinc are important non-ferrous metals indispensable to national economic and national defense construction. Although the production of lead and zinc in our country has been fairly increased, it still can not meet the needs of the “four modernizations” construction and development. China’s lead and zinc resources are very rich, lead reserves second only to the United States, ranking second in the world, zinc is more than Canada, ranking first. However, the existing lead-zinc smelting capacity in China (less than 1% of the total lead-zinc reserves) is less than 1% of the total lead and zinc reserves, while the average for other countries in the world is 3% to 3.5%, which is much higher in developed countries. It can be seen that the development level of lead and zinc resources in our country is very low and the potential for developing lead and zinc industries in our country is great. In order to give full play to this advantage of our country’s resources,
