前言我国锡矿资源得天独厚,分布地区较广,类型齐全。然而,我国的锡产量从1967年开始处于比较严重萎缩状态,1975年以来锡产量大幅度下降,从过去的世界第二位降至目前的第六位,出口量锐减,国内供应几乎到了不能自给的程度。如果此种趋势发展下去,我国将面临从传统锡出口国变为锡进口国这一严重局面。有关文章预测,我国和世界上许多国家都将面临锡矿资源消耗量越来越大,锡产品不断下降,供不应求的局面,加之一些大量的潜在锡矿资源一时还得不到利用,
Preface Our country tin resources are unique, the distribution area is wider, the type is complete. However, China’s tin production has been in a severe decline since 1967. Since 1975, the tin production dropped drastically from the second place in the world to the sixth place at present. The export volume dropped drastically, and the domestic supply almost can not. The degree of self-sufficiency. If this trend continues, China will face the serious situation of changing from a traditional tin exporter to a tin importer. The article predicts that China and many countries in the world will face an increasing consumption of tin resources, tin products continue to decline, the supply situation, coupled with a large number of potential tin resources temporarily unavailable,
