平桂矿区砂锡矿的开采已有上百年的历史,大量较富的易于开采回收的资源目前几乎开采殆尽。随着资源的减少,平桂锡生产的水平也年复一年的大幅度下降,直至近年来出现了严重生产亏损的局面。这种危机的产生,从表面上看似乎主要是资源问题,但认真分析起来并非如此。资源确是在逐渐减少,但当前并未达到枯竭的地步,而主要原因是过去的自我封锁造成的。在世界贸易高度发展的今天,每种资源都具有国际意义。所以资源的价值应主要取决于生产成本与产品的国际市场价格。由于国内市场锡的价格远低于国际市场价格,造成了平桂大量砂锡矿资源不应有的积压。随着这种封锁的逐步打破,认真的不失时机的着手考虑平桂砂锡矿资源的开发利用,已提到议事日程上 The mining of sand and tin ore in Pinggui Mining Area has been going on for more than a hundred years. A large number of relatively abundant resources that are easy to mine and recover have been almost depleted at present. With the reduction of resources, the level of production of Pinggui tin also dropped significantly year after year until in recent years there has been a serious production loss situation. The emergence of such a crisis appears to be mainly resource problems on the surface, but it is not so seriously analyzed. The resources are indeed declining, but the current state of exhaustion has not yet reached the level of depletion, mainly due to past self-denial. Today, with the highly developed world trade, every resource has international significance. Therefore, the value of resources should mainly depend on the cost of production and the international market price of the product. As the domestic market price of tin is far lower than the international market prices, resulting in Pinggu a large number of sand and tin resources should not have the backlog. With the gradual break-up of this blockade and serious consideration of the opportunity to consider the development and utilization of the Pinggu sandstone tin resources, it has been mentioned on the agenda
