一、绪言随着世界范围内深刻的经济衰退,1982年为矿业在历史上受到冲击最为严重的一年,而钼工业尤甚。从1973年到1980年的产销统计(表1)表明,这期间对钼的需求是坚挺的。因而,各生产公司加快了他们的勘探,矿山评价和矿山开发。1980年,产量创纪录,还有更多的生产能力在建设中。虽然在1981年下半年,主要生产公司开始削减产量,但产量仍高,库存大增。1982年的特点是,库存不断增高,产量大量缩减,价格显著降低。 I. INTRODUCTION With the profound economic recession in the world, mining industry was hit hardest in history in 1982, while the molybdenum industry was even worse. The production and sales statistics from 1973 to 1980 (Table 1) show that the demand for molybdenum is strong during this period. As a result, production companies accelerated their exploration, mine evaluation and mine development. In 1980, production was record and there was more capacity under construction. Although in the second half of 1981 the major production companies began to cut their output, their output was still high and their inventories soared. The year 1982 was characterized by an ever-increasing inventory, a drastic reduction in output and a significant reduction in prices.
