银在现代技术中是一种重要的工业金属,目前其产量的15%左右用于造币,其余部分则几乎全部用于各种工业部门,成为照相、电子学、化学、医药、原子能、蓄电池、太阳能、水净化和通讯等方面必不可少的材料.因此,近20年来对银的需求不断增长,而且将继续增长.而在这期间世界原银的生产却没有显著的发展,所以生产和需求之间的不平衡与日俱增.与此同时,世界市场上银的价格持续上涨,1980年达到19美元/盎斯.银价上涨刺激了银矿的勘查和开
Silver is an important industrial metal in modern technology. At present, about 15% of its output is used for coinage, while the rest is almost entirely used in various industrial sectors and has become a major contributor to photography, electronics, chemistry, medicine, nuclear energy, batteries , Solar energy, water purification and communications, etc. As a result, the demand for silver has been growing for the past two decades and will continue to grow, while in the meantime there has been no significant growth in the production of raw silver in the world, In the meantime, the price of silver in world markets continued to rise, reaching $ 19 / oz in 1980.
