金和银作为重要的商品,在投资、工业与艺术品方面,一直保持着它们的传统作用。相对于生产成本来说,目前金和银的价格有利于大小规模的贵金属生产的持续发展。新开发矿山的金银产量仍满足不了需要。联合金矿有限公司(Consolidatd Gold Fields Ltd.)1979年的资料表明,世界金的总供给量为1765吨(5700万盎司),1979年世界各方面金的用量占总用量的百分数为:珠宝约占42％、工业占10％、投资占25％、货币和纪念章占18％(合计95％)。1977年银产量为38900万盎司,而世界银的消耗量为41100万盎司,其中约1/3的银用于照相业,其余用于艺术品、电子工业、货币及其它
Gold and silver, as important commodities, have always maintained their traditional role in investment, industry and art. Relative to the cost of production, the current gold and silver prices are conducive to the sustainable development of large and small precious metals production. Newly-developed mine of gold and silver production still can not meet the needs. According to 1979 data from Consolidatd Gold Fields Ltd., the total supply of gold in the world was 1,765 tons (57 million ounces). The percentages of gold used in various fields in the world in 1979 were as follows: 42%, industry 10%, investment 25%, currency and medal 18% (total 95%). Silver production was 389 million ounces in 1977 compared with 411 million ounces consumed by the World Bank, of which about one-third of silver was for photography and the rest for art, electronics, currency and others
