Minerals Yearbook, 1989: Mining and Quarrying Trends in the Metals and Industrial Minerals Industries

摘要

The domestic mining industry continued to be strengthened and revitalized in 1989. The healthy conditions and the industry comeback that began in 1987 continued to spread and became more established for many commodities. Relatively comfortable and stable commodity prices, still found predominantly in the metals sector, reinforced other operational factors in bringing vitality to the mining and mineral processing industries. New streamlined business practices, mine and plant modernizations, and the progressive use of new technologies successfully helped lower operating costs and increase efficiency during the past 5 to 7 years. Major topics discussed in the report include mining highlights, legislation and government actions, exploration, development, underground mining, surface mining, remote mining, beneficiation, health and safety.
