人口、资源、发展将成为21世纪的三大主题。社会迅速发展对矿物资源的需要与日俱增,而人均资源消耗量将是衡量一个国家经济发展水平的重大标志之一。 资源危机及技术的兴衰资源危机 矿产资源作为国民经济的一个重要组成部分面临着新世纪带来的严峻挑战。全球矿产资源日趋贫、细、杂,而传统的选矿理论及工艺已难适应资源的变化及国民经济发展的需要。冲破传统选矿观念的束缚,大

Population, resources and development will be the three major themes of the 21st century. The rapid development of society requires ever-increasing mineral resources, and the per capita consumption of resources will be one of the major indicators of a country’s economic development.
