本文介绍了生产优质铁精矿的铁矿石及其伴生矿物的性质。据此,介绍了基于矿物性质的差异而分选铁矿物的可能性和适用选矿机械的分选特性,并讨论了可能的处理流程。文章引用了美国的试验结果,说明了高压电选法生产优质精矿的可能性和西德用巴西赤铁矿进行的试验结果,阐明浮选法生产此种精矿的可能性。
This article describes the properties of iron ore and its associated minerals that produce high quality iron concentrates. Accordingly, the possibility of sorting iron minerals on the basis of differences in mineral properties and the sorting characteristics of the beneficiation machinery are introduced, and the possible treatment processes are discussed. The article cites the results of the U.S. tests showing the possibility of producing high-quality concentrates by high-pressure electrowinning and the results of tests carried out in West Germany with hematite in Brazil, illustrating the potential of flotation for the production of such concentrates.
