多年来,国内各铁选厂测铁方法一直延用化学分析方法。这种方法虽具有一定的优越性,但由于操作程序复杂,分析速度较慢,从样品取出到报出结果约需一个小时以上,远远不能满足指导选矿生产的需要。为此我们经过反复试验于1982年12月,将X射线荧光分析仪用在铁矿浮选产品分析上,取得了良好效果。1983年6月开始,由鞍钢矿山公司批准在东鞍山选厂推广应用。实践表明,应用效果良好。
Over the years, all domestic iron processing plant iron measurement methods have been using chemical analysis methods. Although this method has some advantages, due to the complexity of the operation procedure and the slow analysis speed, it took about an hour to remove the sample from the report to report the result, which is far from meeting the need of guiding the beneficiation production. To this end, we have repeatedly tested in December 1982, the X-ray fluorescence analyzer used in iron ore flotation product analysis, and achieved good results. Beginning in June 1983, Anshan Iron and Steel Company approved the application of plant selection in the East Anshan. Practice shows that the application of good results.
