浮选机在国外,1980年浮选的主要技术进展表现在大型浮选机在工业上的应用。浮选贫矿石只有规模大的选矿厂才能见到经济效益。1980年会有2.5—10万吨级大型浮选厂建成,一些国家(如智利、美国和苏联等)正在考虑设计日处理10万吨级铜浮选厂,从而迫使浮选机大型化以满足工业要求。Wemco浮选机最大容积为28.3米~3,菲律宾Dizon浮选厂规模为17000(吨/日),粗选作业只用28台。菲律宾Sa-lsino1980年安装容积为28.3米~3的Agiatar浮选机28台。Denver又称DR浮选机,最大型号为DR1275或DRCO1275容积为36米~3,
Flotation machine abroad, in 1980 the main technological progress in the flotation flotation machine in large industrial applications. Flotation lean ore only large-scale concentrator to see the economic benefits. In 1980 there will be 2.5-10 million tons of large-scale flotation plant built, some countries (such as Chile, the United States and the Soviet Union, etc.) is considering the design day processing 100,000 tons of copper flotation plant, which forced the flotation machine to meet the large Industrial requirements. Wemco flotation machine maximum capacity of 28.3 meters to 3, the Philippines Dizon flotation plant size of 17,000 (tons / day), roughing operations only 28 units. Sa-lsino, Philippines, in 1980, 28 sets of Agiatar flotation machine 28 28.3 m. Denver, also known as DR flotation machine, the largest model for the DR1275 or DRCO1275 volume of 36 m ~ 3,
