一、前言司家营铁矿是我国大型铁矿床,矿体北区赋存有九千多万吨贫赤铁矿。其中有用矿物主要有磁铁矿、假象赤铁矿、半假象赤铁矿。矿物呈细粒不均匀嵌布,属难选贫赤铁矿。为了确定合理的工艺流程,多年来不少科研单位进行了广泛的研究工作,其中弱磁——强磁——正浮选半工业试验取得了良好的效果。经鉴定可做为设计依据。为了弄清烷基磺酸钠浮选司家营假象磁铁 I. Foreword The Si Jiaying Iron Ore is a large-scale iron ore deposit in China. There are over 90 million tons of poor hematite in the northern part of the ore body. The main useful minerals are magnetite, artifact hematite, and semi-artificial hematite. Mineral particles were uneven cloth, is difficult to pick lean hematite. In order to determine a reasonable process, many scientific research units over the years conducted a wide range of research work, of which weak magnetic - magnetic - are flotation semi-industrial test achieved good results. Identified as a design basis. In order to understand the sodium alkyl sulfonate flotation division camp imaginary magnet
