在环境污染控制问题极为重要的今天,无化学污染的强磁选技术在选别红铁矿中的应用是当前选矿技术领域重要课题之一。自1970年起,北京矿冶研究院和包钢选矿厂一起把平环永磁强磁选机应用于包头铁矿的选别中来,建成了弱磁-反浮选-强磁选流程的生产系列。继之在总结平环永磁强磁机应用于生产实践经验的基础上,又研制成功了转笼式永磁强磁选机并进行了工业试验。包头冶金研究所在1976～
In the environmental pollution control is extremely important today, non-chemical pollution of strong magnetic separation technology in the selection of red iron ore dressing is one of the important topics in the field of technology. Since 1970, the Beijing Institute of Mining and Metallurgy and the Baotou Steel Concentrator have applied the flat-ring permanent magnetic separator to the sorting of Baotou Iron Mine and built a weak magnetic-reverse flotation-strong magnetic separation process Production series. Then, on the basis of summarizing the application of flat-ring permanent magnet machine in practical production experience, we developed a new type of permanent magnet strong magnetic separator and carried out industrial tests.
