Research progress of ilmenite flotation
摘要
Abstract
The key problems of ilmenite flotation technology and the review of its research progress were discussed to promote the efficient utilization of resources.By combing the characteristics of ilmenite resources,the mechanism of commonly used collectors,inhibitors and activators were analyzed,and the application effects of magnetic separation pretreatment,flocculation flotation,"magnetic separation-flotation"combined process,as well as the performance advantages of GF+JJF flotation machine,cyclone-static microbubble flotation column and other equipment were summarized.The results show that the composite collector(such as NaOL/SPA)and the combined process can increase the recovery rate of ilmenite to more than 80%.The new flotation column can increase the concentrate grade to 48.21%and maintain the recovery rate of 81.17%.In the future,the development of ilmenite should focus on the development of environmentally friendly reagents,the application of intelligent equipment and the optimization of fine particle recovery technology,so as to realize the green and efficient separation of ilmenite.关键词
