Abstract

Abstract: The development status and industrial application of selective flocculation-flotation process，selective flocculation-magnetic separation process，and flocculation desliming process for the ultrafine iron minerals are summarized.Progress on research of the main factors for flocculation of ultrafine iron minerals including dispersant，flocculant，calcium and magnesium ions，flow-field characteristics are introduced.Finally，the development direction in flocculation technique of ultra-fine iron minerals is proposed in strengthening the investigation on the selective process of dispersion and flocculation，flow-field characteristics of in flocculation process，and high efficient flocculation process and equipment.

Key words: Ultra-fine iron mineral, Flocculation separation, Research status, Development direction
