A micro-fine particle antimony oxide ore recycling method includes the following steps: first utilizing sodium carbonate as a dispersing agent to disperse micro-fine particle antimony oxide ore in a stirring bucket, then grading the micro-fine particle antimony oxide ore, reselecting the graded micro-fine particle antimony oxide ore through a micro-fine particle table respectively to recycle micro-fine particle antimony oxide rough concentrate of different particle grades, finally combining and concentrating the micro-fine particle antimony oxide rough concentrate of different particle grades, then conducting floatation to recycle micro-fine particle antimony oxide to obtain antimony oxide concentrate. By means of the method, the micro-fine particle antimony oxide ore can be effectively recycled. Under the condition that the feeding antimony grade is 0.67%-1.36%, the micro-fine particle antimony oxide concentrate with the antimony grade being 27.56-29.67% and the recovery rate being 76.11-79.50% can be acquired.

First with sodium carbonate, making dispersant disperses in agitator microfine Antimony Oxide Ores, then by the classification of microfine Antimony Oxide Ores, adopt microfine shaking table to carry out respectively gravity treatment microfine Antimony Oxide Ores after classification and reclaim to obtain the microfine antimony oxide rough concentrate of size fractionated, after finally again the microfine antimony oxide rough concentrate of size fractionated being merged, concentrated, carry out again flotation and reclaim microfine antimony oxide, comprise the following steps and regime of agent:
(1) adopt sodium carbonate to make microfine Antimony Oxide Ores dispersant,
(2) during classification positive and negative 10 microns as a grade scope,
(3) while adopting table concentration, 8～12 millimeters of shaking table strokes, 270～330 beats/min of jig frequencies,
(4) in floatation process, microfine antimony oxide rough concentrate after merging is added after flotation cell, add again NaOH, CMC and starch combination to suppress gangue mineral, finally add again lauryl amine to make the collecting agent of microfine Antimony Oxide Ores, through one roughing, scan triple cleaning for three times and obtain microfine antimony oxide concentrate
(5) the total consumption of medicament is:
During use, described medicament is first mixed with to following concentration expressed in percentage by weight:
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Outstanding advantages of the present invention is:
1, the Antimony Oxide Ores more low-grade, granularity is fine effectively can be reclaimed, obtain higher antimony oxide concentrate grade and the rate of recovery.
2, flowage structure is simple, and dosing is few.
