Embodiment 1

[0028] A grading jig sorting zircon beneficiation process, comprising the following steps:

[0029] (1) Use a high-frequency vibrating sieve to classify the raw materials into minerals of three particle sizes of +0.2mm, -0.2+0.074mm and -0.074mm;

[0030] (2) Minerals with grain size of -0.2+0.074mm are subjected to jigging treatment (stroke is 90mm, punching frequency is 150 times / min) to obtain concentrate 1 and tailings 1, and minerals with grain size of -0.074mm are obtained through jigging treatment concentrate 2 and tailings 2;

[0031] (3) Tailings 1 is combined with minerals of +0.2mm size, and processed by jigging (120mm stroke, 200 strokes / minute) to obtain concentrate 3 and tailings 3;

[0032] (4) Concentrate 1, concentrate 2 and concentrate 3 are combined into zircon jigging concentrate, and tailings 2 and tailings 3 are combined into tailings 4 .

Embodiment 2

[0034] A grading jig sorting zircon beneficiation process, comprising the following steps:

[0035] (1) Use a high-frequency vibrating sieve to classify the raw materials into minerals of three particle sizes of +0.2mm, -0.2+0.074mm and -0.074mm;

[0036] (2) Minerals with grain size of -0.2+0.074mm are subjected to jigging treatment (60 strokes, 130 strokes / min) to obtain concentrate 1 and tailings 1, and minerals with grain size of -0.074mm are obtained through jigging treatment concentrate 2 and tailings 2;

[0037] (3) The tailings 1 is combined with the minerals of +0.2mm size, and after jigging (90mm stroke, 150 strokes / min), concentrate 3 and tailings 3 are obtained;

[0038] (4) Concentrate 1, concentrate 2 and concentrate 3 are combined into zircon jigging concentrate, and tailings 2 and tailings 3 are combined into tailings 4 .

Embodiment 3

[0040] The difference between this example and embodiment 1 is:

[0041] The tailings 4 of Example 1 were made into slurry with a mass concentration of 50%, and flotation reagents were added to perform flotation for at least 20 minutes to obtain a flotation concentrate, and all the concentrates were combined. The dosage of flotation reagents is: dextrin 100g / t pulp, sodium humate 200g / t pulp, caustic soda 50g / t pulp, sodium oleate 60g / t pulp, nitrilotriacetic acid sodium 100g / t pulp, copper chloride 50g / t pulp, rhamnolipid 12g / t pulp, carboxymethyl cellulose sodium 4g / t pulp.

Abstract

The invention provides an ore dressing process for sorting zirconite by a classification jigger. The ore dressing process comprises the following steps of (1) classifying raw materials into minerals with three size fractions of +0.2 mm, -0.2+0.074 mm and -0.074 mm; (2) performing jigging treatment on the minerals with the size fraction of -0.2+0.074 mm to obtain concentrates 1 and tailings 1, andperforming jigging treatment on the minerals with the size fraction of -0.074 mm to obtain concentrates 2 and tailings 2; (3) combining the tailings 1 with the minerals with the size fraction of +0.2mm, and performing jigging treatment to obtain concentrates 3 and tailings 3; and (4) combining the concentrates 1, the concentrates 2 and the concentrates 3 into zirconite jigging concentrates, and combining the tailings 2 and the tailings 3 into tailings 4. According to the ore dressing process, a zirconite ore sample is divided into three levels of +0.2 mm, -0.2+0.074 mm and -0.074 mm for jigging and reselection, the grade of the zirconite after graded jigging is improved to 48%, and the recovery rate reaches 86%.

Description

technical field [0001] The invention relates to the technical field of ore dressing, in particular to a zircon ore beneficiation process for classifying and jig-separating. Background technique [0002] Zirconium-titanium ore is a non-metallic ore that is in short supply in my country. At present, it is mainly imported from abroad. Among them, Australia is the most important importing country, and Yimeizhi Minerals is also the largest imported ore. Its main ore is zircon, and it also contains monazite, quartz, kyanite, sillimanite, garnet, tourmaline, etc. other ores. [0003] At present, the separation methods of zirconium and titanium used in the industry are mainly magnetic separation and shaking table. The beneficiation effect is poor, the average recovery rate is only about 50%, and the grade is not high, so it is difficult to achieve the purpose of comprehensive recovery. Contents of the invention [0004] In view of the deficiencies in the prior art, the present i...
