Problems solved by technology

The old tailings of cassiterite polymetallic sulfide ore are characterized by low grade and many valuable elements. The valuable elements available for recovery include tin, zinc indium, antimony lead, sulfur, and arsenic, and most of them are conjoined organisms. Part of it is fine-grained, and the degree of oxidation of sulfide ore is deepened. Traditional technology is used to sort old tailings, and its sorting index is poor.

Embodiment 1

[0020] Embodiment 1: Treatment of a cassiterite polymetallic sulfide ore tailing in Guangxi containing 0.56% tin, 0.89% lead, 0.78% antimony and 1.54% zinc. use as figure 1 Shown technological process, concrete technological parameter is:

[0021] ①Tail throwing: Use spiral concentrator equipment in parallel to recover materials from -2mm to +0.074mm from tailings with a concentration of 27%. Second sweep.

[0022] ②Pb-antimony-zinc mixed flotation: the dosage of butylamine black is 100 g / ton of raw ore, and the dosage of phenyl halide quaternary ammonium salt is 150 g / ton of raw ore; a process of roughing once and sweeping twice is adopted.

[0023] ③Lead antimony flotation: the dosage of ethylsulfurium helium is 100g / ton of raw ore, the dosage of zinc sulfate is 600g / ton of raw ore, the dosage of lime is 2500g / ton of raw ore, and the dosage of calcium humate is 500g / ton of raw ore. A process of rough selection, two scans, and four selections is adopted.

[0024] ④Zinc fl...

Abstract

The multi-metal cassiterite sulfurizing tail concentrating method includes: graded tail throwing with combineed screw concentrating machine and screw chute; floating of the rest tail with phenyl halogenated quaternary ammonium salt and black butyl amine as collecting agent to recover sulfurized mineral of Pb, Sb, Zn, etc and sulfurized mineral oxide of Pb, Sb, Zn, etc while leaving the cassiterite and gangue inside the trough; and recovering cassiterite with sodium carbonate and carboxymethyl polyvinyl alcohol as combined gangue dispersing and inhibiting agent and through stepped floating process. Compared with traditional method, the method has concentrating grade raised by 1-3 times, comprehensive tail loss of about 10 % and 10 % raised recovering rate of Pb, Sb, Zn, Sn, etc.

Description

technical field [0001] The invention relates to a beneficiation method for cassiterite polymetallic sulfide ore tailings. Background technique [0002] Mineral resources are an important non-renewable natural resource. A large amount of tailings will be discharged during the beneficiation process. Especially with the improvement of the utilization of mineral resources, the mineable grade of ore will decrease accordingly, resulting in a sharp increase in the amount of tailings. Tailings are both mine waste and potential secondary resources. Effective development of them is an important part of the comprehensive utilization of mineral resources and an important way to save and utilize mineral resources. The old tailings of cassiterite polymetallic sulfide ore are characterized by low grade and many valuable elements. The valuable elements available for recovery include tin, zinc indium, antimony lead, sulfur, and arsenic, and most of them are conjoined organisms. Part of it i...
