Embodiment 1

[0025] Embodiment one: An ultrasonic separation and smelting process for treating zinc leaching slag

[0026] From figure 1 and 2 It can be seen that the present invention is an ultrasonic separation and smelting process for treating zinc leaching slag. The pre-ultrasonic leaching system 52 is composed of the ore mill 2, the pulping machine 18, the ultrasonic leaching machine 19, the filter 6, the pulping machine 21, the ultrasonic washing machine 22, and the filter 8; the post-ultrasonic flotation system 53 , consisting of pulping machine 23, ultrasonic vulcanizing machine 35, pulping machine 34, ultrasonic dispersing machine 33, inflatable flotation machine 31, ultrasonic dispersing machine 39, inflatable flotation machine 37, pulping machine 46, ultrasonic dispersing machine 47, inflatable Flotation machine 49, filter 44 are made up of. Its technical principle and working process are:

[0027] Zinc leaching slag 1 and hot water 13 are dosed according to a solid-to-liq...

Embodiment 2

[0050] Embodiment two: An ultrasonic separation and smelting process for treating copper-containing zinc leaching slag

[0051] From figure 2 It can be seen that the present invention is an ultrasonic separation and smelting process for treating copper-containing zinc leaching slag, and its engineering design is basically the same as that of Embodiment 1, the difference being that the medicament added in a roughing pre-slurry process In 26, add thiocarbamate (50-200g / t); add thiocarbamate (50-100g / t); Sodium thioglycolate (20-100g / t) is added to the chemical agent 41 added in the slurry mixing process; the first-time selection tailings slurry 50 is copper concentrate, and the copper concentrate is subjected to open-circuit treatment.

[0052] Apply the ultrasonic separation and smelting method of this embodiment to process the zinc leaching residue 1 containing 0.8% copper, obtain ultrasonic washing filter residue 17 containing 2.4% copper in the pre-ultrasonic leaching sy...

Embodiment 3

[0054] Embodiment three: An Ultrasonic Separation and Smelting Process for Treating Silver-Free Zinc Leach Slag

[0055] From figure 2 It can be seen that the present invention is a kind of ultrasonic separation and smelting process that does not contain silver-zinc leaching slag, and its engineering design is basically the same as that of Embodiment 1. The difference is that it does not need to add Y89 and (or ) pentaxanthate. Zinc-lead-silver symbiotic or semi-growth lead-zinc ores are very common in lead-zinc sulfide ore resources, but in the lead-zinc sulfide ores in western Hunan, almost no silver minerals are contained. Among lead-zinc oxide ores, there are also many lead-zinc resources that do not contain silver or contain very little silver. Applying this embodiment to treat silver-free zinc leaching slag is beneficial to saving the cost of chemicals.

[0056] It can be seen from the above examples that the present invention relates to a medicament formulation fo...

Abstract

The invention relates to a reagent formula used for a zinc leaching residue floatation process and an application method of the reagent formula. The reagent is a floatation reagent which is added into floatation processes such as sulfurizing, rough floatation, scavenging and concentration. The reagent formula is characterized in that 1) one or two of sodium sulphide and sodium hydrosulfide are added into a sulfurizing process as a sulfurizing reagent; 2) in the rough floatation process, N,N-sodium diethyldithiocarbamate, butyl ammonium black powder and 25# black powder are added as lead mineral collecting agents, Y89 and (or) pentyl xanthate are added as silver mineral collecting agent(s); 3) in a scavenging process, one or two of sodium sulphide and sodium hydrosulfide are added as the sulfutizing agent(s), N,N-sodium diethyldithiocarbamate, butyl ammonium black powder and 25# black powder are added as the lead mineral collecting agents, and the Y89 and (or) pentyl xanthate are added as the silver mineral collecting agent(s); and 4) carboxymethylcellulose is added as a gangue inhibiting agent in a concentration process. After applying the reagent formula disclosed by the invention, by adopting one-time rougher floatation, one-time scavenging and one-time concentration, lead yield can reach up to more than 95% and lead tail run can reach 0.1-0.2%.

Description

Technical field [0001] The invention relates to a formulation and usage of flotation agents, in particular to a formulation and usage of agents used in the flotation process of zinc leaching slag, and belongs to the technical field of wet separation and smelting. Background technique [0002] Zinc leaching slag is the leaching slag produced during the leaching process of zinc in wet smelting. Due to the difficulty of handling zinc-lead-silver symbiosis and the limited technical means of previous treatment methods, the zinc leaching slag contains about 15-22% zinc and about 5-5% lead. 8%, containing about 30-300g / t silver. The main phases of zinc in zinc leaching slag are zinc ferrite and zinc sulfate, the main phases of zinc leaching slag are lead alum and lead silicate, and the main phases of silver in zinc leaching slag are silver sulfide and elemental silver. According to the "Method for Recovering Zinc from Leach Slag Containing Zinc Ferrite" (ZL96118245.8) invented by ...
