Problems solved by technology

When sulfiding zinc oxide ore, it is necessary to reasonably control Na 2 If the amount of S is too large, it will cause inhibition, if it is too small, it will not achieve the effect of vulcanization; adding Na 2 S generally needs to be added in sections, resulting in a longer process
[0005] 2) The conventional process is more complicated
The existing zinc selection process is segmental flotation in which sulfide ore is selected first and oxide ore is selected, that is, zinc sulfide-zinc oxide, and the process is relatively long

Abstract

The invention discloses a collecting agent for sorting zinc oxide ore. The collecting agent is mainly prepared by the following raw materials in parts by weight: 50 to 100 parts of isobutanol, 50 to 120 parts of sodium hydroxide, 60 to 120 parts of carbon disulfide, 10 to 200 parts of 1-amino-n-heptane, 50 to 100 parts of glycerol, 50 to 120 parts of salicylhydroxamic acid, 10 to 30 parts of sodium carbonate, 20 to 100 parts of sodium sulfide, 50 to 150 parts of water glass solution and 10 to 40 parts of kerosene. In addition, the invention also discloses a preparation method of the collecting agent. The collecting agent has collecting performance for both zinc sulfide and zinc oxide, the zinc sulfide and the zinc oxide can be simultaneously sorted, the process of sorting the zinc oxide after the zinc sulfide is sorted is not needed, the collecting agent is high in selectivity, the ore sorting process is simple in flow, the cost is low, the grade of the zinc concentrate obtained in a floatation manner is greater than 35%, and the grade and the recovery rate are obviously higher than those of conventional chemicals.

Description

technical field [0001] The invention belongs to the technical field of flotation of zinc oxide ore, and in particular relates to a collector for sorting zinc oxide ore and a preparation method thereof. Background technique [0002] Zinc-containing ores can be divided into zinc sulfide ores (oxidation rate less than 10%), mixed zinc ores (oxidation rate 10% to 30%), and zinc oxide ores (oxidation rate above 30%) according to the degree of oxidation. There are many kinds of zinc oxide minerals, and the most common zinc oxide ore with industrial value is smithsonite (ZnCO 3 ) and hemimorphite (Zn 4 [Si 2 o 7 ](OH) 2 h 2 O). [0003] At present, the main method of recovering zinc oxide ore is to collect it with primary amine collectors after sulfidation. The main problems in the conventional pharmaceutical system are: [0004] 1)Na 2 S dosage control and adding method. When sulfiding zinc oxide ore, it is necessary to reasonably control Na 2 If the amount of S is too ...
