Problems solved by technology

When oxidized lead-zinc ore is sulfided, 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 lead selection process is segmental flotation in which sulfide ore is selected first and oxide ore is selected, that is, lead sulfide-lead oxide, and the process is relatively long
[0006] 3) Lead oxide ore is easy to slime, and the use of conventional foaming agents is easy to carry the slime, resulting in low grade concentrate

Abstract

The invention discloses a collector for sorting lead ores, which is prepared from the following raw materials in parts by weight: 50-120 parts of pentylenepentyl alcohol, 10-30 parts of carbon disulfide, 30-80 parts of monochloroacetic acid, and n-butylamine aqueous solution 50-80 parts, pentaerythritol 50-200 parts, terpineol oil 50-150 parts, caustic soda 20-60 parts, sodium sulfide 20-100 parts, water glass solution 50-150 parts, diesel oil 10-30 parts, active nickel catalyst 0-10 parts; the volume percent concentration of n-butylamine in the n-butylamine aqueous solution is 50%-70%. In addition, the invention also provides a preparation method of the collector. The collector of the present invention has collecting performance on lead sulfide and lead oxide, therefore, the collector can select lead sulfide and lead oxide at the same time, without first selecting lead sulfide and then lead oxide. The grade and recovery rate of lead concentrate obtained by collector flotation are significantly higher than those of conventional reagents.

Description

technical field [0001] The invention belongs to the technical field of lead ore flotation, and in particular relates to a collector for sorting lead ore and a preparation method thereof. Background technique [0002] According to the degree of oxidation, lead ore can be divided into lead sulfide ore (oxidation rate is less than 10%), mixed lead ore (oxidation rate is 10% to 30%), lead oxide ore (oxidation rate is more than 30%). There are many kinds of lead oxide minerals, and the common lead oxide ore with the most industrial value is white lead ore (PbCO 3 ) and lead vanadium (PbSO 4 ). [0003] The conventional method of flotation lead oxide is to collect it with xanthate after vulcanization. The problems existing in the conventional medicament system mainly include: [0004] 1)Na 2 S dosage control and adding method. When oxidized lead-zinc ore is sulfided, it is necessary to reasonably control Na 2 If the amount of S is too large, it will cause inhibition, if it i...
