Abstract
Technological process is the water mixing after the dense effluent of vulcanized lead zinc flotation concentrate and the filtering of mine tailing ceramic machine；By the dense effluent of the lead concentrate containing plurality of heavy metal ion and floating agent and the dense effluent direct reuse of zinc concentrate to lead Beneficiation flowsheet and zinc Beneficiation flowsheet；Technical reform scheme：The dense effluent of lead concentrate adds lead system and selects vulcanized lead, will contain sulfuric acid zinc metal ion and the use of diethyldithiocarbamate floating agent in lead Beneficiation flowsheet (entering Turo pump pond)；The dense effluent direct reuse of zinc concentrate, sulfuric acid copper metal ion and the use of xanthate floating agent will be contained in zinc Beneficiation flowsheet, avoiding reduces the consumption of zinc sulfate and copper sulphate medicament together with zinc sulfate and copper sulphate Ar ion mixing, reduce cost for wastewater treatment.By above technological transformation, following such advantage is obtained：1st, metal loss is reduced, 2, reduce reagent consumption, save beneficiation cost, 3, improve mineral processing index, 4, reduce cost for wastewater treatment etc..
Description
Technical field：
The dense effluent sub-prime substep reuse technology of vulcanized lead zinc flotation concentrate belongs to bargh's mineral processing production technology
Field.
Background technology：
The dense effluent of vulcanized lead zinc flotation concentrate, the scheme used both at home and abroad have：Vulcanized lead zinc flotation concentrate is dense
Effluent is discharged into Tailings Dam and used, without using or being used in mixed way with tailing filtration water.Inner Mongol Zalantun City state is gloomy
Mining Limited Company lead zinc-silver polymetallic ore, main valuable component Pb 1.30%, Zn 5.25%, Ag in ore
101.50g/t, lead, zinc mainly exist with galena, zinc blend form, lead zinc ratio about 1: 4, and the grade of lead zincification is
6.5% or so ore deposit, technological process are controling differential flotation process for copper flow.Each 2000 tons one phase, second phase design of day output, specific flotation
Flow：Cyclone overflow pulp enters 2 XB-3000 surge tanks progress dosings and sized mixing, and the ore pulp after sizing mixing enters 4 XCF/
KYF-24 flotation devices enter quadrat roughing.Lead roughing operation concentrate is selected into 5 XCF/KYF-8 flotation devices 4 lead of progress, selected
After obtain lead concentrate enter it is dense, it is dense after lead ore slurry using ceramic machine filter.Lead roughing operation mine tailing enters 9 XCF/
KYF-24 flotation devices are scanned three times, are scanned rear ore pulp and are sized mixing into 2 XB-3000 surge tanks progress dosings, are sized mixing laggard
Enter 5 XCF/KYF-24 flotation devices and carry out zinc roughings, rougher concentration enter 8 XCF/KYF-8 flotation devices carry out 4 times it is selected, most
After obtain zinc concentrate enter it is dense, it is dense after zinc ore slurry using ceramic machine filter.Zinc rougher tailings enters 9 XCF/KYF-24
Scanned three times, the ore pulp after scanning enters mine tailing.
The gloomy Mining Limited Company mine of Inner Mongol Zalantun City state is poor under richness on ore body to have an opencast mining of, and lead+zinc supplies
Ore deposit grade is high, and design mineral processing circuit is the water after the dense effluent of vulcanized lead zinc flotation concentrate and the filtering of mine tailing ceramic machine
Mixing；The dense effluent of lead concentrate containing plurality of heavy metal ion and floating agent and the dense effluent of zinc concentrate is straight
Take back and use lead Beneficiation flowsheet and zinc Beneficiation flowsheet；Cause following shortcoming：1st, lead concentrate and zinc concentrate are mutually containing height.2nd, reagent consumption
Amount is big, beneficiation cost increase, 3, the mineral processing index rate of recovery it is low, 4, increase cost for wastewater treatment etc..In July, 2016 production theory
Index：Lead head grade 1.69%, argentiferous 218.22g/t；Lead concentrate grade 57.97%, argentiferous 7390.36g/t；Lead recovery
74.88%；The rate of recovery 73.94% of silver, zinc ore crude grade 10.52%, zinc concentrate grade 50.91%, rate of recovery 78.43%.
Technical reform scheme：The dense effluent of lead concentrate adds lead system and selects vulcanized lead, will contain sulfuric acid zinc metal ion and
The use of diethyldithiocarbamate floating agent is in lead Beneficiation flowsheet (entering Turo pump pond)；The dense effluent direct reuse of zinc concentrate, will contain
There are sulfuric acid copper metal ion and the use of xanthate floating agent in zinc Beneficiation flowsheet, avoid zinc sulfate and copper sulphate Ar ion mixing exists
Together, the consumption of zinc sulfate and copper sulphate medicament is reduced, reduces cost for wastewater treatment.
In March, 2017 production theory index after the completion of transformation：Lead head grade 1.29%, argentiferous 174.92g/t；Lead essence
Ore deposit grade 52.95%, argentiferous 6991.35g/t；Lead recovery 83.48%；The rate of recovery 80.75% of silver, zinc ore crude grade
10.64%, zinc concentrate grade 50.56%, rate of recovery 86.85%.
By above technological transformation, following such advantage is obtained：1st, reduce metal loss, 2, reduce reagent consumption, save ore dressing
Cost, 3, improve mineral processing index, 4, reduce cost for wastewater treatment etc..
The content of the invention：
Goal of the invention：Break through the dense effluent of vulcanization lead zinc flotation concentrate be discharged into Tailings Dam without using, use,
Or it is used in mixed way with tailing filtration water；The dense effluent of lead concentrate is added into lead system and selects vulcanized lead, sulfuric acid will be contained
Zinc metal ion and the use of diethyldithiocarbamate floating agent are in lead Beneficiation flowsheet (entering Turo pump pond)；The dense effluent of zinc concentrate is straight
Take back use, sulfuric acid copper metal ion and use of xanthate floating agent will be contained in zinc Beneficiation flowsheet, reached the raising rate of recovery with
The purpose of mineral processing production index.
Technical scheme：
The dense effluent of lead concentrate adds lead system and selects vulcanized lead, will contain sulfuric acid zinc metal ion and diethyldithiocarbamate flotation
Medicament use is in lead Beneficiation flowsheet (entering Turo pump pond)；The dense effluent direct reuse of zinc concentrate, copper sulphate gold will be contained
Belong to ion and use of xanthate floating agent in zinc Beneficiation flowsheet, avoid together with zinc sulfate and copper sulphate Ar ion mixing, reduction
The consumption of zinc sulfate and copper sulphate medicament, reduce cost for wastewater treatment；Reach and reduce metal loss, reduce reagent consumption, section
Beneficiation cost is saved, mineral processing index is improved, reduces the purpose of cost for wastewater treatment.
