Experimental results showed that applying selective flotation process and optimum reagent condition can efficiently separate the lead-zinc minerals and obtain lead concentrate of 63.
试验结果表明:采用铅优先浮选工艺和合理的药剂条件,可以有效地实现铅锌分离,获得铅精矿品位63。
In view of the characteristics of the PbZn sulphide ore of fine dissemination size and complicated intergrowth relations,a flotation flowsheet was put forward,which consists of selective flotation of lead minerals with Na_2CO_3 and ZnSO_4 as regulators,DZ as zinc depressant,ammonium dibutyl dithiophosphate as collector,and zinc flotation using CuSO_4 as activator,butyl xanthate as collector.
针对某铅锌硫化矿嵌布粒度微细、伴生关系复杂的特点,采用碳酸钠调浆、DZ抑制锌矿物、丁铵黑药优先浮选铅,选铅尾矿用硫酸铜活化、丁基黄药作为锌矿物的捕收剂浮锌,成功实现了铅锌的有效分离,并获得了较佳的选矿指标。
The results indicated that the separation between copper and zinc was actualized through which first selecting copper by controlling zinc through rational combination of Na2S,ZnSO4 and Na2SO3,at last selecting zinc from copper tailing using preferential flotation flowsheet.
针对某复杂铜锌硫化矿石的综合回收开展分离浮选试验研究,试验研究结果表明:采用优先浮选流程,选用硫化钠、硫酸锌和亚硫酸钠合理组合抑锌选铜,最后从铜尾矿中选锌,实现了铜锌分离,获得了铜回收率73。
Some copper is preferentially floated firstly with ERAZII as capture agent, then the copper and lead co-preferential flotation is conducted, and finally the copper concentrate and lead concentrate are separated from the mixed concentrate.
采用新型铜捕收剂ERAZⅡ,部分优先浮选铜,然后铜铅混合优先浮选,混合精矿再铜铅分离。
The small and pilot scale tests of separating lead,Zinc from cyanide tail are described,Adopting preferential flotation method to recover lead, zinc from cyanide tail open vast vista in the similar mines.
