on the mechanism of the order of mineral deposits can considerably promote better understanding of the genesis of lead and zinc sulfide ore deposits. Two factors, internal and external, control whether... precipitation in the lead-zinc deposits in this area, which substantially affects our understanding of the temporal-spatial distribution law of ore-forming elements and deposit types to direct mineral......
某砂岩型低品位氧化铅锌矿选矿工艺谭欣1,2,何发钰2,吴卫国2,魏明安2,孙传尧2(1.北京市北京科技大学土木与环境工程学院2.北京市北京矿冶研究总院 矿物加工科学与技术国家重点实验室)摘 要:研究云南某砂岩型低品位复杂难处理氧化铅锌矿的选矿富集新工艺.确定的工艺流程为"预先分级磨矿-混合浮选硫化铅和黄铁矿然后分离-混合浮选尾矿浮选硫化锌-硫化锌浮选尾矿磁选回收褐铁矿-磁选尾矿依次浮选氧化铅和氧化锌".通过有效的组合调整剂和复合捕收剂实现了氧化铅锌矿物的不脱泥浮选回收.选矿富集的氧化锌精矿(磁选精矿+浮选精矿)......
获各琦铜矿铅锌矿石的选矿特性王顺青1(1.内蒙古自治区巴彦淖尔市临河区内蒙古巴彦淖尔西部铜业有限公司)摘 要:西部铜业公司获各琦铜矿铅锌矿石含有机碳,矿物之间嵌布复杂,铅锌可浮性差,磁黄铁矿含量高,可浮性变化范围大,分离回收难度大,通过大量的试验研究与工业调试,选择了比较合理的工艺流程和药剂制度,实现了铅锌浮选分离,获得了较好的选别指标.关键词:选矿工程； 铅锌矿； 可浮选性......

氧化铅锌矿直接硫酸浸出贺山明1,王吉坤2,李勇1(1.云南省昆明市昆明理工大学冶金与能源工程学院2.云南冶金集团股份有限公司 技术中心,昆明 650031)摘 要:探讨用硫酸直接浸出氧化铅锌矿,研究各种因素对浸出的影响.结果表明,在最佳工艺条件下,锌的浸出率可达97%以上,铅入渣率可达98%以上,产液速率大于162.5 L/m2·h,渣含锌约2.5%,渣含铅量高达40%以上,浸出渣可送往炼铅系统处理.关键词:冶金技术； 氧化铅锌矿； 硫酸浸出； 过滤性能； 浸出率； 铅入渣率......
inclusion geochemistry were discussed for understanding the source of the ore-forming metal, fluids and the mineralization processes in Fankou-type lead-zinc deposit. The strata, fault structure and REE results show that this type deposit experiences pyrite and lead-zinc mineralization processes, the former gets closer provenance contact with limestone, while ore metal of the latter does not come......
ore was the molar ratio of NaOH to molar sum of zinc oxide, silica and lead oxide in zinc oxide ore. 3 Results and discussions 3.1 Characterization of zinc oxide ore XRD pattern and SEM image of zinc... was also synthesized.

in the southwestern side of the Dayaoshan lead-zinc mupltimetal zone in China. The REE, S isotope, Pb isotope and fluid influsion geochemistry were discussed for understanding the source of the ore metal and the characters of ore-fluids in Panlong lead-zinc deposit. The results show that the low ΣREE and enriched LREE of the ore and wall rock pronounce the positive Eu anomaly and weak negative Ce anomaly......
. The following treatment strategy was applied to a sample of this ore: gold flotation–gold concentrate leaching–lead and zinc flotation from the gold concentrate leaching residue. Closed-circuit trials of gold flotation yielded a gold concentrate that assayed at 40.23 g·t-1 Au with a recovery of 86.25%. The gold concentrate leaching rate was 98.76%. Two variants of lead-zinc flotation from the residue......
