The oxidation ratio of some lead zinc ore is 92%. Using sulphurization xanthate to float lead, sulphurization amine to float zinc, no desliming technology, and D 6 modifier can obtain this result: lead concentrate contains lead 60 80%, zinc 5 84%, and lead recovery rate is 92 72%, zinc concentrate contains zinc 36 4%, lead 0 5%, and zinc recovery rate is 83 22%.
A mineral processing technology for Tangjia lead zinc ore which adopted a lead zinc sulfur selective flotation scheme and sodium aulfite as depressant for pyrite was proposed. The technology has the advantage over partial bulk flotation scheme including selective flotation of zinc after lead sulfur bulk flotaiton,and the minerial processing index can be increased greatly by using the technology.
From dacite-porphyries→Cu-Pb-Zn ore→Pb-Zn ore,the content of K~(+),Na~(+),Ca~(2+),Mg~(2+),Cl~(-),F~(-) in liquid phase of fluid inclusion is going to decline while SO~(2-)_4content is increasing,indicating more oxidability in fluid.
It is perfectly feasible in technology that for the low-grade Pb-Zn ore containing carbon and pyrite which has higher floatability, a selective flotation of lead can be performed without using cyanide. It, furthermore, is also of benefit to economy.
The total amour of REE is relativety low and the anomaly parameters of Eu and Ce are weak-depleted through detailed research on REE geochemistry of various types of ore-bearing siliceous rocks and lead-zinc ores in Xicheng ore field.
A series of experiments of annealing crystal growth of the lead-zinc ores from the Fankou lead-zinc deposits have been made in the devices of high-temperature microscope, micro-heating stove and video tape recorder.
Mineralogy and PT formation conditions of lead-zinc ore at the Dzhimidon deposit, north Ossetia
In this study the authors studied acute effects of 5 toxic metals (cadmium, mercury, lead, chromium and arsenic) and a lead-zinc ore on microsomal mixed function oxidase system of the male rat.
Study on the multi-sources of ore-forming materials and ore-forming fluids in the Huize lead-zinc ore deposit
Pyrometasomatic lead-zinc ore deposits of the Kamioka mine occur in the Hida metamorphic complex of central Japan.
Re-examination of organic matter from the lead-zinc ore bodies has shown that abundant microfossils characteristic of lacustrine environments are present, and substantiates earlier results of Love and Zimmerman (1961).
One potential superlarge Pb-Zn ore occurrence with himalayan thermal brine genesis-Wuqia Region, Xinjiang, China
Trace elements in galena and sphalerite and their geochemical significance in distinguishing the genetic types of Pb-Zn ore depo
Lead isotope behaviour in a polyphased Pb-Zn ore deposit: Les Malines (Cévennes, France)
Les Malines Mine (Cévennes, France) provides an example of Pb-Zn ore bodies that underwent a polyphased evolution.
Most of the Cévennes Pb-Zn ore bodies could derive from this Triassic metal stock; nevertheless, local Pb isotopic anomalies suggest hydrothermal sources for some Pb-Zn ore bodies located along the Cévennes fault.
