Formation conditions of Au-Mo(W)-Pb-Zn ores of the Bugdain atypical porphyry deposit, Eastern Transbaikalia, Russia
      
Compositions of magmatic melts and evolution of mineral-forming fluids in the banska Stiavnica epithermal Au-Ag-Pb-Zn deposit, S
      
Melt and fluid inclusions were investigated in minerals from igneous rocks and ore (Au-Ag-Pb-Zn) veins of the Stiavnica ore field in Central Slovakia.
      
The mineralogy and PT formation conditions of the Dzhimidon Pb-Zn deposit in the Sadon ore district are considered.
      
This opens up opportunities for discovering economic Au-Ag and Pb-Zn ores in the ore field.
      
The geological and structural position and localization conditions of the vein-type Pb-Zn deposits of the Sadon (North Ossetia) and East Karamazar (North Tajikistan) ore districts are considered.
      
The study of fractures and faults at Pb-Zn deposits is important for understanding of the formation conditions of other hydrothermal deposits.
      
Organic fluid involved in Pb-Zn mineralization in the polymetallic deposit of Qixiashan probably derives from bacteria and algae, and is similar to that of the mature crude oil system.
      
We investigated the composition of the vegetation in two former mining regions in Central Slovakia: Banská ?tiavnica with predominant Pb-Zn contamination and Staré Hory with a very high Cu content in the soil.
      
Species such as Agrostis capillaris, Acetosella vulgaris, Arabidopsis arenosa, and Thlaspi caerulescens appear frequently on Pb-Zn mine wastes.
      
Several differences in the vegetation structure were detected between the Pb-Zn and Cu mine heaps; higher amounts of vascular plants and fewer lichen species covered the Pb-Zn mine heaps.
      
This paper discusses the application of the model in predicting for hydrothermal Cu, Ag, Au and Pb-Zn occurrences in northwestern Yunnan.
      
One potential superlarge Pb-Zn ore occurrence with himalayan thermal brine genesis-Wuqia Region, Xinjiang, China
      
The paper focuses on geological and geochemical evidence of thermal brine genesis of Pb-Zn deposits in Wuqia district, Xinjiang.
      
Ore-forming conditions of superlarge Pb-Zn deposits studies show that there exists tectonic and sources setting of Jinding-type superlarge Pb-Zn deposits in this area.
      
Mineral deposit model was described and prospecting potentiality of superlarge Pb-Zn deposit and their significance were discussed.
      
The optimum conditions for the original potential flotation of galena from Pb-Zn-Fe sulfide ores are as follows: pH values of 12.5-12.8, potential of 150-180 mV and with diethyldithioncarbamate (DDTC) as collector.
      
Life cycle inventory analysis of CO2 and SO2 emission of imperial smelting process for Pb-Zn smelter
      
A multi-objective intelligent coordinating optimization strategy based on qualitative and quantitative synthetic model for Pb-Zn sintering blending process was proposed to obtain optimal mixture ratio.
      
In all the duck brains examined, Spearman correlation coefficients were significant and positive for Zn-Mn, Cu-Mn, Cu-Fe, and Pb-Fe; a negative correlation was found for Pb-Zn.
