Variography of ores from the Rubtsovsk massive-sulfide copper-lead-zinc deposit (Altai Territory)
      
Isotopic ratios of trace amounts of lead in pyrite and pyrrhotite have been successfully used to distinguish unmineralized Ordovician from mineralized Silurian black shales around the Woodlawn copper-lead-zinc prospect.
      
Al Amar Fault is a "copper-lead line" dividing a Pb-Ag subprovince (of sialic derivation?) from a Cu-Zn-Au sub-province (of plate margin/island arc derivation?).
      
Thermal analysis and kinetics of the copper-lead matte roasting process
      
In this paper, the results of copper-lead matte investigations are presented.
      
Investigated copper-lead matte is intermediate product of the lead production in TREPCA-Zve?an.
      
In the second part of the paper kinetic parameters describing oxidative roasting of copper-lead matte are presented.
      
The influence of alloy composition on microstructure and tensile behaviour of copper-lead alloys
      
The tensile fracture behaviour of cast copper-lead alloys
      
Conditions of preparation of copper-lead alloy powder
      
Powder mixtures of three systems, viz., aluminum-graphite, copper-lead, and aluminum-lead are studied.
      
Hypermonotectic copper-lead alloys were directionally solidified at unit gravity on earth and also in the cyclic gravitational environment attainable during flight of NASA's KC-135 aircraft.
      
A thermodynamic analysis of the copper-lead-sulfur system at 1473 K
      
A thermodynamic analysis of the copper-lead-sulfur system at 1473 K
      
The diffusivity of oxygen in liquid copper-lead alloys
      
The oxygen diffusivity in liquid copper-lead alloys at 1403 K (1130° C) was measured using the electrochemical cell: Ni-NiO/ZrO2(+CaO)/O in liquid Cu-Pb alloy(I)/ZrO2(+CaO)/O in liquid Cu-Pb alloy (II).
      
The diffusivity of oxygen in liquid copper-lead alloys
      
The oxygen diffusivity in liquid copper-lead alloys at 1403 K (1130?C) was measured us-ing the electrochemical cell: Ni-NiOJZrO2(+CaO)/O in liquid Cu-Pb alloy(I)/ZrO2(+CaO)/O in liquid Cu-Pb alloy(II).
      
It was found that the oxygen diffusivity in liquid copper-lead alloys did not change dras-tically over the entire composition range, in contrast with that reported by other investi-gators for liquid copper-nickel alloys.
      
Thermodynamic properties of liquid copper-lead alloys
