its an ore that we take out with a very high concentration of zinc and lead. the zinc have an average of 41% and lead of 20% on a composite sample and we have approx 3000000tons of it 1 ton bulk bags and we can start on 130 metric tons per month and escalate after that.

Chemical Specification (Component) for the custom in (Zn) 99,995% (Pb) 0,6% (Cd) 0,02% (Fe) 0,08% (Cu) 0,07% Zinc is specified as below: Aluminum doped zinc oxide (AZO) films are prepared by rf magnetron sputtering on glass or Si substrates using specifically designed ZnO targets containing different amount of Al2O3 powder as the Al doping source. The structural, electrical, and optical properties of the AZO films are investigated in terms of the preparation conditions, such as the Al2O3 content in the target, rf power, substrate temperature and working pressure. The crystal structure of the AZO films is hexagonal quartzite. The orientation, regardless of the Al content, is along the c axis perpendicular to the substrate. The doping concentration in the film is 1.9 at.?% for 1 wt?% Al2O3 target, 4.0 at.?% for 3 wt?% Al2O3 target, and 6.2 at.?% for 5 wt?% Al2O3 target. The resistivity of the AZO film prepared with the 3 wt?% Al2O3target is ~ 4.7Ã?10-4 O?cm, and depends mainly on the carrier concentration. The optical transmittance of a 1500-Ã?-thick film at 550 nm is ~ 90%. The optical band gap depends on the Al doping level and on the microstructure of the films, and is in the range of 3.46?3.54 eV. The optical band gap widening is proportional to the one-third power of the carrier concentration.
