AN EXPERIMENTAL STUDY ON THE ACTIVATION AND TRANSPORTATION OF LEAD AND ZINC IN CLASTIC STRATUM OF COUNTRY ROCKS IN JINDING LEAD-ZINC DEPOSIT, YUNNAN PROVINCE
The determination of mineral inclusions for their temperature,sulfur and lead isotopes at different ore-forming stages inthe Fankou lead and zinc deposit shows that the temperatures are 300±50℃ at the first stage and 250±50℃ at the second andthird stages.
Electric-field-induced phase transition in single-crystal lead zinc niobate
The behavior of lead zinc niobate, a relaxor ferroelectric, in electric fields has been studied by dielectric, optical transmittance, and small-angle light scattering techniques.
Research on natural plants in the lead/zinc mine in northwestern Guizhou Province
The complex antimony-lead/zinc deposit at Rujevac/Yugoslavia; its specific geochemical and mineralogical features
Since 1973, about 500,000 tons/yr of metal-rich particulate tailings from a lead/zinc flotation mill have been discharged through a submarine outfall into a two fjord system on the west coast of Greenland.
Test Determination of Lead and Zinc in Water with the Use of Xylenol Orange Immobilized on Silica
The results obtained in determining ions of lead and zinc in the case of their simultaneous presence in solution and comparative characteristics of various calibration models are presented.
Geology and structural features of vein-type lead and zinc deposits
Part of lead and zinc in fluids can be transported by organic complexes, while their precipitation is caused by organic reduction.
