The practicability of a pyrometallurgical scheme for raw material processing is established as result the analysis methods intended to dearsenate and process gold-arsenic concentrates well equipment execution. conceptual design vacuum without forced movement dispersed in sublimator reaction zone materials proposed. In-process tests sublimation arsenic sulfides from gravity flotation received Ba...

This project builds on our previous published work using the stable isotope dilution method to estimate the bioavailability of soil Pb in human volunteers who ingest milligram quantities of soil (and microgram quantities of Pb) in gelatin capsules. The primary aims of this project are to: 1) determine estimates of the bioavailability of Pb in soils from a mining site, smelting site and urban si...
