A smelter exposed to zinc fumes reported severe recurrent episodes of cough, dyspnea and fever. Bronchoalveolar lavage showed a marked increase in lymphocytes count with predominance of CD8 T-lymphocytes. Presence of zinc in alveolar macrophages was assessed by analytic transmission electron microscopy. This is the first case of recurrent bronchoalveolitis related to zinc exposure in which the ...

All aluminium smelter plants discharges high volume extremely toxic electrolytic cell waste known as spent pot liner. Over the years scientists have improvised various methods for disposing these toxic wastes either by diluting with inert material or recovering its carbon value after decontaminating the toxic waste. Present paper outlines conceptual design of a commercial treatment plant which ...

Activities performed at mineral processing operations are capable of producing significant quantities dust. To ensure that regulatory compliance is maintained throughout operation, dust levels monitored by routine analysis air filter samples. Determining the quantity and type particulate matter present in allows for operation to identify sources where warranted, implement a suppressant strategy...

Current U.S. policies aim to establish domestic supply chains of critical minerals for the energy transition. The Iron Creek deposit in Idaho cobalt belt (ICB) is one most promising (Co) targets. Our case study illustrates importance mineralogy strategic evaluations mineral potential. Most Co at occurs as Fe substitution pyrite, with lattice-bound and inclusion-hosted Ag, As, Bi, Ni, Pb, Se, Te...
