Zinc extraction from oxide ore has been paid more and more attention to due to the exhaustion of zinc sulfide ore resources. In this work, the volatilization kinetics of Zn from the flotation products of low-grade lead–zinc oxide ore during carbothermal reduction in the temperature range of 900–1300 °C were investigated. The phase transformation …

Corundum growth can thus be assumed to have taken place in the presence of aqueous fluid. In the following, we assume that an interconnected fluid phase was present throughout the lithologies, which allowed for element exchange between ultramafic, granite and aluminous lithologies, and led to development of the corundum …
