To make better use of large amounts of discarded bauxite tailings (BTs), a foamed mixture lightweight soil mixed with BTs as filler (FMLSB) was proposed. Using the orthogonal experimental design method, the effects of various contents of cement, BTs, and foam on the fluidity, wet density, unconfined compressive strength, water absorption, and ...

Leaching of zinc from calcined smithsonite using sodium hydroxide
The processes of calcination and alkaline leaching were applied to treat a zinc oxide ore, smithsonite (ZnCO3). The phase evolution in the calcination was studied, as well as the effect factors on the leaching rate of Zn, such as calcination temperature,

Mechanism of Zinc Corrosion in Accelerated Corrosion Tests
Real‐time corrosion rate of zinc was measured using electrical resistance sensors. Chloride deposition is the most corrosive phase of the test. Chloride concentration and deposition method affect corrosion throughout the test. Corrosion is accelerated by prolonged wet/dry transitions.
