2021-2-8 The emission of SO2 during cement production will lead to environmental pollution, but cement clinker has a certain effect on sulfur fixation. To study the mechanism of sulfur fixation of cement clinker, we have separated the sulfur-containing minerals in cement clinkers by the three-step method of reverse-phase extraction, separation and enrichment. In addition, we have analyzed the mineral ...

The effects of leaching temperature and time on the extraction efficiencies of Ni2+ and Co2+ were investigated in detail under microwave conditions. It is shown that the extraction efficiencies of Ni2+ and Co2+ from the ...
