Interfacial Adsorption Mechanism of Diethyldithiocarbamate in High-Sulfur Residue Flotation

Diethyldithiocarbamate (DDTC) is employed in the sulfide ore flotation process due to its excellent collection performance. Herein, we investigated interfacial adsorption behavior of DDTC on four main mineral phases high-sulfur residue: sulfur, pyrite, sphalerite, and lead sulfate. The H2O, namely, structure energy electron localization function cross section, were explored using density theory calculation. results helpful constructing a coadsorption model which was validated by pure characterization Fourier transform infrared spectra. indicated that sulfate weak with physical bonding, while pyrite strong chemical bonding. Practical bench-scale residue performed, result different from obtained flotation. Our developed predictions fugacity pattern analysis synergistically used explain this difference. Overall, work proposes for first time H2O provides important insights into
