In this study, d. functional theory was used to calculate the activation of Cu ions on germanium-bearing sphalerite (1 1 0) surfaces and the difference in the activation of Cu ions in sphalerite with different Ge concentrations The results show that, with an increase in Ge content, the projected d. of states on the germanium-bearing sphalerite (1 1 0) surface moves toward lower energy, and the energy gap between the Cu 3d and S 3p orbitals on the surface of the germanium-bearing sphalerite becomes larger, and the covalency and bonding strength of the Cu-S bond weaken. Through calculation and anal. of three different Cu activation models, namely Cu substitution, Cu(II) adsorption, and Cu(OH)2 adsorption, it is concluded that an increase in Ge content can hinder the Cu activation of sphalerite and can adversely affect the recovery of sphalerite and the enrichment of valuable elements in the flotation process. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Related Products of 20427-59-2).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Related Products of 20427-59-2
