Inhibited mechanism of carboxymethyl cellulose as a galena depressant in chalcopyrite and galena separation flotation

Minerals Engineering, 2020
Carboxymethyl cellulose (CMC) is a highly efficient, nontoxic, and biodegradable depressant in Cu-Pb separation. However, poor understanding of the interaction mechanism has hindered the application of CMC in this separation process.

Selective depressive effect of pectin on sphalerite flotation and its mechanisms of adsorption onto galena and sphalerite surfaces

, 2021
In this work, pectin was investigated as a non-toxic and eco-friendly sphalerite depressant in the flotation separation of galena and sphalerite. The selective adsorption of pectin on sphalerite surfaces was predicted by molecular dynamics simulations ...

Galvanic interaction between different grinding media and galena (1 0 0) surface and its influence on galena flotation behavior: A DFT study

Applications of Surface Science, 2022
Galena has different electrostatic potentials from grinding medium. Collision and friction occur between them in the grinding process, which lead to electron transfer and charge redistribution on galena surface, affecting surface oxidation and galena ...

Metal remobilization from country rocks into the Jiaodong-type orogenic gold systems, Eastern China: New constraints from scheelite and galena isotope results at the Xiadian and Majiayao gold deposits

Ore Geology Reviews, 2021
Orogenic gold deposits in the Jiaodong Peninsula contain more than 5000 t of known gold resources. Precambrian metamorphic rocks and Mesozoic granite represent the main host rocks for these deposits, but gold deposition (∼120 Ma) is significantly younger
