The extraction of palladium(Ⅱ) from acidic media with cyclic sulfoxide derivative-α-octyl-tetrahydrothiophene-l-oxide (OTMSO) was investigated. The extraction
The epitaxial techniques are the most important processes in the production of semiconductor materials and optoelectronic devices. Liquid phase epitaxy (LPE) an
Rutile separation from calcite, apatite and quartz by flotation was investigated. The results show that the rutile separation from calcium and silicon gangue mi
