Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
(2009)A study was conducted to understand the adsorption of N-hydrocinnamoyl-N-phenylhydroxyl-amine (HCNPHA) on the surfaces of various pure minerals: sphalerite, pyrite, galena, chalcopyrite and quartz. HCNPHA is a member of ... -
Reducing the environmental impact of the flotation of sphalerite : an alternative reagent scheme
(2009)N-Hydrocinnamoyl-N-phenylhydroxylamine (HCNPHA) was found to float sphalerite without activation by copper sulphate. However, concomitant flotation of sulphidic gangue minerals, such as pyrite, significantly reduced the ...
