Reducing the environmental impact of the flotation of sphalerite : an alternative reagent scheme
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 ...
Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
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 ...
