removal of arsenic minerals in sulfide flotation

Mineral flotation in the presence of hydrogen peroxide A high degree of oxidation of the copper and arsenic surface species occurred when the minerals were conditioned in oxygen and with H 2 O 2 As an example Tables 2 and 3 shows the trends in surface oxidation for tennantite as the oxidising condition was changed from nitrogen to oxygen and to hydrogen peroxide
