Determination of sub-microgram amounts of bismuth

A method is described for the flotation and determination of sub-microgram levels of bismuth in water. Bismuth(III) in a 1000ml sample of water is coprecipitated with iron(III) hydroxide at pH 4.0±0.2. The precipitate is floated with the aid of a mixed surfactant (sodium dodecyl sulphate and sodium oleate) and small air bubbles, then separated ...

Hydrogen peroxide (H2O2) is a strong oxidizer that causes non-selective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not well-documented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a Mo-Bi-containing ore was intensively investigated by batch flotation tests. Results showed that the addition of H2O2 significantly ...
