Applied Orthogonal Experiment Design for the Optimum Extraction Conditions of High Concentration Selenium from Maifanite
Abstract: In order to improve the concentration of selenium in the maifanite concentrate, the optimum experimental conditions were obtained by orthogonal experimentas follows: size of maifanite was 10 mesh, concentration of maifanite was 15 (expressed as the quality of maifanite divided by that of water), soaking time was 60 min at room temperature, heating temperature was 70oC, heating time was 20 min, pH value was 6. Under this condition, the concentrations of each element (ppm)determined by ICP-AES were: Fe 0.099, Cu 0.035, Mn 0.051, Zn 0.019, Se 0.028, Al 0.000.a ven in this document.
