Statistical investigation of flotation parameters for copper recovery from sulfide flotation tailings

This study is focused on the froth flotation reprocessing of a copper mineral from tailings. The effects parameters including pulp density, collector dosage, frother and dispersant dosage were statistically examined to obtain an effective approach for concentrating minerals. sample ore used in this was mainly wastes that have been stored more than 30 years comprised mixed sulfide minerals partially oxidized sulfides. We conducted 24 factorial design main influence performance. results showed optimum condition at dosages 80 ​g/t, 150 ​g/t collector, frother, respectively with recovery grade 60% 8% respectively. From analysis experimental results, we concluded though various performance, its interactions other paramenters are most influential factors.
