摘要: Abstract Barium slag is a kind of solid waste derived from the carbon reduction process producing barium salt. Carbon one main components in with content more than 10%. In this study, was characterized using XRF, XRD and SEM-EDS, froth flotation test introduced to recover slag. test, diesel selected as collector terpenic oil frother for separation. The influences pulp pH, dosage, dosage time were investigated. results showed that obtained concentrate had grade 63.25% its recovery 82.70% under conditions pH 8.50, 600 g/t, 500 g/t, 5 min. SEM-EDS analysis revealed coarse particle sizes homogeneous distribution. findings research provide new pathway utilization. study can be recycled raw materials, while remaining tailings utilized building material additives.
