Application Research on the Recovery of Barite from Lead-zinc Tailings

With the aim to recover barite from the lead-zinc tailings in Qinghai,the two kinds of technological flowsheets of gravity separation and flotation-gravity separation were carried out according to its properties.Finally,the combined technology of flotation-gravity separation was adopted,obtaining a barite concentrate of 90.18% BaSO4 with a recovery of 52.45%,which effectively recovered barite in the tailings and brought remarkable economic benefits for the enterprise.
