Embodiment Construction
[0027] An oxygen-sulfur mixed ore treatment process, the treatment process comprises three sections of grinding and classification, cyanide leaching and magnetic separation, specifically carried out according to the following steps:
[0028] (1) Grinding and classifying section:
[0029] Add 30kg / t of lime powder to the original oxygen-sulfur mixed ore, and send it to the semi-autogenous mill by the ore feeding belt. The semi-autogenous mill crushes the oxygen-sulfur mixed ore and makes the lime powder evenly mixed in the ore. The semi-autogenous mill discharges ore and adds water to become coarse ore pulp, which is transported to the cyclone group by the mortar pump for classification. The sand settling in the cyclone group enters the ball mill for secondary grinding, and the ore discharge of the ball mill of the secondary grinding is combined with the discharge of the semi-autogenous mill, and the mortar is pumped to the cyclone for classification again. The second-stage gr...
