The flotation methods for oxidized lead minerals, such as anglesite, furnish galena, beaverite, were investigated by three methods mentioned below.Comparlng these methods by laboratory sfudies, foibwlng results were obtained.
1) By the soap flotation method, although the cost is low, the lead recovery is very low and the primary slime cannot be treated.
2) In the sulfidizing method using sodium sulphide and sodium phosphate dibasic, the lead recovery is satisfactory but the reagent cost is high.
3) In the modified method.using methyl xanthate and sodium phosphate dibasic, the lead recovery is quite satisfactory and the cost is lower than the sulfidizing method.
Following the third method, our plant operation has been very satisfactory.
