湿法冶金工厂多采用牛胶作凝絮剂,来加速矿浆的沉淀过程。牛胶有好的效果,但价格很貴,每公斤7～8元(內蒙产)。我們曾試用麦麸代替牛胶进行了試驗,取得了良好的效果。麦麸与輕金属冶炼应用的可溶性凝絮剂—面粉有相似的地方。因此,麦麸也有吸附、凝聚胶粒和沉淀的作用。試驗溶液为某湿法冶金工厂的生产溶液,含有大量稀有金属盐类的沉淀物。含鋅40～60(克/升),比
Hydrometallurgical plants use bovine glue as flocculant to accelerate the sedimentation process of pulp. Bovine plastic has a good effect, but the price is very expensive, 7 to 8 yuan per kilogram (Inner Mongolia). We have experimented with wheat bran instead of bovine gel and achieved good results. Wheat bran is similar to soluble flocculant used in light metal smelting - flour. Therefore, wheat bran also has the role of adsorption, aggregation and precipitation of colloidal particles. Test solution for a hydrometallurgical plant production solution, containing a large number of rare metal salts of sediment. Zinc 40 ~ 60 (g / L), than
