The flotation reagents of kyanite minerals are shown in Table 1. It can be seen from the table that the flotation collectors of these three minerals are universal and can be classified into three categories: (1) carboxylic acid collectors such as oleic acid (sodium), oxidized paraffin soap, rouge, tal Oil or the like; (2) a hydroxysulfonate and a hydroxysulfate such as sodium petroleum sulfonate; and (3) an alkylamine. Table 1 Flotation agents of kyanite minerals
| mineral | Collector | pH value | Conditioner |
| Kyanite | Sodium petroleum sulfonate sodium oleate | 2.2～4.0 9.5 5.5～7.0 3～12 | HF, H 2 SO 4 water glass, citric acid |
| Sillimanite | Sodium alkane sulfonate + oxidized paraffin soap (1:2) oleic acid sodium dodecyl sulphate sodium dodecyl acetate | 8～9 8～9 5.4 9.0～9.5 | Na 2 CO 3-carboxylic acid, sodium hexametaphosphate, sodium silicate, the CMC |
| Andalusite | Sodium oleate | 3~10 3~9 |
Commonly used in production are the first two types of collectors. When using carboxylic acid collectors, the pH of the pulp is often alkaline. It is customary in China to use alkali flotation; when using sulfonate as a collector, the pH of the slurry The value should be adjusted to acidity, also known as acid flotation.
