The coltan and pyrochlore can be collected by a cationic collector , and an anionic collector can also be used. The flotation effect is better with a complex collector (such as sodium hydroxy citrate).

Using oleic acid as a collector, the strontium ore is best in the pH range of 6-8, and the coltan and coltan are inhibited in the acidic medium, while quartz , feldspar and dolomite are The planktonic properties are not good at any pH. Therefore, when pH=6~8, using oleic acid as a collector, it is easy to separate the bismuth ingot from the gangue such as quartz.

After treating the antimony ore with 10% acid (sulfuric acid), it becomes easy to float. With the increase of the amount of acid, the floatability of the antimony ore is increased, and the effect of using sulfuric acid is better than that of using hydrochloric acid. Treatment with 1% hydrofluoric acid is similar to sulfuric acid. Using oleic acid as a collector, the concentration of sodium sulfide is 10-20 mg / liter, which can inhibit bismuth ingot and part of gangue. When a cationic collector is used, sodium sulfide initially activates some minerals such as antimony ore, but as its amount increases, the recovery of antimony ore decreases. When lanthanum is used to capture bismuth ore, a small amount of sodium silicate can suppress all minerals.
