A floatability of tantalum and niobium ore Tantalum and niobium-containing tantalum and niobium are mainly mineral iron ore and pyrochlore. The strontium iron ore is called strontium iron ore, and it contains strontium iron ore. Lanthanite and pyrochlore can be collected by cationic collectors or by anionic collectors. The flotation effect is better with a complex collector (such as sodium hydroxy citrate). Using oleic acid as a collector, the barium is best at pH 6-8, and the coltan and coltan are inhibited in the acidic medium, while quartz , feldspar and dolomite are in any The floatation is not good at pH. Therefore, when the pH is 6-8, oleic acid is used as a collector, and the gangue is easily separated from the gangue such as quartz. After treating the antimony ore with 10% acid (sulfuric acid), it becomes very 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. When oleic acid is used as a collector and the concentration of sodium sulfide is 10-20 mg/L, the antimony ore and part of the gangue can be suppressed. When a cationic collector is used, sodium sulfide initially activates some minerals such as antimony ore, but as its amount is increased, the same yield of antimony ore will decrease. When lanthanum is used to capture antimony ore, a small amount of sodium fluorosilicate can suppress all minerals. Flotation of B antimony ore Fine-grained antimony ore, commonly used in flotation and combined processes. When tantalum and niobium ore in the ore, pyrochlore, apatite calcite and the like, can gangue minerals to float, then the floating tantalum and niobium ore and pyrochlore. The gangue mineral flotation is carried out in an alkaline medium, using water glass and ammonium sulfate as inhibitors, and oleic acid as a collector. In flotation of antimony ore, in the acidic medium, sodium hydrocarbyl sulfate is used as a collector, or oleic acid is used as a collector in a neutral medium. When there are antimony ore, mica , spodumene and other minerals in the ore, it is necessary to remove the mud first, and then float the mica with a cationic collector. After the tailings are treated with alkali, mixed flotation is carried out, and the tailings are discarded. The concentrate is treated with acid and then subjected to flotation flotation, and sodium sulfate is added to select and sweep in the acidic slurry. The concentrate is an antimony concentrate, and the tailings are spodumene and other minerals.
