摘要
高氟铍矿石在熔炼过程中配入氢氧化铝来脱除其中的氟。结果表明,在配入5%Na2CO3、9.3%Al(OH)3、1 400～1 500℃熔炼20min的情况下,BeO回收率达到96%以上,脱氟效果良好(铍玻璃F/BeO能控制在15%以内)。为高氟铍矿石的工业应用探索出新的冶炼途径。
Defluorination with addition of aluminum hydroxide in smelting process of high fluorine bearing beryllium ore was investigated. The results show that BeO recovery is above 96% under the conditions in- cluding dosage of Na2CO3 of 5%, dosage of Al（OH）3 of 9.3%, smelting temperature of 1 400-1 500 ℃, and time of 20 min. Defluorination effect is fine in that the ratio of F/BeO of beryllium glass could be con- trolled below 15%. This new smelting process facilitates the industrial application of high fluorine bearing beryllium ore.
