研制合成了一种含芳基、羧基及磺酸基团的新型浮选药剂EM—2。该药剂与氧化石腊皂混合(称之为SLM)作捕收剂,水玻璃作调整剂,用于包头白云鄂博红铁矿反浮选萤石中,工业分流试验在原矿铁品位35.11%时,获得铁精矿品位61.10%,回收率80.31%,精矿含氟0.74%,含磷0.14%的良好技术指标。工业应用获得的生产指标为:原矿铁品位31.32%,精矿铁品位60.38%,回收率为73.43%,精矿含氟0.58%,含磷0.124%。
A novel flotation reagent EM-2 containing aryl, carboxyl and sulfonic acid groups was synthesized. The agent is mixed with an oxidized wax and soap (called as SLM) as a collector and water glass as an adjusting agent for anti-flotation fluorite in the Baiyunebo red iron ore of Baotou. The industrial diversion test is conducted at an iron ore grade of 35.11% , Obtaining a good technical index of 61.10% iron concentrate grade, 80.31% recovery rate, 0.74% fluoride content, and 0.14% phosphorus content. The production indexes obtained by industrial application are: raw ore grade of 31.32%, concentrate grade of 60.38%, recovery rate of 73.43%, concentrate containing 0.58% of fluorine and 0.124% of phosphorus.
