王永斌

摘 要：本报告的主要创新点是运用浮选药剂分子设计理论，结合现代有机化学合成原理提出的，专门设计用于浮选捕收剂的螯合型非离子型系列产品及自由基催化缩合合成。 研究结合现代有机化学绿色合成原理，运用现浮选药剂的分子设计理论，采用催化缩合反应，通过筛选新型催化剂，优化合成工艺，合成出具有两个以上活性官能团的高效捕收起泡剂——A-300，该药剂是一种螯合型非离子型胺乙醇黄药的衍生物，外观为黄色透明油状液体，有酯的气味，比重0.985g/mL，主成分含量≥85%。是自然铜、金以及镍、铜、铅、锌等硫化物的有效捕收剂，具有捕收力强和选择性好的双重优良属性的捕收剂，尤其对细粒级铜矿物有较强的捕收能力，对pH适应范围较广，为pH7～12。应用于铜锌矿石分选，可提高铜精矿品位及回收率，在浮选铜镍矿时可作为镍矿的捕收剂。 本研究通过将A-300与硫氮腈酯、非离子捕收剂等复配，分别得到A-6、A-9两种对铜矿物连生体有较强的捕收能力专一捕收剂。A-6对铜矿物连生体有较强的捕收能力，可大幅度提高铜矿物回收率。

Study on Synthesis Technology of water soluble and nonionic chelating collector

Abstract：This topic has been implemented in June 2008， and through the acceptance in February 2011.Within 2 years during execution， this topic has been created an more efficient collecting frother A-300. In the process of synthesis， this topic combined with modern green organic chemistry synthesis principle，using the modern theory of flotation reagents molecular design ， uses catalytic condensation reaction， through the screening of new catalyst， optimizing the synthesis process， to make the efficient collector has two or more reactive functional groups. The reagent is a kind of chelating nonionic ethanol amine xanthate derivative， whose appearance is yellow transparent oily liquid， and smells with scents of ester， the proportion of 0.985 g/mL， the main component content is no less than 85%. It is effective collector for natural copper， gold and sulfide of copper， nickel，lead and zinc.This reagent has the good double excellent properties with collecting power and selectivity， especially for fine grained copper content，it has a strong ability of collecting， and with a wide pH range， as pH7 ～ 12. Ashele Copper ore dressing experiments in xinjiang show that， In the case of guarantee grade of copper concentrate，compared to the original plan， Copper recovery rate increased by 2.65%. Through compound With Sulfur nitrogen acrylic ester，non-ionic collector，A-300 and so on， this topic get two of single-minded collector with A-6 and A-9，which has a strong ability of collecting for copper mineral. The agent of A-6 can greatly improve the recovery rate of copper mineral，which has A strong ability of collecting for copper mineral intergrowth. A - 6 instead of the original drug in copper concentrator of Saishitang and BaiNaimiao ， the remarkable technical indexes have obtained： the copper concentrate grade from 14.42% to 14.42%， copper recovery rate increased by 2.23%. Using A-9 collecting frother to replace the agent of 2# oil and butylamine in a low-grade copper and nickel ore of Yakesi in xinjiang， the ideal technical indexes are achieved： on the basis of original indexes， the recovery rate of nickel in the Copper and nickel concentrate is increased by 2.50%， copper recovery rate increased by 1.20%.

Key words：water soluble and nonionic； collector； Reactive functional groups ；fine grained copper； copper and nickel ore； the recovery rate
