摘要
广西某铅锌多金属硫化矿使用氰化物作为铅锌分离抑制剂,导致环境污染严重。针对该问题,研究开发出以三硫代碳酸盐为亲固基的新型有机抑制剂D1,通过浮选试验研究其作用效果,并根据接触角、吸附量及Zeta-电位检测结果,对其抑制机理进行分析。结果表明:抑制剂D1通过化学吸附的方式吸附在铁闪锌矿表面,使得矿物表面电位负移,同时减小矿物表面接触角,对铁闪锌矿具有明显的抑制作用。
A lead-zinc polymetallic sulfide ore in Guangxi used the prussiate as an inhibitor for lead-zinc separation, causing seri- ous environmental pollution. Aimed at the problem, a new organic inhibitor D1 taking the trithiocarbonate as function groups was developed, and its effect was studied by flotation tests. Besides, its inhibition mechanism was analyzed based on the contact angle, the adsorption capacity and the Zeta-potential detection. The results showed that the inhibitor D1 absorbed on the surface of marmatite through chemical adsorption, which could make the potential on the surface of mineral move to negative electrode and reduce the surface contact angle. Therefore, the new inhibitor D1 had a significant inhibitory effect on the marmatite.
