通过测试交联壳聚糖包膜处理后的黄铁矿物表面润湿性的改变以及采用扫面电镜和红外光谱等表征方法,证明在样品矿物表面形成了一层保护膜;通过采用加速浸泡法处理包膜前后的黄铁矿,探讨钝化剂浓度、pH、氧化条件等因素对钝化效果的影响,结果表明与空白样相比,经包膜处理的黄铁矿的化学氧化程度降低了50%~70%。
By testing the cross-linked chitosan coated pyrite surface wettability changes and the use of scanning electron microscopy and infrared spectroscopy and other characterization methods to prove that the sample mineral surface formed a protective film; through the use of accelerated immersion The results showed that the degree of chemical oxidation of the pyrite after the coating treatment was lower than that of the blank sample 50% to 70%.
