作为研究金属硫化物直接电解的一环,著者对黄铜矿和石墨的混合物阳极的溶解行为进行了研究。本文首先调查石墨混合率、电极电流密度、电解液 pH等对电极溶解的影响,并对阳极反应机理进行了研究。实验方法:使用的阳极試料是以 CuFeS_2为主要成分的粒度为-170网目的铜精矿和粉末石墨的混合物,以一定压缩度把它充填进图1所示之阳极室内。阳极开口断面积为10厘米~2,开口部的隔膜用化学纤维 As part of the study of direct electrolysis of metal sulfides, the authors studied the dissolution behavior of the anodes of a mixture of chalcopyrite and graphite. In this paper, the effects of graphite mixing ratio, electrode current density and electrolyte pH on the electrode dissolution were investigated. The anode reaction mechanism was also investigated. Experimental method: The anode material used was a mixture of copper concentrate having a particle size of -170 mesh and graphite powder with CuFeS 2 as the main component, and was filled into the anode chamber shown in Fig. 1 with a certain degree of compression. Anodic opening cross-sectional area of ​​10 cm ~ 2, the opening of the diaphragm with chemical fibers
