| 1 | Structural, compositional and mineralogical characterization of carbonatitic copper sulfide: Run of mine, concentrate and tailings显示文摘The aim of this study was to determine the structural, compositional, and mineralogical composition of carbonatitic copper sulfide concentrator plant streams. Three samples, each from a different stream(run of mine(ROM), concentrate, and tailings) of a copper concentrator were characterized using various techniques, including stereomicroscopy, X-ray fluorescence, X-ray diffraction, Fourier transform infrared(FTIR) spectroscopy, scanning electron microscopy(SEM) in conjunction with energy-dispersive X-ray spectroscopy(EDS), and optical microscopy. The results reveal that each stream possesses its own unique compositional features. Carbonate minerals associated with calcite and dolomite, followed by quartz, remain the major minerals in both the ROM and tails streams. In the ROM stream, chalcopyrite appears to occur as veins within the carbonatite-hosting ore body. Mineral phase mutation was discovered in the tails stream because magnetite formerly identified in the ROM as the primary iron oxide had evolved into hematite. This metamorphosis was likely promoted by the concentration process. The concentration process was effective, upgrading the chalcopyrite content from 2 wt% in the ROM stream to 58 wt% in the concentrate stream; it was accompanied by bornite(4 wt%), anilite(3 wt%), and digenite(2.5 wt%). In addition, the concentrate stream exhibited properties distinctive from those of the other streams. The FTIR analysis showed the existence of a sulfide group related to the chalcopyrite mineral. Free chalcopyrite grains were observed in the concentrate by SEM analysis, and their mineral presence was supported by the EDS analysis results. All characterization techniques corresponded well with each other regarding the structure, chemistry, and composition of the samples. | Kolela J Nyembwe Elvis Fosso-Kankeu Frans Waanders Kasongo D Nyembwe | 2019 | International Journal of Minerals,Metallurgy and Materials2019，26，2： | 3 |
| 2 | 不同pH值硫酸铁溶液中碳酸盐岩型黄铜矿的浸出机理显示文摘在pH值0.5~2.5、温度25℃和时间12 h的条件下,研究碳酸盐岩型黄铜矿在H_(2)SO_(4)−Fe_(2)(SO_(4))_(3)−FeSO_(4)−H_(2)O体系中的溶解行为。实验所用的颗粒粒度为53~75μm。在所有pH条件下,Cu的回收率均低于15%。浸出渣的XRD、SEM−EDS和光学显微镜(OM)分析结果表明,溶解过程中形成了中间相。pH为0.5和1.0时的中间相分别是Cu_(3.39)Fe_(0.61)S_(4)和Cu_(2)S,而pH值为1.5和1.8时的主要矿物为Cu_(5)FeS_(4)。热力学模拟预测产物的生成顺序为CuFeS_(2)→Cu_(5)FeS_(4)→Cu_(2)S→CuS。Cu_(5)FeS_(4) and Cu_(2)S为可溶性中间相,而CuS和Cu_(3.39)Fe_(0.61)S_(4)是难溶中间相,在整个溶解过程中不断积累。所得结果表明,CuFeS_(2)浸出过程中CuS和Cu_(3.39)Fe_(0.61)S_(4)的生成有助于形成钝化膜。 | Kolela J NYEMBWE Elvis FOSSO-KANKEU Frans WAANDERS Martin MKANDAWIRE | 2021 | Transactions of Nonferrous Metals Society of China2021，31，7： | 2 |
