Y. Pyrometallurgical treatment of lead-antimony ores [J]. Tsvetn Metally, 1932, 7: 108-111. [3] TANG Mo-tang, WANG Ling. A new process for treating lead solution of jamesonite concentrate...; 1 Introduction It is difficult to separate lead and antimony from jamesonite by mineral process because they exist as sulfide solid solutions and disseminate each other[1]. In order to utilize......
was shown to accelerate the dispersion of sintering dust and transform the KCl overlay to a leachate with 20.78 g/L of K+. A lead and silver concentrate consisting of 40.82% of Pb and 0.96 kg/t of Ag was achieved, while an iron concentrate with 60.89% of Fe was gained as tailings among sulfidization flotation. The recoveries of Pb, Ag and Fe were 89.57%, 87.85% and 88.58%, respectively......
; 文献标志码:A 文章编号:1672-7207(2016)12-3982-07 Study on silicon behaviors in HCl leaching of iron concentrate recovered from zinc kiln slag... Nerin Engineering Co. Ltd., Jiangxi 330031, China) Abstract: The behaviors of silicon in the hydrochloric acid leaching of iron concentrate recovered from zinc kiln slag were investigated through both......
cooling and air cooling. Grade and recovery of iron in concentrate from rare-earth tailings cooled by water are 45.00%-49.00% and 65.00%-77.50%, respectively. Key words: rare-earth tailings; iron... et al [1] obtained concentrate with iron grade of higher than 58.21% and iron recovery of more than 79.39% by magnetic separation. It was reported that ZHANG et al [2] dealed with limonite......
to the seam floor are all within the projective plane of the rear barrier pillar and their positions concentrate on the barrier pillar adjacent to the connection corner of the second open-off cut......
adjustment agent than using CaO. Under the optimal conditions (64 g/t kerosene and 6 kg/t Na2S), satisfied recovery and grade of molybdenite concentrate can be achieved (84% and 8.2%, respectively), indicating...; 1 Introduction The flotation process for recovery of molybdenum concentrate from the primary molybdenite is usually simple since molybdenite......
transform infrared spectrum (FTIR) analysis. Flotation results show that the recovery of scheelite increases in the order of oleic acid 3, a rough concentrate containing 1.423% WO3 with the recovery... concentrate product, so the condition tests of roughing operation were carried out, and the flowsheet and the results are shown in Figure 12. With the increase of collector dosage, the WO3 grade of the rough......
的主要化学成分 Table 1 Main chemical composition of iron concentrate used in experiment (mass fraction, %) 图1 实验所用铁精矿的XRD谱 Fig. 1 XRD pattern of iron concentrate used in experiment 1.2... utilization of iron concentrate 1.3.3 喷雾热解实验 喷雾热解实验主要装置为自制的超声雾化喷雾热解炉[16],实验步骤如下:1) 将热分解炉升温至500~900 ℃,开启载流空气,并保温30 min,以确保热场均匀性.2) 将硫化沉淀后液超声雾化,使雾化后的液滴随载流空气进入炉内反应,于集料器中收集反应产物,并取样分析.实验所用雾化功率为2.0 W,载流空气......
