| 1 | 混合嗜温细菌对辉钼矿中Cu、Mo和Re的生物浸出(英文)显示文摘运用响应面方法和中央复合旋转实验设计方法对辉钼矿生物浸出过程中影响铜、钼和铼浸出的一些工艺条件进行了建模与优化。基于中央复合旋转实验设计方法,考察了3个主要因素对生物浸出的影响,即料液pH值、矿浆浓度、接种体浓度,其值分别为:pH1.46~2.14,矿浆浓度0.95%~11.05%,接种体浓度1.59%~18.41%。根据中央复合旋转设计方法进行20组生物浸出实验。根据所得到的铜、钼和铼浸出率的实验结果,基于3个考察因素对其分别建立了经验公式。在实验条件范围内,根据经验公式采用二次方程对获得最大的铜、钼和铼浸出率的工艺条件进行了优化。结果表明,获得最大的铜浸出率的工艺条件为:pH=1.68,矿浆浓度0.95%,接种体浓度18.41%;在此条件下,钼和铼的浸出率分别为2.18%和24.41%。铜、钼和铼浸出率的预测结果与实验结果吻合较好。考察了生物浸出中黄钾铁矾生成对浸出的影响。 | H.ABDOLLAHI S.Z.SHAFAEI M.N OAPARAST Z.MANAFI N.ASLAN | 2013 | Transactions of Nonferrous Metals Society of China2013，23，1： | 3 |
| 2 | 从低品位铜矿石中生物浸出铜的基于响应面方法的经验模型(英文)显示文摘使用响应面方法对在摇动的生物反应器里浸出铜进行模拟和优化。采用中温细菌生物浸出低品位铜矿石,研究浸矿过程参数的影响,包括p H值、矿浆浓度、亚铁离子起始浓度。检测了浸出1、4、9、14和24天后的铜浸出率,对浸出时间对浸出率的影响进行建模。采用中心组合设计法(CCD)建立模型,以预测最佳参数值。采用二次方程建模对实验范围内浸出22天的参数进行优化,以达到最大铜浸出率。在最佳条件下(初始p H值2.0,矿浆浓度1.59%,亚铁离子浓度为0)模型预测的铜浸出率为85.98%,这非常接近实验结果(84.57%)。对p H值和矿浆浓度之间以及p H值和亚铁离子浓度之间的相互作用的影响进行研究。结果显示,亚铁离子起始浓度和矿浆浓度之间没有明显的相互作用,而且发现在最佳p H值和矿浆浓度下,铜的浸出率与亚铁离子起始浓度值没有关系。 | M.YAGHOBI MOGHADDAM S.Z.SHAFAEI M.NOAPARAST F.DOULATI ARDEJANI H.ABDOLLAHI M.RANJBAR M.SCHAFFIE Z.MANAFI | 2015 | Transactions of Nonferrous Metals Society of China2015，25，12： | 2 |
| 3 | Effect of galvanic contact on the flotability of galena in the presence and absence of a collector显示文摘In this paper,the effect of various electrochemical environments in the galena flotation is investigated.The electrochemical environments consisted of a ball mill for grinding of galena ore and a Denver flotation cell for flotation of galena in the laboratory scale.In order to achieve the maximum recovery with sodium hyposulfite,the concentrations of 0.06 and 0.12 M of air and nitrogen gases have been used to control the pulp potential in the Denver flotation cell.The galena sample was from the ''Era mine'' which is located in the Kiyasar area,north of Iran.This mine contains:Galena(PbS) at least 22%,Fluorite(CaF 2) 73.37%,Quartz(SiO 2) 2.54% and other minerals such as Cerussite(PbCO 3) and Kaolinite(Al 2 Si 2 O 5(OH) 4).Flotation of Galena was conducted in a 0.12 M of sodium hyposulfite solution.It was found that the amount of recovery by this process was 85% and 63% in the presence and absence of potassium amyl xanthate(KAX) and at an estimated potential of 280 to 350 mV respectively while the recovery was 70% and 52% at an approximate potential of 175 to 210 mV in water in the presence and absence of collector(KAX). | M.B.Eslami Andargoli S.Jannesar Malakooti F.Doulati Ardejani H.Abdollahi | 2012 | International Journal of Mining Science and Technology2012，22，5： | 1 |
