研究了氧化亚铁硫杆菌在9K培养基中生长及铁的行为。以Fe2+的氧化表征氧化亚铁硫杆菌的生长特性及其活性,表明生长繁殖过程经历诱导期、缓慢期、指数期、稳定期和衰亡期。氧化亚铁硫杆菌在生长繁殖过程中,不断地将Fe2+氧化为Fe3+,同时Fe3+又发生一系列的水解反应,并生成黄铵铁矾沉淀。Fe2+的细菌氧化主要以O2为最终的电子受体。

在镍冶炼过程中产生大量的废水,其中含有镍、铜、钻等金属离子。这种冶炼废水在排放前必须加以处理,以便回收有价金属元素和防止污染环境。作者采用中和-混凝法处理镍冶炼废水,并对方法进行了热力学分析,对混凝机理进行了研究。理论计算结果表明:Ni2+,Cu2+,Co2+开始沉淀的pH值分别为7.47,6.00和7.68;若沉淀到1mg/L以下时,所控制的pH值分别为8.48,7.01和8.70。通过实验获得的最佳条件为:pH=9.0,聚合硫酸铁用量为镍含量的2倍,聚丙烯酰胺用量为4mg/L;处理后,废水中ρNi<0.13mg/L,ρC0<0.01mg/L,PCu<0.005mg/L。

The mechanism of attachment and leaching of thiobacillus f errooxidans (T. f.) on chalcopyrite were stud ied. The shaking flasks with bacteria were observed by SEM. The process of T. f attached to the surface of the mineral sample and the biofilm forming were described. The promoting role of the biofilm for bioleaching was discussed. The exis tence of Fe2+ in the exopolysaccharide layer of T. f was demonstrated by EM(electronic microscope) cell chemistry analysis. These results show that under the proper growth condition of bacteria, bioleaching of chalcopyrite results in the for mation of complete biofilm after 2 3 weeks. There are iron ions in the outer layer polymer of T. f., which provides the micro-environment for themselves, and can guaruntee the energy needed for the bacteria growth in the biofilm. At the same time, Fe3+ ions produced oxidize sulfide which brings about the increase of both growth rate of the bacterial and leaching rate of sulfide minerals.

【期刊论文】Mechanism of crud formation in copper solvent extraction

The authors investigated the mechanism of crud formation in copper solvent extraction. It is indicated that pH value of solution and the phase ratio (O A) are the main factors affecting crud formation in solvent extraction. The amount of crud extraction increases with aqueous pH value increase, and reduces with the increase of the phase ratio. Fe3+, Mg2+, fine air bubble and suspended particulates in leaching solution contribute to crud formation. One case is that a series of reactions of hydrolization and polymerization occurs for Fe3+, while pH>2.5, polyhydric complex or Fe2SO4 complex are formed. Then the complex-ions of FeOH2+, Fe2 (OH)4+ 2 cause poly-reaction, which is likely to lead emulsion. The study on Zeta potential indicates the repulsion between electriferous droplets in solvent extraction prevents phase coalescence, which is one of the major reasons for emulsion.

针对某冶炼厂氧化钴生产车间产生的废水,研究了氨对其溶液化学性质的影响,提出了采用该冶炼厂的贵金属生产车间的碱洗废水作硫化沉淀剂,联合混凝法的处理工艺方案。研究结果表明,当氧化钴生产废水与贵金属生产废水混合比例控制在10∶1以下时,不需添加硫化钠就能使废水中重金属达标排放;当比例在10∶1以上时,需添加额外的硫化钠;影响重金属残余浓度因素由大到小的顺序为:硫化钠用量、液体聚合硫酸铁用量、pH值;废水中重金属能达标排放的最佳试验方案为:硫化钠添加量为0.146g/L,液体聚合硫酸铁用量为1.596g/L,pH值控制在7.0。

【期刊论文】Bacterial oxidation activity in heap leaching①

Bioleaching of sulfide minerals by bacteria, mainly Thiobacillus f errooxidans (T. f.) and Thiobacillus thiooxidans, plays an important role in hydrometallurgy because of its economic and environmental attractions. The surveys of production process and the bacterial oxidation activity in the heap bioleaching were investigated. The results show that pH value is high, bacteria biomass and ferric concentration are low, generation time (above 7. 13h) is long in leachate, and less bacteria are adsorbed on the ores. The bacteria in the leachate exposing on the surface and connecting with mineral, have much faster oxidation rate of Fe(Ⅱ) and shorter generation time, compared with those which are in the reservoir for a long time. There is diversity for oxidation activity of Fe (Ⅱ), while there is no diversity for oxidation of sulfur. So it is advisable to add sulfuric acid to degrade pH value to 2.0, add nutrients and shorten recycling time of leachate, so as to enhance bacteria concentration of leachate and the leaching efficiency.

【期刊论文】Solvent extraction of copper and zinc from bioleaching solutions with LIX984 and D2EHPA①

The solvent ext raction of copper and zinc f rom the bioleaching solutions of low-grade sulfide ores with LIX984 and D2EHPA was investigated. The influences of ext ractant content, aqueous p H value, phase ratio and equilibration time on metals ext raction were studied. The result s show that L IX984 has a higher selectivity for copper than for iron, zinc and other metals, and has the copper ext raction rate above 97%, while the zinc and iron extraction rate is less than 1.6% respectively. Zinc ext raction is carried out following the copper ext raction f rom the raffinate. The zinc ext raction with di (2-ethylhexyl) phosphoric acid (D2EHPA) is low due to it s poor cation exchange. A sodium salt of D2EHPA is used and the zinc ext raction rate is enhanced to above 98%. Though iron (Ⅲ) is st rongly ext racted before the ext raction of zinc by D2EHPA, it is difficult to st rip iron f rom the organic phase by sulfuric acid. The zinc st ripping rate is above 99% with 100g/L sulfuric acid, while that of iron is 0.16%. Hence, the separation of zinc from iron can be achieved by the selective st ripping.

从细菌学的观点探讨了硫化矿浸出的本质和机理。从本质上来说,浸出是生命体主动获取能量的方式,不能简单视为一种“催化作用”。从微观上来看,直接或间接浸出归因于微生态中不同细菌的不同特性及其它们之间的相互作用,初级和次级反应浸出则是生命进化的表现。根据从细菌学归纳的浸出机理,作者提出浸出各种不同种类的硫化矿应选择不同种类的细菌,而育种时重点放在提高还原硫氧化酶的活性上。

采用正交实验方法,考察了矿石粒度、矿浆含量、接种量对大冶露天矿石和井下矿石的摇瓶浸出过程的影响。结果表明:粒度对露天矿和井下矿的酸耗影响大,对井下矿的浸出率影响高度显著;矿浆含量对酸耗影响大,对浸出率则不显著;在接种的初期,接种量对酸耗与浸出率都有影响,2d后接种量的影响消失;井下矿浸出的最优工艺条件为:粒度<0.154mm,矿浆含量10%,接种量10%;露天矿浸出的最优工艺条件为:粒度<0.154mm,矿浆含量20%,接种量7.5%。
