| 2 | 采用响应面方法和中心复合旋转设计对低品位锰矿浸出过程建模与优化(英文)显示文摘采用实验设计软件对从低品位锰矿中浸出提取锰的过程进行优化。在中心复合响应面实验设计中,考察了4个主要影响浸出过程的参数,即硫酸浓度、草酸浓度、浸出时间和温度。将锰和铁的浸出率作为考察指标。采用统计分析和方差分析确定了最优条件,即最高的锰和铁浸出率、最短的浸出时间和最低的温度。结果表明,硫酸浓度是影响浸出过程的最显著的参数,在最优条件下:硫酸浓度7%,草酸浓度42.5g/L,浸出时间60min,反应温度65℃,锰和铁的浸出率可分别达到93.44%和15.72%。 | Dariush AZIZI Sied Ziaedin SHAFAEI Mohammad NOAPARAST Hadi ABDOLLAHI | 2012 | Transactions of Nonferrous Metals Society of China2012，22，9： | 5 |
| 3 | Removal of copper from molybdenite concentrate by mesophilic and extreme thermophilic microorganisms显示文摘Mixed mesophilic and extreme thermophilic bioleaching were evaluated to remove copper from the molybdenite concentrate.Bioleaching tests were carried out in shake flasks and in a 50-L bioreactor.The shake flask tests were performed with different inoculum size,solids density,pH.and temperature in order to identify optimum conditions.The highest amount of copper elimination,75%was obtained with extreme thermophilic microorganisms(at 12%inoculation,10%solids,65℃and a pH of 1.5).The highest copper elimination by mesophilic microorganisms was 55%(at 12%inoculation,5%solids,30℃at pH 2).The optimum conditions in shake flask tests were applied to 7 days batch tests in a50-L bioreactor.Extreme thermophilic experiment gave the best copper elimination of 60%(at 12%inoculation,10%solids,65℃and pH 1.5).Mesophilic test removed 50%of the copper(at 12%inoculation,10%solids,35℃at pH 2). | Abdollahi Hadi Manafi Zahra Shafaei Sied Ziaedin Noaparast Mohammad Manafi Moorkani Navid | 2013 | International Journal of Mining Science and Technology2013，23，6： | 4 |
| 4 | Advances in reduction of NO_x and N_2O emission formation in an oxy-fired fluidized bed boiler显示文摘Fossil fuel combustion is one of the major means to meet the mounting global energy demand. However, the increasing NO_x and N_2 O emissions arising from fossil fuel combustion process have hazardous effects. Thus, mitigating these gases is vital to attain a sustainable environment. Interestingly, oxy-fuel combustion in fluidized bed for carbon capture and minimized NO_x emissions is strongly sustainable compare to the other approaches. It was assessed that NO_x formation and fuel-N conversion have significant limitation under oxy-fluidized bed compared to air mode and the mechanism of NO_x formation is still deficient and requires further development. In addition, this review paper discussed the potential of primary measure as low emission process with others supplementary techniques for feasible NO_x reduction. The influences of combustion mode, operating parameters, and reduction techniques such as flue gas recirculation, oxygen staging, biomass co-firing, catalyst, influence of fluidized bed design and structure, decoupling combustion and their merges are respectively evaluated. Findings show that significant minimization of NO_x emission can be achieved through combination of primary and secondary reduction techniques. | Khalid El Sheikh Mohammad Jakir Hossain Khan Mahar Diana Hamid Siddhartha Shrestha Brahim Si Ali G.A.Ryabov Lya A.Dolgushin Mohd Azlan Hussain Tatiana V.Bukharkina Elena A.Gorelova | 2019 | Chinese Journal of Chemical Engineering2019，27，2： | 2 |

| 6 | Designing paste thickeners for copper flotation tailings,using bed depth scale-up factor显示文摘Aim:The paste thickener could increase the water recovery and reduce the environmental impacts in tailings dam.The present work aimed to find the appropriate scale-up factor for bed depth to design paste thickener for copper tailings,using a lab glass cylinder and an operating pilot column.The thickening tests were carried out on the flotation tailing samples obtained from the Sarcheshmeh and Miduk copper mines located in Iran.Based on the industrial conditions,the values of influential parameters for paste thickener used in these experiments were pH=11 and feed solid=10%.Flocculant type was NF43U and used as 25g/t with dosage of 0.25 g/lit.The unit area of Sarcheshmeh and Miduk paste thickeners were designed as 0.057 and 0.047m2/t/day,respectively.Based on the dry feed rates to each paste thickener as 7920 and 4320 t/day,the thickener's diameters were determined as 23.9 and 16.1 meters which are similar to the actual thickener’s diameters(24 and 16 meters),respectively.In addition to unit area,the bed depth is also important in the paste thickeners design.Hence,the ratio of industrial to lab unit bed volume for Sarcheshmeh paste thickener was obtained 75 which was equal to the ratio of industrial to lab bed depth(bed depth scale-up factor exclusively for copper flotation tailings).This procedure was validated by using the Miduk sample.The bed depth in the paste thickeners was determined as 7.5 meters,by using the bed depth scale-up factor which was comparable to the actual bed depth(8 meters).This research confirmed that the bed depth scale-up factor is able to correctly determine the bed depth of industrial paste thickeners for copper tailings. | Majid Unesi Mohammad Noaparast Sied Ziaedin Shafaei Esmaeil Jorjani Mahdi Yaghobi Moghaddam Hadi Abdollahi | 2018 | Nanoscience & Nanotechnology2018，2，1： | 1 |
| 7 | Kinetics of magnetite oxidation under non-isothermal conditions显示文摘Oxidation of magnetite concentrates,which occurs during the pellet induration process,must be deeply understood to enable the appropriate design of induration machines.In the present paper,the kinetics of the magnetite oxidation reaction was studied.Primary samples were obtained from the Gol-e-Gohar iron ore deposit.Magnetic separation and flotation decreased the sulfur content in the samples to be approximately 0.1wt%.Thermogravimetric analysis was used to measure mass changes during the oxidation of magnetite and,consequently,the conversion values.The aim of this study was to use isoconversional methods to calculate the kinetic parameters.The Coats–Redfern method was also used to obtain the activation energy.Thermogravimetric analyses were run at three different heating rates.The Coats–Redfern results were too ambiguous for a meaningful interpretation.In the case of the isoconversional method,however,the mean activation energy and pre-exponential factor of the oxidation reaction were obtained as 67.55 kJ and 15.32 × 10~8 min^(-1),respectively.Such a large activation energy implies that temperature strongly affects the reaction rate.The oxidation reaction exhibits a true multi-step nature that is predominantly controlled by chemical reaction and diffusion mechanisms. | Aref Sardari Eskandar Keshavarz Alamdari Mohammad Noaparast Sied Ziaedin Shafaei | 2017 | International Journal of Minerals,Metallurgy and Materials2017，24，5： | 1 |
