    Study on Anhydrous Ethanol Prepared by Extractive Distillation of Ethylene Glycol Experimental
    TAN Yanxia, Ll Dongli, Ll Fenrui, CHENG Yongwei
    Journal of Kunming Metallurgy College    2020, 36 (3): 101-104.   DOI: 10.3969/j.issn.1009-0479.2020.03.018
    Abstract890)      PDF(pc) (993KB)(790)       Save
    Anhydrous ethanol is widely used and has many production methods,among which extractive distillation has been paid more and more attention because of its advantages of low energy consumption, no pollution,simple equipment and convenient operation. In this paper,ethylene glycol is used as the extractant,and the process conditions for the preparation of anhydrous ethanol are optimized by using the extractive distillation device.The effects of ethanol concentration,reflux ratio,solvent ratio and other factors on the purity of the product obtained by extractive distillation were explored experimenlally ,and then the conditions of exlractive distillation were optimized by orthogonal experiment,and the best conditions were as follows:the ethanol concentration of the raw material was 90% , the solvent ratio was 2.6,and the reflux ratio was 3.Corresponding to this condition,absolute ethanol with a mass concentration of 99.62% was obtained at the top of the tower.

    Journal of Kunming Metallurgy College    2023, 39 (6): 1-.   DOI: 10.3969/j.issn.1009-0479.2023.06.001
    Abstract131)      PDF(pc) (1424KB)(251)       Save
    Aiming at a low-grade oxidized copper ore resource in Yunnan province , this paper adopts thetreatment process of sulfuric acid leaching with low investment , fast effectiveness and low pollution, andfocuses on the influence of leaching agent coneentration, mineral particle size, liquid-solid ratio , leac.hing time , leaching temperature and stirring intensity on copper leaching rate. Through the experimentalresearch , it was found that the low-grade oxidized copper ore is suitable for sulfuric acid leaching treat.ment. The optimum parameters are obtained, namely, concentration of leaching agent is 220 g/kg, themineral size is 40 mesh, the liquid-solid ratio is 3: 1 , leaching for 4 h, the leaching temperature is 60℃Cand the stirring intensity is 500 r/min. Under the conditions of the best acid leaching parameters, theleaching rate of the oxidized ore reaches 84% , the concentration of copper ion in the leaching solutionreaches 6. 9 g/L, and the grade of copper in the leaching residue is reduced to about 0. 26% . The exper-imental results make the low-grade copper resources that have not been effectively developed and utilizedin the past can be gradually developed, effectively expand the scope of copper resources, and have cer-tain economic and social benefits , providing a reference for similar mineral treatment and utilization oflow-grade copper resources.

    On Resource Potential,Distribution and Characteristics of Shale Gas in China

    JOURNAL OF KUNMING METALLURGY COLLEGE    2017, 33 (5): 17-24.   DOI: 10.3969/j.issn.1009-0479.2017.05.004

    This paper introduces the resource potential,analyzes the geological history and space distribution of shale gas in China.Then it compares the characteristics of three main types of organic-rich shale in China and studies the difference of shale between China and North America. The geological resource quantity of shale gas in China is between 80.45×1012~144.50×1012,among which the recoverable resource is between 11.50×1012~36.10×1012. Many complicated shale formations were deposited from Chuanlinggou Formation in Mesoproterozoic Erathem to Dongying Formation in Oligocene in the process of polycycle tectonic and sedimentary environment evolution in China. Marine shale,formed at early paleozoicera,is superior in resource potential and reservoir forming conditions,mainly distributed in south China's middle-lower part of Yangtze region,Sichuan Basin and central and western China's Tarim Basin,with most important stratas of Qiong-zhu-si Formation,Wu-feng&Long-ma-xi Formations.Inferiorto Marine shale,the transitional shale,developed at late paleozoicera is distributed in Carboniferous-Permian of Sedimentary basin in the mid-western China's Jung-gar Basin,Ordos Basin,Tarim Basin and Permian in South China,with importants tratas of Taiyuan,Shanxi and,Long-tanFormations.While,next to the transitionalshale,the continental shale,formedat Mesozoic and Cenozoicera,is distributed in Song-liao,Bo-haiBay,OrdosandSichuan basins,with important stratas of Yan-chang,Qingshan-kou,Sha-he-jie Formations,Triassic and Jurassic systems.

    The mine is technological expansion project,the original 600 000 t/a production scale expantion to 2. 1 million t/a.  The work was clone to take full advantage of existing eduipment,play eduipment efficiency so that a reasonable match with each other between the original eduipment and existing eduipment meet the needs of the open stope mining engineering.  It can also reduce ore loss and dilution,improve mining economic effects,so that the total amount of eduipment and mine stripping production capacity match.  Large一scale eduipment can be used.  The optimized selection of mining and transportation equipment in the open pit is a reference for similar mine equipment selection.

    Design of Multilevel Logistics Distribution Network with Splitting Order and Consolidating Deliveries
    DUAN Limei, ZHANG Jing, ZHANG Jun, ZHAN Zhihua, WANG Yidan
    Journal of Kunming Metallurgy College    2023, 39 (4): 86-.   DOI: 10.3969/j.issn.1009-0479.2023.04.013
    Abstract139)      PDF(pc) (980KB)(304)       Save
    In order to cope with the characteristics of multipleorders, small batches and multiple ware-house shipments, a new logistics strategy is discussed to design the logistics distribution network. Basedon the design problems in traditional multi-level logistics distribution network , this paper studies themulti-level logistics distribution network design with splitting order and consolidating deliveries, establishes a mixed integer programming model, and designs experiments to verify the proposed modelThrough the experiments, it is found that the proposed model can solve the studied problem effectively.that the logistics strategy of splitting order and consolidating deliveries is effective.
