Nik Syahira Nik Alias Effect of the time taken on the performance of fabricated gas–solid fluidized bed column for the separation of rare earth elements / Nik Syahira Nik Alias Kuantan, Pahang : UMP, 2014 xvi, 52 p. : ill. ; 30 cm. + 1 CD-ROM Faculty of Chemical & Natural Resources Engineering Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2014 Bibliography : p. 48-52 A gas–solid fluidized bed separator used for the separation of rare earth elements (REEs) from printed circuit board was design and fabricated. In this work, the effect of time taken on the performance of the fabricated gas-solid fluidized bed column for the separation of rare earth elements was study. Waste from electronic devices was grinded to powder forms with the particles sized less than 1.0 μm were used in this study. Beds column with different heights of sampling port were analyzed at 10 cm, 20 cm, and 30 cm while the air pressure was 15 psi, 20 psi and 25 psi were tried in this investigation. The rare earth elements were subsequently analyzed by float–sink testing. The results showed the weight percent of the fine powder increases with increasing the time taken for collecting the sample. However, the separation density decreased with increasing the sampling port height of the column Membrane separation Fabrication http://ecollib.ump.edu.my/9670/ Access in library only 0 0 0 1 10000 10000 2019-09-04 0 TP248.25.M46 S93 2014 r Bc. 0000092088 2019-09-04 00:00:00 1 2019-09-04 PSM 0 0 0 1 10000 10000 2019-09-04 0 CD 8649 | TP248.25.M46 S93 2014 r Bc. 0000092089 2019-09-04 00:00:00 1 2019-09-04 PSM VIRTUA40 5704 5710 VTLSSORT0080*0200*0400*0900*1000*2450*2600*3000*5000*5020*5040*5200*6500*6501*8560*9992
