Volume 12, Issue 4 , October 2021, , Pages 1029-1040

https://doi.org/10.22044/jme.2021.11054.2082

Abstract
  In this research work, the solubility of sphalerite concentrate due to mechanical activation in planetary ball mill in both the wet and dry modes is investigated, and the parameters of mean particle size, BET specific surface area, SEM, and XRD are analyzed. The results of the particle size analysis ...  Read More

Characterization of microstructural changes of mechanically activated ilmenite

H. Ebadi; P. Pourghahramani; B. Nemati akhgar

Volume 12, Issue 2 , April 2021, , Pages 515-528

https://doi.org/10.22044/jme.2021.10720.2033

Abstract
  Structural changes of mechanically-activated ilmenite during milling by a planetary mill are monitored and determined as a function of the milling time. The maximum specific BET surface area of 10.76 m2/g is obtained after 150 min of milling. The results obtained indicate that agglomeration of the particles ...  Read More

Volume 10, Issue 3 , July 2019, , Pages 763-776

https://doi.org/10.22044/jme.2019.8257.1700

Abstract
  In this work, the effects of temperature, acid concentration, and mechanical activation on dissolution of ilmenite were studied using the statistical design of experiment technique. Mechanical activation was carried out using a planetary ball mill in dry mode, and the resulting structural changes were ...  Read More

Mechanical activation of phosphate concentrates to enhance dissolution efficiency of rare earth elements from a kinetic viewpoint

H. Shadi Naghadeh; M. Abdollahy; A. Khodadadi Darban; P. Pourghahramani

Volume 10, Issue 2 , April 2019, , Pages 373-388

https://doi.org/10.22044/jme.2019.7658.1620

Abstract
  The Esfordi phosphate concentrate mainly contains fluorapatite, monazite, and xenotime as rare earth element (REE) minerals, accounting for 1.5% of rare earth metals. The monazite and xenotime minerals are refractory and their decomposition is only possible at high temperatures. Thus mechanical activation ...  Read More
