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

http://dx.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

Leaching of gold ores with high cyanicides: a physico-chemical modeling approach

Y. Kianinia; M. R. Khalesi; M. Abdollahy; A. Khodadadi Darban

Volume 10, Issue 1 , January 2019, , Pages 87-94

http://dx.doi.org/10.22044/jme.2018.7099.1556

Abstract
  Processing of gold ores with high sulfide minerals is problematic as they consume cyanide and reduce gold leaching. Optimization of gold leaching and cyanide consumption requires a methodology to estimate the amount of exposed cyanicides, their leaching kinetics, and speciation of cyanide complexes that ...  Read More
