QUALIFICATION & PROFESSIONAL DEVELOPMENT

January 2010-Dec 2014   PhD Degree of Engineering- The university of Melbourne, Australia

A four years research degree, researching improved techniques for gold extraction from complex ores. Complexes involving a wide range of different gold-ligand interaction strengths including chloride, thiourea and thiosulphate are brought into contact with framework (quartz and feldspar) and layer silicates (kaolinite and pyrophyllite). Experimental data are correlated with information obtained from computational chemistry, to identify trends in their tendencies to associate with silicates and provide a fuller understanding of the role of silicates in gold processing.

March 2004 Master Degree of Mineral Processing Engineering- Tehran University, Iran

A two years course degree, which covered process mineralogy, mass balance calculation, flowsheet design and development, flotation and new technologies in mineral processing. A one-year research project was submitted as a part of degree entitled "Gold extraction form Zarshuran gold mine in Iran".

September 2001 Bachelor Degree of Engineering in Mining Engineering- Amir Kabir University, Iran

It  was  a  four  years  course  degree  covered  geology,

petrology,  exploration,  extraction  and  mineral

processing.  Course  work  was  covered  through  theory  and  practical

experiments  with examinations

and a one-year  project submitted for final evaluation

and the end of

the program.
