Leaching ores, concentrates and ashes; This process includes a variety of combinations and especially sulphides which need special care. I am also interested in selective leaching and leaching at upper temperatures. Kinetics study of leaching processes is of my interest too.

Purification of substances and especially solutions by different methods; In this area, solvent extraction merits careful consideration and I like to do research on solvent extraction either for purification or to separate and to extract two or more metals of a solution. Exploring the thermodynamics and the mechanism of the process for a better selection of reagents and reaction's parameters is of my interest. I also like to study the interaction of two extractants and the synergist effect by different methods such as FT-IR analysis.

Design and analysis of experiments and also optimization; Since hydrometallurgy experiments usually need a number of tests and applying an appropriate procedure in experiments results in more reliable data in a shorter number of runs, this area is considered in all my studies and is of my interest. Being able to model the process is another benefit of a proper design which I am currently working on it.
