Research Experience
Five years research experience in the area of extraction, separation and recovery of metals.
Title of thesis: “Recovery of Nickel and Cadmium from Spent Ni-Cd Batteries by
Environmental Friendly Hydrometallurgical Route”.
Sponsored by: The Ministry of Environment and Forests, New Delhi.

Brief summary of the Ph.D thesis work

• Studies on the extraction of cadmium and nickel from chloride/sulphate leach liquors of spent Ni-Cd batteries have been carried out with organophosphorus and thioorganophosphorus extractants using hydrometallurgical process such as solvent extraction which is treated as the most efficient separation technology.
• Large scale leaching experiments were done to generate sufficient quantity of leach liquor for processing.
• Flow sheet for the processing of chloride and sulphate leach liquors of spent-batteries was developed on laboratory scale.
• Oximes such as LIX 84I have been used for the solvent extraction studies of nickel from sulphate solutions and further for the separation of nickel from copper and zinc.
• Synthesis of isoxazolones, which are potential and strong complexing reagents, was done, and the synthesized extractants have been used for the solvent extraction studies of cadmium and nickel.
Major Achievements
o In spite of the large number of studies reported on the extraction of various metal ions with Cyanex 923 and Cyanex 301 extractants, these were explored first time for the selective separation of Cd from Co and Ni for the treatment of spent battery leach liquors.
o Cyanex 301 was used for the selective separation of cadmium from cobalt and nickel from sulphate leach liquors, which can extract metal ions at lower pH values. This behavior is useful for the treatment of metals containing highly acidic aqueous solutions like the spent battery leach liquors where pH adjustment is very difficult.
o Cobalt-nickel separation factor > 4700 was achieved using Cyanex 272 as the extractant.
o The generated chloride/sulphate salts of cadmium, cobalt and nickel are in pure form and their recovery values were >99.9%.
o The data on extraction behavior of nickel with its associated metals using LIX 84I, revealed possible separation of copper and zinc at particular equilibrium pH values. Therefore a flow sheet for the selective separation and recovery of these metals using LIX 84I was developed.
o The study highlights the utility of isoxazolones as extractants for the solvent extraction studies of cadmium and nickel that have not been explored till date.
o The studies highlight the use of kerosene as diluent that is cheap and readily available.
o The results on stripping studies revealed that the metals were stripped easily with acidified distilled water and low concentrations of acids, which is an important phenomenon in any commercial extraction process, in terms of economic considerations.
o Regeneration and recycling of extractants is also another important feature in this work.
o Utilization of these batteries for metal recovery helps the user industry to reuse the spent batteries as raw material after the treatment for batteries manufacture.
o The proposed methodology helps in the conservation of natural resources and helps the environment by avoiding the contamination of soil and water with toxic cadmium.
