Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.

Lassaad Hedhili

For nickel laterite containing 0.6% Ni, the most efficient method would probably be hydrometallurgy. A common method is the HPAL (High-Pressure Acid Leaching) process, which uses sulfuric acid to extract nickel from laterite. The HPAL process is used to treat nickel laterites with low nickel content, such as those containing less than 1% nickel.

Mohammad Jafari

Dear Mr. Hedhili,

Thank you for your response. If we cannot use the HPAL process, are there any other processes like gravity separation that can be used to improve the grade of nickel from nickel laterite with good recovery?
