The kinetics of reversible complex formation of Ni-II, Co-II and Cu-II with the pentaammine(nitrilotriacetato)cobalt(III) ion, [Co(NH3)(5)(H(2)nta)](2+) (H(3)nta = nitrilotriacetic acid) have been investigated at 0.0025 ...

Low temperature isothermal kinetic studies were performed on alkali roasting of Cr2O3 with progressive replacement of Na2CO3 in the reaction mixture by NaNO3 in the temperature range of 573 to 873 K. The influence of the ...

Background/aims: in the treatment of the Malanjkhand copper ore, the oxide component remains unaffected and either goes to tailings or is separately stockpiled for future treatment by hydrometallurgical route. To overcome ...

Preparation of different grades of zirconia from zircon have been investigated. Zircon sand was thermally dissociated in a non-transferred extended are inflight thermal plasma reactor. Plasma dissociated zircon (PDZ) was ...
