RICARDO-RIVERON, Aymara  y  ROJAS-VARGAS, Armando. Drying Rate of Carbonate of Nickel. RTQ [online]. 2014, vol.34, n.2, pp.135-144. ISSN 2224-6185.

In the present work, the drying rate of carbonate of nickel was studied experimentally at the laboratory scale. The values of critical moisture are shown and the graphics: characteristic curve of drying rate and the moisture dependence of the time. Models ware obtained to estimate the slope of the constant - rate period and to the falling - rate period until the equilibrium humidity, in dependence of external factors: drying temperature, initial moisture and the pH of the slurry. The chemical composition of the carbonate didn't exercise effect statistically significant over the drying rate.

Palabras clave : drying rate; pH; carbonate of nickel.
