摘要：
The nodule was crushed to 250 mesh and leached with 1. 0 N hydrochloric acid in the temperature range 30 to 70 degree C. The rate can be represented by the volume reaction model. The leaching rate of Ni and Cu are the second order For the soluble portion of Fe, the leaching rate is also second order. The leaching behavior of Co is analogous to that of Mn. The leaching rates of Co and Mn at 70 degree C are also second order. The apparent activation energies for Cu, Ni and Fe leaching are 41. 2, 81. 1 and 43. 3 kJ/mol, respectively. The overall reaching rates appear to be controlled by the heterogeneous reaction.
