摘要

USE OF CHELACATION EXCHANGER, PROCESS FOR THE PRODUCTION OF METALS FROM ITS ORES, PROCESS FOR THE PRODUCTION OF PICOLINAMINE GROUPS CONTAINING CHELING RESIN AND THE PICOLINAMINE GROUP CONTAINING CHELING RESIN The present invention relates to the use of chelating resins in monoporous metals in monodispersed metals. hydrometallurgical processes, in particular in pulp resin processes. According to the invention, mono-dispersed macroporous chelation resins have an average bead diameter in the range of 0.35 to 1.5 mm, preferably 0.45 to 1.2 mm and particularly preferred from 0.55 to 1, 0 mm. The application also features a process for preparing mono-dispersed macroporous chelation resins having weak base groups, in particular picolinamino groups. Monodispersed chelation resins are capable of removing, for example, nickel and cobalt ions in relatively large amounts of a leach suspension such as heterodispersed chelation resins.
