PROCESS FOR PRODUCTION OF NICKEL CARBONATE

摘要

The present invention refers to a process for production of nickel carbonate comprising the following steps: a) Preparing a magnesium salt solution; b) Contacting said solution with a stream of gaseous CO2, keeping pH between 4 and 10 and temperature between 0 and 100°C, during up to 5 hours; c) Contacting the mixture of step b) with a nickel sulphate solution, producing a mixture; d) Performing a separation of liquid and solid portions of said mixture; e) Feeding step a) with said liquid portion. This process recycles the reagent used for producing nickel carbonate and yields a final product that is easy to handle and transport.
