METHOD AND ARRANGEMENT FOR ENHANCING USE OF REACTOR VOLUME IN CONNECTION WITH HYDROMETALLURGICAL LEACHING.

摘要

2112057PC 17 (57) ABSTRACT The invention relates to a method for enhancing reactor volume use in a leaching stagein a hydrometallurgical process. According to the method, a concentrate or cal- cine leaching stageis carried out primarily using a plurality of reactors arranged in series, one or more reactors being provided with liquid-solid matter separation and the sepa- rated solid matter being transferred to one of the reactors in the leaching stage.
