Method and arrangement for enhancing use of reactor volume in connection with hydrometallurgical leaching

摘要

pThe 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.
