Abstract
A flotation method for mineral processing is disclosed. The method for floating includes a first step of using a first carboxymethyl cellulose (CMC) in a first flotation cell, and a subsequent step includes using a second CMC in a subsequent flotation cell, the first and second CMCs having different characteristics. The first flotation cell may be used in at least one rougher stage and/or at least one rougher-scavenger stage of the flotation method, and the subsequent flotation cell may be used in at least one cleaner stage, and/or at least one cleaner scavenger stage, and/or at least one recleaner stage of the flotation method. A product may be obtained, directly or indirectly, by such a method. A mineral processing plant may use at least two CMCs of different characteristics in flotation for mineral processing.
