Hematite recovery was feasible at a pH of around 3. In microflotation tests, the iron grade and recovery reached approximately 37% and 30%, respectively. These values increased in batch flotation circuits, specifically in the cleaner stage, the iron grade reached approximately 44% and the recovery was approximately 65%

Dec 12, 2015 Iron ore flotation usually requires grinding of the ore to a particular size smaller than 149 m to achieve liberation. In general the following strategies can be used for iron ore flotation. 1. Reverse cationic flotation of quartz. 2. Direct flotation, in which iron oxide minerals (hematite) are floated using anionic collectors. 3
