The flotation process is an ore concentration step, which requires using about 50–85% of water in the feed pulp. With that, in flotation alone, water consumption reaches an average of 0.96 m 3 per ton [5], [6], [7].However, despite great criticism, the flotation stage is how fine-grained ores (between 10 µm and 150 µm in hematite/quartz flotation) with low purity are …
