The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability ...
1. Introduction. Flotation routes play an important role in iron ore concentration. The reverse cationic flotation is the most used technique in beneficiation of iron ore and the most commonly reagents are starch, as hematite depressant, and etheramine as quartz collector and frother.

Feb 01, 2005· Corn starch has been used in iron ore flotation in Brazil since 1978. The trade name of the reagent was Collamil, consisting of a very fine and very pure product. The amylose plus amylopectin content reached 98% to 99%, dry basis, the balance being represented by minor contents of fibres, mineral matter, oil and proteins.
Dec 12, 2015· Iron ore flotation usually requires grinding of the ore to a particular size smaller than 149 µm 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.
is the preferred option in the iron ore mining sector in Brazil. During the flotation process, the hematite is adsorbed by . starch molecules in the lower part of the flotation machine and follows the water flux as concentrated pellets, while the amine is adsorbed onto the quartz surface, forming the frother. The latter

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%.
