21-06-2021· The study explored a new combination amine collector (XK-28) that can obtain better flotation index and deing rate for magnetic iron ore. A pure quartz mineral test indicates that dodecylamine, XK-I, or XK-II has good collection effect on quartz and their best flotation pH is in the range of 6–7. The experimental results of a combination collector (XK-I:XK-II = 2:8.) show that the ...

The reverse flotation of iron ores is the usual process for the beneficiation of iron ores. In this case the silica particles are floated with amines. Usually this pulp, including the main part of amines, is deposited in the tailing dams. In the best case a part of the amine free water is reused as process water after a long residence time. The recycling of the water containing amines has not ...

01-05-2013· In iron ore concentration, reverse cationic flotation of quartz has been successfully employed for particles below 150 μm previously deslimed. Amine and starch are used, respectively, as quartz collector and iron oxides depressant.
Results have shown that the use of recycling water after the wastewater treatment proposed in this work led to a good performance of apatite flotation, leading to recovery (80.5%) and grade (31.2% ...
Thus, starch is playing a dual role in the reverse flotation of iron ore, acting as a depressant by hindering amine adsorption at the hematite surface in order to maintain the hydrophilic surface state of hematite, and acting as a flocculant to aggregate fine hematite particles, which if not flocculated, could diminish the flotation separation efficiency by being transported to the froth phase ...
It is well known that reverse flotation performance of iron oxides is affected by water quality. Since many potential variations among water sources recycling in a mineral processing plant bring unpredictable effects on the flotation system of iron oxides: disturbing ions/compounds, pH, hardness, residual reagents, etc. In this study, the recycled tailing water from a local plant ...
