This process usesstarch (depressant) and amine (quartz collector) asreagentsto promote the separation of the contaminant mineral (quartz) from the iron-bearing mineral. The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener.

In the processing of metal ores (not including iron ore), the suspensions from mineral processing generally have70 – 80 % water content. That is, for example, from 100 000 t/d tailings, around 75 000 t/d are water and 25 000 t/d solids. In thickeners, the sludges are reduced to residual moisture contents of 40 – …
