  • MODEL BASED PREDICTIVE CONTROL OF A ROUGHER FLOTATION ...

    Rougher flotation is the first stage in the concentration of low grade minerals and its goal is to maximize recovery, keeping the concentrate grade within acceptable ranges. Good control at this stage is important because it directly affects the performance of the concentrate operation, and small increases of even 0.5% recovery in rougher ...

  • Copper–molybdenum ores flotation in sea water ...

    Laboratory rougher flotation tests were conducted with two samples of Cu–Mo ores in fresh water and in sea water as a function of pH. In both cases Cu recoveries were slightly lower in sea water than in fresh water for a wide range of pH (pH 7–12). Flotation of molybdenite was however strongly depressed in sea water at pH higher than 9.5.

    Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3- ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings ...
