Optimization of Reverse Cationic Flotation of Low-Grade Iron ...

Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and two types ...

These tend to be soluble polymers (such as starch) that selectively coat mineral surfaces and prevent collector from attaching. An example of this is in the reverse flotation of silica from iron ore, where the silica tailings are floated using a cationic collector at a pH of 8.5 - 11, leaving behind the iron oxide minerals.

Dissolved Air Flotation System [Enhanced DAF] - Ecologix Systems

Dissolved air flotation (DAF) is a clarification process that utilizes air to remove suspended matter from the surface of treated water. DAF works by dissolving air under pressure and then releasing millions of tiny air bubbles into the water at atmospheric pressure.

Effect and mechanism of siderite on reverse flotation of ...

The effects of siderite on reverse flotation of hematite were investigated using micro flotation, adsorption tests, and Fourier transform infrared spectroscopy. The flotation results show that interactions between siderite and quartz are the main reasons that siderite significantly influences the floatability. The interactions are attributed to dissolved siderite species and fine siderite ...
