Collectors, some of the most important reagents used in the froth flotation process, are used to modify the surface properties of minerals to control how they float. They selectively bind to the surface of target minerals and impart hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.
The valuable product from a mineral processing plant. Concentrator: A plant where mineral processing takes place – also called a mill. Conditioner: A tank, usually agitated by an impeller, used to allow mineral particles to react with reagents. Controlled Variable: Variable that the controller tries to maintain at set point: Coriolis Meter
The froth flotation process typically involves a series of multiple flotation cells arranged in a sequential manner. This configuration allows for a step-wise separation of valuable minerals from the ore, with each cell playing a specific role in the overall process [].The use of multiple cells in series enhances the efficiency of the flotation …

The non-polar group creates the hydrophobic surface in contact with the water. The mechanism of mineral–collector bonding depends on the collector type and mineral surface nature and charge, and can result in the collector being physisorbed or chemisorbed (Bradshaw, 1997). Sulphide minerals are semi-conductors, i.e. they can …

Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are …
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to …
Although most of the xanthates added to the flotation circuits are adsorbed by target minerals, about 50 % of the xanthates remain in the discharged tailings pulp, with concentrations ranging from 5.0 to 40.0 mg/L (Rezaei et al., 2018, Tan et al., 2021, Zhou et al., 2021b).Xanthates can escape into the environment from mineral processing, for …
The floccule generated during flocculation process is called flocculate, which exists in loose reticular aggregated state. Main applications of flocculant are as follows: (1) It is used as flotation flocculant that realizes selective flocculation, so the fine particles of target mineral are aggregated and then collected by a collector so that they rise, which …
