New designs of flotation machines have been implemented to treat two basic functions of flotation, i.e. attach particles to bubbles and separate bubble-particle aggregates from pulp, individually to achieve an overall improvement in machine performance (Jameson, 1988). This is well represented in the configuration of Jameson …

7 Factors Affecting Froth Flotation Process - JXSC Machine
WhatsApp: +86 18221755073
In the 1950s, the opinion was often expressed that the mechanically-agitated machine forms the best rougher and a pneumatic machine the best cleaner, the reason being that the former type has come to be regarded as one that yields a heavily-mineralized froth, which, though giving a good recovery of the minerals, is likely to be of low grade …

Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means …

Flotation of fine particle (<37 μm) and ultrafine particle (<8–13 μm) is a key challenge. Feed in flotation consists of wide range of particle size, therefore, flotation column needs to have wider bubble size to target fine as well as coarse size particles [13, 14]. So, flotation of fine particles is one of the major challenging tasks.
