Coarse particle flotation: A review

Coarse particle flotation for early gangue rejection application has attracted considerable attention in the mineral industry. Since grinding units consume a significant amount of energy and sometimes stand as the most energy-consuming unit in the process (Curry et al., 2014, Jeswiet and Szekeres, 2016, Hassanzadeh, 2018), the early separation of gangue from …

Flash flotation for improved gold recovery at Freeport …

• a high flotation rate (kinetics) for mineral particles in the 30-100 micron (140-400 mesh) size range, and • the relative absence of gangue fines (slimes), which often degrade the flotation process. 2) Flash flotation differs from convention flotation (and unit cells) in that not all feed is kept in suspension.

A review of froth flotation control

Re-circulating material through a flotation plant results in decreased residence time of material per flotation cell, but does allow for the valuable material to spend more time in the flotation plant as a whole; and, subsequently, increases the overall recovery (Wills and Napier-Munn, 2006).

The assumption that the flotation cells are well mixed is ...
