The flotation cells were run at different froth depths for this test, as recorded in the published dataset. The model was adjusted to represent this froth depth. Due to the water recovery not being included in the flotation model it was input as a fixed parameter in the form of solids percentage of the concentrate streams.

Due to the limitation of freshwater sources and increasingly stringent disposal standards [13, 74, 79], the minerals industry has attempted to increase water use efficiency, reduce freshwater utilization, and minimize water discharge, or seek alternatives to fresh water [57, 59, 78, 84, 101].It is widely accepted that flotation is the most …

The flash flotation cell is particularly important in the gold and silver concentration process (in liberated particles below 100 µm and associated with other minerals). These particles are not sorted into the hydrocyclone overflow, remaining in the mill–hydrocyclone system as a circulating load due to their high density (Mulleneers et al ...

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …

This has allowed a flotation cell to be modelled using the chemical reactor analogy; whereby the removal of solids from the pulp phase is defined by a first order rate equation. This means a bank of cells can be approximated by perfectly mixed CSTR's in series (Gaudin, 1957, Niemi and Paakkinen, 1969, Atkins et al., 1986, Yuan et al., 1996).
