Modelling the Impact of Flash Flotation from Batch

Flash flotation is a process designed to remove coarse, liberated, fast floating minerals from hydrocyclone underflow. Irrespective of liberation, coarse particles would normally remain in a grinding circuit until they are reground fine enough to report to the hydrocyclone overflow.

2020-6-7  Over-grinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation Unit-Cell is used in the grinding circuit to recover a large part of the silver and lead values as soon as liberated. The flowsheet is for a plant having a capacity in the range of 300 to 500-tons per day.

Sulphide Flotation an overview ScienceDirect Topics

Unit flotation cells (Hasting, 1937; Taggart, 1945) and the more recent flash flotation cells (Kalloinen and Tarainen, 1984) are installed in grinding circuits with the purpose of improving the overall flotation recovery of free gold (Taggart, 1945; Suttill, 1990; Laplante and Dunne, 2002). The aim is to remove as much as possible of the free gold contained in the circulating load of the grinding mill before it is
