The high intensity zone within the Jameson Cell is the downcomer. It is largely external and separated from the flotation tank. This, together with operation of the downcomer under vacuum, rather than at elevated pressure and the absence of moving parts, allows ready access to the high intensity zone for measurement and analysis. Experimentation was conducted allowing measurements of recovery ...
The flotation machine must perform a series of complicated functions. Some of the more obvious are: 1. Good mixing of pulp. To be effective, a flotation machine should maintain all particles uniformly in suspension within the pulp, including those of relatively high density and/or size.
Dec 26, 2019· As a result, the residence time of the pulp in the flotation machine will be extended or shortened. Therefore, the pulp concentration indirectly affects the ore recovery rate and concentrate grade by affecting the froth flotation time. 2. Indirectly affect froth flotation by affecting the volume concentration of the froth flotation agent.
Dec 15, 2016· Both mineral and gangue recovery increases with increasing aeration rate. As shown here from an example taken from tests on the Merensky PGM ore from in South Africa. The graphs show platinum group metals as PGMs and gangue recovery with flotation time at six different air rates measured as cubic meters of air per minute per cubic meter of pulp.
What has since become known as the "SMAP-type flotation machine" was later refined by Gary Crawford (1.983:53), who improved the means for sludge disposal and experimented with frothing devices to ameliorate flotation recovery rates. The machine described here builds on Crawford's refinements and operates on the same basic principles but is ...
The flotation recovery of these relatively large particles is often very poor; hence vast quantities of fine coal are lost in flotation tailings. Thus there is an argument that 0.5 mm is too coarse for efficient flotation, which means that a fine stream becomes applicable, say between 0.20 and 1.0 mm.
