Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

This work also shows the stark contrast between the "classical" residence time of the bench mechanical flotation cell test and the Jameson Cell downcomer residence time. Both achieved similar recoveries, however the downcomer residence time was approximately 4.5 s, compared to 8 min for the bench test.

In the Jameson cell slurry and air are introduced at the top which proceeds downward in the downcomer and forms a liquid jet. Consequently, air is entrained into the plunging jet because of the vacuum effect and generates a large number of tiny bubbles as a result of high shear rate [55].In the downcomer region, the collection of particles on …

The current work intends to reduce this gap by emphasizing feed flowrate, flotation time, and conditioning time that may affect the floc-flotation performance of Jameson cells. Additional parameters, such as collector dosage, flocculant dosage, pH, and frother dosage, which may also be crucial for this procedure, have been also …

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses …
