flotation separation A concentration process where by finely ground ore is dispersed in water containing a flotation reagent which causes selected minerals to become hydrophobic. Aeration and agitation of the suspension allows hydrophobic particles to float while unaffected minerals sink. The floating particles are skimmed off or overflow the flotation cell.

It's Scots, laddie. The term "floatation" is widely used in Scotland, as opposed to the UK in general, being much more common than "flotation". While this can be confirmed by searching the web for floatation and reading Scottish related entries, a good idea of what will be found is obtained by searching the web for. "floatation" related_term.

In order to determine the contribution of the flash flotation circuit to the overall plant performance of the Kanowna Belle concentrator, two survey campaigns both with and without the flash circuit in operation have been conducted on two distinctly different ore types: a very high grade ore, and a very low grade ore of higher hardness. ...

Coarse particles require distinctly different conditions to their fine and intermediate counterparts for successful flotation and recovery to the concentrate launder. These range from simple operational requirements such as shallow froth depth, reduced impeller speed and higher collector dosage to those that must be optimised specifically for the coarser size fractions such as air …

1. Introduction. The minerals concentration is the operation about the tenor or concentration rise (in percentage) of an ore or mineral rises, through the use of solid-solid separation equipment which allows the segregation of two or more mineralogical species, generating an enrichment of the aforementioned mineral in the stream [].The flash flotation is a method that uses the …

Both "flotation" and "floatation" are acceptable spellings for the same term, and both are used to describe the same process. "Floatation" has the older pedigree between the two words; its first confirmed use was in 1806. "Flotation" wasn't used until the 1850s, and it appears to be a derivative.

1. A grinding device suitable for operating inside a flotation cell, the grinding device comprising: a collection zone in which particles are collected through a settling process; a grinding zone in which particles are milled to undergo a size reduction process; and a pumping zone from which milled particles are recycled into a flotation cell.

Messages. 373. Oct 3, 2020. #2. It all depends what form your carbon is in and what ore components carry the gold. If the ore has to be very finely milled to release the carbon then you will probably have to revert to kerosine blinding of the carbon rather than flotation. If the ore carries the gold in sulfides then fine milling makes clean and ...
