Locked Cycle Testing -Flotation

Mar 17, 2017  Wikimedia. Flotation Locked Cycle Testing has been the favorite method for arriving at a metallurgical projection from laboratory flotation testing in the mining industry in the last decade, mostly because the final cycles of the test mimic a continuous circuit.. The difference is that, in a batch test, “the deportment of the intermediate streams to concentrate or tailings is unknown”, as ...

Medical Chemical Corporation: Para-site

A flotation procedure permits the separation of protozoan cysts, coccidian oocysts, microsporidian spores and certain helminth eggs and larvae through the use of a liquid with a high specific gravity. The parasitic elements are recovered in the surface film, and the debris remains in the bottom of the tube.
