Flotation Process an overview ScienceDirect Topics

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Fecal Flotation VCA Animal Hospital

Fecal flotation is a routine veterinary test used to diagnose internal parasites or "worms." The test detects the eggs of mature parasites that live inside the body and pass their eggs to the outside by shedding them into the host's stool. Some of these parasites are worm-like, while others are tiny single-celled organisms called protozoa.

US20120087850A1 Process for Obtaining Apatite

The present invention, named Bunge/Fosfertil process, is applicable at different lithologies of phosphate ore with carbonated-silica matrix from igneous and sedimentary sources, i.e., consists of comminutioning the ore by crushing, homogenization, milling and disliming, prior to the apatite flotation. The dislimed and milled ore pulp with solids concentration above 40%, being initialy
