Flotation - Mineral Processing & Metallurgy

Jan 11, 2016 · The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores.

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.
