The effect of energy input on the flotation of a platinum

Aug 15, 2017· This suggests that higher energy inputs are generally beneficial for the flotation of platinum ores as these consist predominantly of finer particles and most industrial flotation applications operate with larger bubbles (1.0–2.0 mm), as observed in the flotation literature (Deglon, 2005).

Flotation | ore dressing | Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Flotation Technique for Fecal Parasite Concentration

This technique is predominantly used in parasitology laboratories. By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.. The most commonly used reagent is zinc sulphate.Operculated eggs as well as schistosoma and infertile Ascaris
