Froth flotation process - Australia Innovates -

The froth flotation process for separating mineral ores was so much more efficient than previous methods it was soon adopted at metal mines worldwide. It greatly extended the life of the Broken Hill mines, making it, in economic terms, the most important Australian innovation of the early 20th century.

reported to be of critical importance for the direct flotation process. Intense conditioning can reduce reagent cost as much as 50%. Prolonged conditioning was also found beneficial to the direct flotation route but was not economically justified[4]. The adsorption of fatty acids on hematite plays a key role in the direct flotation route.

Mineral Flotation SpringerLink

Abstract. In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

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.
