2017815&ensp·&enspGold Flotation I. INTRODUCTION Froth flotation is a widely used separating technique for the recovery of Cu and Au in porphyry coppergold ores. In these ores, chalcopyrite and gold are the main valuable mineral/metal phases, with pyrite being the key sulphide gangue mineral. However, in these ores gold is mostly associated with pyrite
1992616&ensp·&enspThis invention relates to the froth flotation of calcium borate minerals, particularly colemanite and ulexite minerals. Froth flotation is a commonly used process of separating desired mineral particles from unwanted mineral particles such as silica, silies and other similar materials, or of separating particles of one desired mineral from those of another desired mineral. A surface active
Flotation: Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.
20191117&ensp·&enspFroth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Edelmira D. Gálvez, Luis A. Cisternas, in Computer Aided Chemical Engineering, 2014. 1 Introduction. Flotation circuits are a common technology for the concentration of a broad range of minerals and wastewater treatments. Froth flotation is based on differences in the ability of air bubbles to adhere to specific mineral surfaces in a solid/liquid slurry.

2019119&ensp·&enspFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.History&ensp·&ensp

The flotation model developed by the AMIRA P9 Project, of which Outotec is a sponsor, is regarded by industry as the most suitable flotation model to use for circuit optimisation. This model incorporates ore floatability with flotation cell pulp and froth parameters, residence time, entrainment and water recovery to the concentrate.

Particles of a calcium borate mineral, such as colemanite or ulexite, are recovered from an ore by a froth flotation process using a dialkyl sulphosuccinate as collector. Suitable dialkyl sulphosuccinates include sodium or ammonium dinonyl sulphosuccinate, sodium or ammonium diisodecyl sulphosuccinate, and sodium or ammonium dilauryl sulphosuccinate.
