ISO 88583:2004(en), Hard coal ? Froth flotation testing

To facilitate the determination of how a particular coal will respond to froth flotation, a method of controlling the recovery of froth is used. This is done by inhibiting the process to a degree, determining the rate at which coal reacts and by progressively sampling the froth.

Ultimate Froth Flotation Performance Test ACARP

The C14068 UFT froth flotation test method is a very precise method with very limited operator interpretation. The International Standard ISO 88583 for froth flotation testing of hard coal was only trialled on the Hunter Valley (HV) sample and the results

In flotation processes, concentrate grade is the key production index but is difficult to be measured online. The mechanism models reflect the basic tendency of concentrate grade changes but cannot provide adequate prediction precision. The datadriven models based on froth image features provide accurate prediction within wellsampled space but rely heavily on sample data with less

Sampling from large flotation cells DIVA

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, masspull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a
