Flotation Machine - an overview ScienceDirect Topics

Industrial flotation machines can be divided into four classes: (1) mechanical, (2) pneumatic, (3) froth separation, and (4) column. The mechanical machine is clearly the most common type of flotation machine in industrial use today, followed by the rapid growth of the column machine. Mechanical machines consist of a mechanically driven impeller, which disperses air into the agitated pulp. In ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Handbook of Flotation Reagents ScienceDirect

The volume of froth generated in the flotation machine under standard operating conditions is often referred to as froth power. The froth power is influenced by the type of collector and frother used. Acidic frothers perform well only in acid pH. Typical examples of these reagents are phenols and alkyl-lauryl sulfonates. Basic frothers are represented by pyridine and homologs, recovered as by ...

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, mass-pull (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 ...
