How to Operate a Flotation Circuit - 911 Metallurgist

25/04/2016  A flotation machine needs deep froth in order to allow time for unwanted mineral to drain from the froth bubbles back into the pulp. Also, a high pulp level isn’t so important in a cleaner cell, because recovery isn’t what you’re after so much as grade of concentrate. Therefore, in a cleaner cell, a froth depth of at least 8 in. is required in most cases, and you have more leeway in adjusting the pulp level. That is why, in operating a cleaner,

Flotation Machine - an overview ScienceDirect Topics

To do this, a flotation machine must maintain the particles in suspension, generate and disperse air bubbles, promote bubble–particle collision, minimize bypass and dead spaces, minimize mechanical passage of particles to the froth, and have sufficient froth depth to allow nonhydrophobic (hydrophilic) particles to return to the suspension.

Flotation Machine - 911 Metallurgist

20/04/2016  A flotation machine must not only be able to circulate coarse material (encountered in practically every mill circuit) but also must re-circulate and retreat the difficult middling products. An alternate pulp flow is obtained from cell to cell by the side ports in the partitions. The ports are adjustable so that a portion of the pulp can pass from cell to cell through these ports and consequently bypass

22/06/2015  Below is a typical bank of flotation cells used in industrial practice. The procedure by which air is introduced into a mechanical machine falls into two broad categories: self-aerating, where the machine uses the depression created by the impeller to induce air, and supercharged, where air is generated from an external blower.

Installation, Operation Maintenance Manual

A DAF (Dissolved Air Flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. Once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. The treated wastewater then exits from near the bottom of the DAF.
