Grinding Balls & Rods
The subject of grinding media (grinding balls & grinding rods) is still controversial. The following information is general and based upon facts gathered from many operations. General statements can be made and are worthy of consideration when selecting grinding media. For the best results it has been found that the smallest diameter ball or rod […]
Silver Gold Recovery Flotation Process
The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being […]
Compare Flotation Machines Types
In the 1950s, the opinion was often expressed that the mechanically-agitated machine forms the best rougher and a pneumatic machine the best cleaner, the reason being that the former type has come to be regarded as one that yields a heavily-mineralized froth, which, though giving a good recovery of the minerals, is likely to be […]
Flotation Conditioning
Flotation Conditioning is often necessary as it is not sufficient merely to make the addition of the various reagents to the pulp and then to proceed with flotation. Intimate admixture is essential in order not only to bring about their even dissemination throughout the pulp but also to ensure that the millions of particles of […]
Surface Tension & Contact Angle Flotation Bubble
Surface-Energy of Liquids and Surface-Tension The attractive forces mutually exerted between the interior molecules of a liquid produce at its surface the energy effects known as its “ surface-tension Within the mass of the liquid, each molecule attracts and is attracted by its neighbours with a force as intense as it is limited in range […]

Ball Mills VS Chilean Mills Comparison
Bowl Classifiers
The bowl classifier incorporates a two-stage baffled-return separating action, and it consists of a straight classifier with the usual reciprocating rakes, upon which is superimposed at the lower end a shallow circular bowl with a revolving rake mechanism. The general construction of the Dorr Bowl Classifier is shown in Fig. 20. The feed enters at […]
Slurry Pumps
When the slurry cannot be transferred from one machine to the next by gravity, one method of handling it is by means of a Wilfley slurry Pump, which is shown in Fig. 21. It is employed in most modern flotation plants for elevating and transferring all classes of material from coarse gritty slurry to fine […]
