Siberian Sluice
The Siberian Sluice and the apparatus at Voltchanka, which may be taken as a type, consists of a head sluice and three secondary sluices, which are placed at right angles to the head sluice, and which leave it at different points and converge to a common centre, where the tailings are discharged. The head sluice […]
How Does a Gold Dredge Work
To understand How Does a Gold Dredge Work, we may want to start by looking at California or Alaska. Gold dredging in now practised on the rivers of California, has is now superseded river mining. In river mining, an entire river was frequently deflected from its course so as to lay bare a section of its bed. […]
Concentrate Dewatering & Thickening
The concentrate from the flotation section usually contains only 20 to 30% of solids as it leaves the cleaning machine and must be dewatered before being sent to the next department. The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate […]
Comminution Theory & Process Equipment
This page is devoted to the subject “From the Comminution Theory to Practice by selection of the correct Process Equipment” by taking you step by step through some of the variables encountered in the specific part of Comminution called grinding and how each of these affect your operations. Should it be possible to reduce all of these variables to […]

This crusher is the finest of our lines of jaw crushers which we offer. Others include: Superior, Type “B” Blake, Fine-Reduction and Dodge — sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in a straight line between jaws — without grinding or rubbing surfaces. LOWER JAW CRUSHING COSTS As […]
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 […]

MIBC Frother Pump
I once had to conduct an MIBC frother test to confirm if it could give me better flotation results than the glycol frother my client was using. The technical/metallurgical problem we had in the plant was best described in the video below as well as a poor concentrate grade. My “challenge” was that since MIBC […]
Infrasizer
Because of the extremely fine grinding necessary to liberate the gold values, closer control than that obtained by screens was found to be necessary, and Professor Haultain’s “Infrasizer” was successfully adopted as a plant-control and research device. A brief description of the instrument is found in “Fine Grinding Investigations at Lake Shore Mines” {Trans. 42, […]
