How Does a Raw Mill Work in a Cement Industry

The operation of the cement raw mill is a critical step in cement production. By grinding the raw materials into a fine powder, these powders can be more easily mixed with other cement ingredients and burn more evenly during the cement clinker process. Therefore, the efficient operation of the cement raw mill directly impacts the production …

Gold and Silver Leaching by Cyanidation

Increase in cost of crushing and grinding is due to finer ball mill feed and regrinding flotation concentrate before cyaniding to 64%—10 microns. To supplement these figures it should be considered that where metallurgically possible, lower cost per ton will be produced from a combination circuit. However this should not be accepted blindly ...

The Importance of pH in Flotation

To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.

Gold Flotation

Flotation of Cyanide Residues. Flotation is used to recover residual gold-bearing sulphides and tellurides. The Lake Shore mill retreatment plant is an interesting example of this technique. The problem here was, of course, to overcome by chemical' treatment the depressing action of the alkaline cyanide circuit on the sulphides.
