Stamp Mill Animation
When stamp mills are used for dry crushing, double discharge mortars are provided (see Fig. 50), and the screens are put low down, giving a small depth of discharge. These arrangements are necessitated by the difficulty of discharging the crushed ore from the mortar, the only means of doing this being the dashing of the […]

Estimation of Free Cyanide using Iodine and Potassium
The process of estimating free cyanide depends upon the fact that when a solution of iodine in potassium iodide is added to a solution of a simple cyanide, the reddish-brown color of the iodine solution disappears so long as the cyanide is in excess, since the reaction results in the formation of an iodide of […]
Mineralizers
Combining mineralizers and a group of minerals which it has been impossible to synthesize by the open fusion method, as there is contained in their molecule small amounts of volatile compounds as fluorine, water as hydroxyl, or chlorine; or again the fusion at the point or temperature of crystallization is so viscous as to prevent […]

History of Flotation Patents
This is the part of the subject of which we have heard the most; indeed, until recently the literature of the flotation process was closely identified with the records of patent litigation. That is why the scientific principles are as yet so little understood and the technology of the process has made such scanty progress. The aim […]
