Preliminary Construction of a Photo-Electric Cell Concentrator

The separation of the valuable portion from the waste portion of an ore is an individual problem for every ore. However, the various methods for accomplishing this end, more or less classify themselves by the physical properties of the constituents of the ore. Most of the properties of minerals have been utilized in some way or other to affect the separation of the valuable from the invaluable parts. Practically nothing has been done so far with color and luster to attain this purpose. It is believed that the photo—electric cell could also be used in concentrating a certain class of ores which are not well suited to other methods.
