The classifiers for gold prospecting and gem hunting come in several shapes and sizes. We have the typical 14" classifier that is used atop a 5-gallon bucket. These are very useful out in the field where a couple people can shovel gold bearing material through the sifter at a time and fill several buckets within just a few hours' time.
The Dorr Company had been losing money because of faulty classification of gold ore and Dorr's solution was to invent a reciprocating rake classifier to replace inadequate classifying cones. It was accepted virtually immediately and subsequently marketed to other western mills.

In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps. It is relatively ...
Placer deposit is a significant source of gold, placer mining was the main method used in the early years of many gold rushes, like the California gold rush.

Gold ore crushed to the consistency of sand came from the ball mill and was mixed with water to produce slurry. Larger grains were separated in a Dorr classifier. The Dorr classifier was a trough like device with mechanical racks.
Gold Fever. On January 24, 1848, a thin piece of metal the size and thickness of a corn flake altered the history of California and, by extension, the history of the United States.
