The calico silver-barite deposits near Barstow, California, are a potentially important resource. Exploration performed by two major mining companies outlined large tonnages of ore that assayed at 2 to 3 ounces of silver per ton and 7 to 15 percent barite. Laboratory beneficiation work was done by the Bureau of Mines on four samples to develop methods for recovering the silver andor barite.

Crushing process silver ore beneficiation begins with the milling of extracted ore in preparation for further activities to recover silver values.Milling operations are designed to produce uniform size particles by crushing, grinding, and wet or dry classification. Milling is a multistaged process and it can be divided into primary crushing, secondary crushing and fine crushing.

Abstract. Investigations are presented of methods for the physi cal beneficiation of low-grade and other uranium ores. The investlgations which have been in progress since September 1952 cover work done on a variety of natural ores, as well as a certain amount of basic research on mixtures of synthetic or high-grade natural uranium minerais with various gangues.
