Five factors are required for the formation of uranium deposits: a source, transporting medium, host, trap, and preservation. Locating and evaluating uranium deposits requires ail integration of methods and techniques to determine if the above factors are present. A typical exploration program consists of selection of a favorable area, field reconnaissance, land acquisition, and target definition and evaluation. Target definition and evaluation utilizes a combination of geologic mapping, geochemical surveying, geophysical surveying, and drilling and logging. Each overlaps the others to some degree.

Stringent environmental regulations, which have limited the use of sludge ponds, coupled with the economic incentive to clean more coal or to add fine coal cleaning additions to existing preparation plants have increased the use of static thickeners in preparation plants. The Lamella Gravity Settler, sometimes designated Lamella Thickener, is a shallow depth sedimentation device which has been applied in a variety of industrial process and wastewater control projects in place of the conventional raked thickeners. This paper presents the theory and design of the Lamella Thickener, as well as describing the operating results from several full scale installations in a variety of Appalachian preparation plants.

The orebodies are long bedding-plane lenses of chalcopyrite and sphalerite, associated with garnetite masses. Most of the orebodies are within a 50-ft thickness of Cambrian limestone; other Paleozoic limestones and dolomites are locally metamorphosed but only slightly mineralized. Pre-mineral faults are numerous, but shallow folds were the main ore-localizing structures.
