UNC operated the site as a uranium mill facility from 1977 to 1982. The mill, designed to process 4,000 tons of ore per day, extracted uranium using conventional crushing, grinding, and acid-leach solvent extraction methods. Uranium ore processed at the site came from the Northeast Church Rock and the Old Church Rock mines.

Uranium is extracted from ore by hydro-metallurgical process. After three stages of crushing, and two stages of wet grinding, the slurry thus obtained is pumped to leaching pachucas for dissolution of Uranium. The leached slurry is filtered to obtain liquor containing uranium which is purified and concentrated by ion exchange method.

Acid leaching has been used in the uranium milling industry since the mid-forties and has accounted for a majority of the production since that time. It is preferred over carbonate leaching because of its greater efficiency in recovering uranium. Consequently much research has been done on the factors which influence the kinetics of the oxidation of uranium, as well …

The sizes of crushing and grinding plants must be matched to the type of ore (hardness, size of ROM ore, clay content, etc.) and the throughput of the processing plant. The purpose of crushing and grinding is to liberate or at least expose the surfaces of uranium minerals to allow the next stage of extraction.
