Certain minerals, however, such as sylvite, carnallite, langbeinite, and polyhalite are found in ancientlake and sea beds and form rather extensive deposits from which potassium and its salts can readily be obtained. Potash is mined in Germany, New Mexico, California, Utah, and elsewhere. Large deposits of potash, found at a depth of some 3000 ft in Saskatchewan, promise to be important in coming years. 

For most of the decade prior to 1965, the United States was the world s largest single producer of potash. More than 90% of this production came from mines in New Mexico. As the grades of these deposits lowered and production costs rose, expanding production in Saskatchewan, Canada,... 

The lignite deposits of North Dakota and Montana extend into Canada as far as Saskatchewan. Canadian deposits are also located in Alberta, Yukon, the Northwest Territories, Ontario, and Manitoba. Production by open-cast mining, ca3.5 x 10 t in 1975, was 10.8 x 10 t in 1989.

Unconformity-Related Deposits. Deposits of the unconformity-related type occur spatially close to significant unconformities. These deposits usually developed during the period about 1800—800 million years ago in intracratonic basins. Deposits also developed during Phanerozoic time. Examples of unconformity-related deposits include the ore bodies at Cluff Lake, Key Lake, and Rabbit Lake in northern Saskatchewan, Canada, and those in the Alligator Rivers area in northern AustraHa (12). 

Heavy-Media Separation. Heavy-media separation, depicted in Eigure 3, can only be used for relatively rich sylvinite ores that consist of large crystals of KCl and NaCl, such as those mined in Saskatchewan (6,20). Crystals of the two salts in the Saskatchewan deposits are 6—9 mm in diameter. Mine ore that is cmshed sufficiently to pass through 6—9-mm screens in this size range results in a mixture consisting of discrete grains of each salt.

Uranium is found in most rock, in a concentration of two to four parts per million (ppm). Substantially greater average concentrations can be found in mineral deposits, as high as 10,000 ppm, or 10 percent. Most uranium deposits suitable for mining, however, contain an average of less than 1 percent uranium. Uranium is a metal, and thus its acquisition is not unlike the mining of any other metallic ore. Although uranium is found nearly eveiywhere on the earth, Canada leads the world in uranium production, mostly due to its heavy financial investment m uranium exploration, and to a few sizable deposits in the Saskatchewan territoiy. Table 1 depicts the total world uranium production in 1997.

Chen et al. [24] provide a good review of Al techniques used for modeling environmental systems. Pongracz et al. [25] presents the application of a fuzzy-rule based modeling technique to predict regional drought. Artificial neural networks model have been applied for mountainous water-resources management in Cyprus [26] and to forecast raw-water quality parameters for the North Saskatchewan River [27].
