Zeolites: A Review of 1993 Activities

The zeolites review arrived too late for the June issue. The natural zeolite industry continues to grow even as some companies look for the exits. Production for 1993 was estimated at between 42 and 44 kt (46,000 and 48,000 st). That is between 7 and 9 kt (7700 and 9900 st) above 1992 production. GSA Resources, Saint Cloud Mining, Steelhead Specialty Minerals, Teague Minerals, UOP and Zeotech all reported continued growth last year. At the same time the East-West Minerals' Eastgate mordenite mine, and American Resources' Ash Meadows clinoptilolite operations both shut down their processing plants and are attempting to sell the mines and facilities. In addition, Tenneco Minerals continued its attempt to sell the Mud Hills clinoptilolite deposit. Unimin entered the natural zeolite industry through its acquisition of several properties of Aimcor. The properties included the Ben-Jel bentonite and Castle Creek clinoptilolite deposits and processing facilities near Caldwell, ID
