Opaque, white pollucite may be homogeneous, but tends to contain inclusions. Altered, white pollucite is invariably 328 Journal of African Earth Sciences The compositional evolution of pollucite from African granitic pegmatites heterogeneous and strongly re-equilibrated and tends to contain many inclusions.
Alternatively, caesium metal may be obtained from the purified compounds derived from the ore. Mining and refining pollucite ore is a selective process and is conducted on a smaller scale than for most other metals. Therefore, the largest deposits of caesium are zone pegmatite ore bodies formed by this enrichment process.
Tanco Mine Hydrothermal Secondary Minerals Tanco Mine, Bernic Lake, Manitoba, Canada Richard Gunter M.Sc., P.Geo. 5493 Cedarcreek Drive, Chilliwack, British Columbia pamrichgshaw.ca The Tanco Mine was a major commercial producer of tantalum concentrate, ceramic-grade spodumene and cesium formate for oil-well drilling fluid.

Such CO 2 ... Quartz from the high grade pollucite zone has very variable low temperature decrepitation, sometimes with and sometimes without gas ...
This round of drilling confirmed the continuity of the pollucite mineralisation, significantly de-risking the project from an ore supply perspective. Pioneer recently completed a drilling program with its Joint Venture partner, TSXV-listed International Lithium Corp. at the Mavis Lake lithium project in the province of Ontario, Canada.

A major source of lithium, the mineral petalite rarely occurs in gem-quality crystal form. Although colorless, glassy crystals can make stunning faceted jewelry pieces, beautiful pale gray, white, yellow, and pink stones can also be found. Gem cutters occasionally cab massive pink material from Namibia.
