Abstract


GALLIUM IN A COPPEROREDEPOSIT OF THE FORE-SUDETIC MONOCLINE

Summary

Chemical analyses of about 320 samples from a deposit of copper ore in the Fore-Sudetic Monocline were used as a basis for determining, by means of mathematical statistics, Ga and Al2O3 concentrations in three different lithological series: sandy, shaly, and carbonate. The relationship between the contents of Ga and Al2O3 has also been examined.

Following classification standards introduced by J. P. Guilford (1964), the authors find that the Gal Ga/Al2O3 correlation is weak in the sandy series (relationship almost nonexistent), moderate in the shaly series (essential interrelationship), and low in the carbonate series (small but distinct interrelationship).

The dispersion of gallium in clayey minerals investigated here is such that in the present stage of technology, this metal cannot be obtained in the course of copper ore processing, and thus remains one of the waste materials. The generally high proportion of Ga to Al in the series investigated here seems to indicate that during the sedimentation of these series, terrigenous material was transported from the same source.
