Abstract

The Gibbs energy increments for minerals of Pb-jarosite group

Author(s): Oleg Viacheslavovich Eremin

The linear decomposition of standard Gibbs potentials (ÄfGº) values on chemical elements for three synthetic Pb-As, Pb-Cu, and Pb-Zn jarosites [6] have been calculated bymeans of linear programming problems. Comparison the errors of calculations ÄfGº with published data does not exceed on the average 1 %. The received equations have been used in calculations of Gibbs potentials for minerals with unknown thermodynamic properties.
