ABSTRACT

The purpose of this paper is to describe a new method of leaching refractory ore with
complex leaching solution consists of various chemical substances on the basis of liquid
culture heterotrophic bacteria Pseudomonas aureofaciens. The usage of this complex
solution was resulted in considerable noble metals solution increase with a little time of
leaching. Experiments were planed with the method of mathematic planning. Quantumchemical
counts have shown stability of metal complexes have been created in this
solution system.

Keywords: noble metals, complex solution, mathematic planning.
