ESTIMATION OF FACTORS OF THE MECHANISM OF FORMATION OF DRAINAGE WATERS OF VARIOUS TECHNOLOGICAL TYPES OF ORES OF COPPER SANDSTONE DEPOSITS BY THERMODYNAMIC MODELING OF THE «WATER-ROCK-GAS» SYSTEM
SUMMARY: In the paper the physical and chemical conditions are considered for the formation of the chemical com-position of waters draining rocks and ores of the copper sandstone deposit, with more attention to the main factors of their acidification. Thermodynamic simulation of water-rock-gas system shows that pyrite percentage is key factor for aggressive medium formation at pyrite content more than 1% and lgf O 2 >-20. Relative water filtration speed expressed by mass of rock (R) to mass of Water (W) decreases aqueous pH at R/W>0.1.
