Summary
The effect of hydrostatic pressure on the activity of Thiobacillus ferrooxidans grown on chalcopyrite concentrate has been investigated. It was found that bacterial activity, measured by conventional respirometry, was little affected by subjecting these microorganisms to a pressure of 100 lbs/in2 (690 kPa). The total cooper concentration was as high as 18 g/l in 28 days of leaching at atmospheric pressure.
