Experimental studies and pilot plant tests for acid

The pilot plant was built in the Gobi Desert. The six heaps operated well at heights from 1.4 to 4.1 m. Detailed investigations of the permeability, copper leaching rate, acid consumption and water evaporation showed that heaps of − 40 mm ore leached for 68 days produced a copper leaching rate of up to 85.8%.

Pilot plant for biohidrometallurgical production of copper

In the pilot plant, processes such as: microbiological leaching, pressures oxidation, chemical purification of solutions, solvent extraction and electrowining of copper were carried out.
