gold leaching pilot plant

THIOUREA LEACHING OF GOLD IN A CONTINUOUS PILOT PLANT ...

1987-1-1 · Sonora pyritic gold concentrate was continuously leached in a two-stage thiourea pilot plant which was operated at 750 g/hr. The pilot plant incorporated automatic solution potential control and solution recycles. Gold recovery by cementation onto atomized aluminum was done on a batch basis.

Gold refining by solvent extraction—the Minataur™ Process

2009-8-26 · The leaching operation was conducted on a batch basis. The feed material was leached in 6 M HCl, with chlorine contin-uously sparged into the leach reactor. After leaching, the solid residue was filtered from the gold-containing solution. A summary of the pilot-plant leaching results is shown in Table II. Because of its high gold content, the Peñoles feed
