METHOD FOR BORE-HOLE LEACHING OF HIGH-CLAYLY ORES Russian patent published in 1997 - IPC

Abstract RU 2092688 C1

FIELD: geological technology. SUBSTANCE: this can be used for lixiviation of gold from high-clayly ores. Method implies opening of ore beds, creation of technological bore-holes, establishing circulation of solutions, delivery and withdrawal of productive solutions. At leaching of multiple-bed deposits with insufficiently impregnated ore beds, injection bore-holes are drilled through entire depth of deposit, and withdrawal bore-holes are drilled only down to foot of insufficiently impregnated bed. EFFECT: high efficiency. 2 cl, 1 dwg
