Abstract
This paper describes a particle agglomeration technique to improve the flow of leaching solution through heaps of low-grade gold-silver ores that contain clays. Bench-scale experiments and industrial practice have shown that the percolation rate of cyanide leaching solution is greatly enhanced by mixing the ore with portland cement as a binder, moistening the mixture, mechanically tumbling it to form agglomerates, and aging it before heap building and leaching. A slight modification of the technique allows its application to tailings containing precious metals, which cannot normally be treated by heap leaching because they are too fine.
