Crushed ore agglomeration and its control for heap leach …
For example, the copper ore agglomeration is typically conducted in a drum agglomerator with low additions (15–25 kg) of sulfuric acid per ton of ore and about 60–100 kg of water. Gold heap leaching operations practice the USBM's procedure, which includes alkaline leaching following cement and dilute cyanide solution addition during the ...

Selective oil agglomeration of Agbaja iron ore | SpringerLink
Starting from a crude ore assaying 45.6% Fe, a fine-grained oolitic iron ore was concentrated by the oil agglomeration technique to 90% Fe recovery and 65% Fe assay. The ore required grinding to minus 5 μm to effect adequate liberation, and the technique yielded optimum results at pH 9. The roles of pH, collector, and bridging liquid concentrations on selectivity and …
