Agglomeration Technique Improves Heap Leaching Process

Jul 05, 2018 Copper heap leaching with agglomeration. Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components Crushed ore is stacked on a leaching pad and irrigated with the leaching agent. The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it ...

Sulfuric Acid Injection In Copper Heap Leaching Lewa

The leaching reagent dilute sulfuric acid is sprayed through sprinklers on top of the heap pile and allowed to trickle down through the heap, where it dissolves the copper from the ore. The resulting solution of sulfuric acid and copper sulfate is collected in a small pool. Copper concentration is around 65. Next step is solvent extraction.

Heap Leaching A Stack Of Gold Miningfeeds

Apr 25, 2018 The methodology selected is a function of the mineralogy of the ore. If the gold is associated with oxides, for example, it can be amenable to heap leaching. The grade also plays a key role. Heap leaching is used for low-grade oxides, while high-grade ore with or without oxides is better suited to CIP or CIL methods, says Bundo.
