Benefits of Agglomeration in an SX-EW Process for Copper

Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered. For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator.

Heap leaching Wikipedia

Nickel ores. The method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores (as high as 1,000 kg of acid per tonne of ore,
