Ore Pretreatment or Beneficiation. A process step that may precede conventional agitation leaching and possible heap leaching is ore pretreatment or “beneficiation” in order to reduce the quantity of ore that will require chemical treatment. Beneficiation involves separating some of the host rock from the uranium-bearing mineral.

Heap Leaching: A Growing Technology in Beneficiation

The heap leaching technology has seen substantial growth over the past few decades becoming a key process in mining; NAUE a group specializing in geosynthetic liners assesses that over 30% of copper and gold produced each year is beneficiated via heap leaching up from only about 3% decades earlier.

Agglomeration technique improves heap leaching process ...

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 percolates through the heap.
