Intensive Cyanidation Leach Optimisation - Hydrometallurgy: Leaching in ...

In an ILR the washing is very thorough due to the positive mixing of the solids; in an Acacia there is no positive mixing so you are relying on getting an even distribution of solution through the fixed solids bed. Comparing wash and preg solution grades and volumes will identify if this is happening.
