5. Definition Dilution refers to the waste material that is not separated from the ore during the operation and is mined with ore. This waste material is mixed with ore and sent to the processing plant (Jara, 2006; Sinclair, 2002). Dilution is the result of mixing non-ore grade material with ore-grade material during production, generally leading to an increase in tonnage …
