Elution column filters
Hello ! In our gold processing plant we pratice the elution of pregnant carbon by the zadra process, We use two columns: one for acid washing and the other for elution, but the filters in the elution column are clogged very often (probably due to the presence of impurity coming in with the pregnant carbon from CIL tank), which means Leads to very high pressure in the …

Elution Efficiency
AARL elution relies on low hardness (or ionic strength) of hot water used for elution. Demin water is not necessary, but normally some form of soft water with low ionic strength works well. Some mines make the mistake of using process water to cut costs. AARL elution is favoured by absence of Ca and Mg.
