Elution column filters (1 reply)

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 column, which very often pushes us to stop the elution. We installed a kason sieve (0.25mm) to the feed of acid wash column but the problem persists we have to shut down to unclog the filters. Do you have a solution for me?

Wash the carbon before elution tower or recirculate elution circuit solution clean screens then start strip.
