Kemix - Carbon Adsorption

In a CIP operation the majority of the leachable gold has been leached prior to the first carbon adsorption stage. The gold adsorption is carried out in specifically designed tanks that are situated after the leaching tanks in the overall process flow. The adsorption tanks are typically a quarter to a tenth of the size of the leach tanks.

The diagram below shows a simple UV-visible absorption spectrum for buta-1,3-diene - a molecule we will talk more about later. Absorbance (on the vertical axis) is just a measure of the amount of light absorbed. The higher the value, the more of a particular wavelength is being absorbed. You will see that absorption peaks at a value of 217 nm.
