Determination of Gold concentration in Recovery Water

Name: Gold in recovery water
Brand: CDR Galvan

The primary objective of testing gold concentration in recovery process waters is to optimize process efficiency and strictly control material costs. Given the high market value of gold, accurate quantification is essential to minimize financial losses, evaluate the performance of the recovery system, and conduct a precise cost-benefit analysis of the materials utilized.

Method

Test type: End Point.

Testing time: 1 minute.

Analysis sessions with multiple samples are possible up to a maximum of 16 tests for CDR GalvanLab^® and 3 tests for CDR GalvanLab^® Junior.

Step 1/10

Place the test tubes containing reagent R1 in one of the incubation cells and let them warm for at least 5 minutes.

Step 2/10

Collect 200 µL of sample with a pipette. Use a new tip for each test to prevent contamination from previous samples.

Step 3/10

Carefully clean the outside of the pipette tip with blotting paper, avoiding contact between the extremity of the tip and the paper.

Step 4/10

Place the sample in the cuvette. Keeping the tip immersed in reagent, press and release the piston of the pipette several times.

Step 5/10

Gently shake the cuvette 2-3 times.

Step 6/10

Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading that will last approximately 1 minute.

Step 7/10

Collect 10 µL of R2 with the pipette.

Step 8/10

Add 10 µL of R2 to the cuvette without touching the tip in the liquid. In case of contamination, replace the tip.

Step 9/10

Gently shake the cuvette 2-3 times.

Step 10/10

Place the cuvette in the cell marked with the blue light and press READ to perform the photometric reading that will last approximately 2 minutes.

Principle of the test

Gold content is determined by its reaction with a chromogen that develops a coloration, the optical intensity of which is proportional to the concentration of Au in the analyzed sample.
