Standard cyanidation test conditions
Webb1.3 Various test solutions can be used at temperatures less than 100 °C. While the durability of the glass can be impacted by dissolving species from the glass, and thus the test can be conducted in dilute conditions or concentrated condition to determine the impact of such species, care must be taken to avoid, acknowledge, or account for the … Webbstage of these Hunt tests was slower than straight cyanidation and it became faster after six hours. No significant reduction was observed on the dissolution of copper. In the straight cyanidation with 350 ppm NaCN, 560 ppm Cu was dissolved whereas, in these Hunt tests, the dissolved copper ranged from 439 to 818 ppm. 0 10 20 30 40 50 60 70 80 …
