Additional information

Slimes and sludges, precious metal refining, is a solid, with a relative density of 2.03 at 22.5°C and a melting point temperature of greater than 450°C (>723K). As water solubility testing is not appropriate for complex metal and sparingly soluble metals and metal compounds, transformation dissolution testing has been conducted and the results are presented in IUCLID Section 5.6 and CSR Section 4.5.
