Standard Classification System WCIRB California

The primary purpose of the classification system is to facilitate the accurate collection of data so that the cost of workers' compensation insurance can be distributed as equitably as possible. To do that, the classification system is designed to divide payroll and loss data into groups in order to match the premium that you pay to the average potential risk of injury.

With specific reference to concentrate leaching, another key factor that possibly influenced the trends observed was the competing interaction of residual base metals with cyanide. Given that cyanide forms exceptionally stable complexes with Cu, Ni and Fe ( Smith and Martell, 1976 ), it is postulated that a high concentration of free thiocyanate was available for Pt and Pd extraction.
