摘要：

A low-pressure, low-temperature chloride leach process called the Cashman process can be used to extract metals from arsenical flue dusts and residues and fix the arsenic in an environmentally stable form as ferric arsenate (scorodite). The process has been pilot tested in an integrated plant including continuous recycle; during the tests, several tonnes of flue dust were processed. Based on this pilot program, the process was deemed technically feasible, and its products are commercially salable. Residues from this pilot program were also subjected to a long-term stability test.
