Donald Heiman

Factors which contribute to magnetostructural transition control have been demonstrated by study of the effects of Au incorporation on the magnetic and structural character of CsCl-structured equiatomic FeRh thin films. Sputtered films were capped with 2 nm of Au deposited at 873 K and at 323 K and subsequently characterized with magnetometry and synchrotron-based structural probes. Diffusion of Au into the FeRh film layer at 873 K is confirmed by a reduction in the Au capping layer thickness relative to the film capped at 323 K. The impact of Au diffusion on the FeRh magnetostructural character is noted by a …

Gold has been extracted from its ores since ancient times. The modern industry, however, was established about hundred years ago when the cyanidation process was invented in 1887. The process was applied successfully for a variety of ores and found wide-spread application in 1970’s for ores containing as low as 1 ppm gold. In the last decade new chemical beneficiation process have been developed to treat ores that are not directly amenable to cyanidation. These involve aqueous oxidation of sulfide minerals containing gold at high temperature and pressure in autoclaves lined with acid-resisting brick.
