This method of making soluble gold is known as leaching. In the process of leaching, a dilute form of sodium cyanide is added to the ore containing the gold. Since gold is soluble after the leaching process, it is free to move through the membrane, while the rest of the ore cannot pass through the membrane. Lime is added to sodium cyanide to ...
CO is adsorbed on the on-top configuration of the step sites in 1D arrangement. Low-coordinated sites are surface defects whose presence can transform a surface of inert or noble metal such as Au into an active catalyst. Starting with a well-ordered Au (111) surface we prepared by ion sputtering gold surfaces modified by pits, …
