Lead design and extraction. The profile of an ideal lead should be overall coneshaped with every transition in the lead the diameter should decrease slightly, making it easier to pull the lead from and through the scar. Active fixation mechanisms are therefore preferred to avoid the protruding flanges.

The Chemistry of the Extraction of Gold  SAIMM

The Chemistry of the Extraction of Gold SAIMM

Gold dissolves readily in aqueous chloride solution in the presence of an appropriate oxidizing agent (such as chlorine, nitric acid, or ferric ions) to form the tetrachloroauric ion. This ion can be isolated as a hydrated acid, such as H[AuCI413H20, by evaporation of the solution, or as a salt such as Na[AuCI41.
