HF as a gold recovery chemicals: Full name of HF is hydrofluoric acid. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water. Its Other names are fluorhydric acid and Hydronium fluoride.
chemical for recovering gold from ore
Leaching dissolves the gold out of the ore using a stone solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

Recovery (metallurgy) Wikipedia
Recovery is a process by which deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations, are introduced by stone deformation of the material and act to increase the yield strength of a material. Since recovery reduces the dislocation density the process is normally accompanied by a reduction in
