Repoussé or repoussage refer to a metalworking technique in which a malleable metal is shaped by hammering from the reverse side to create a design in low relief. Chasing, chased work, or embossing refer to a similar technique, in which the piece is hammered on the front side, sinking the metal. The two techniques are often used in conjunction. Many metals can be used for chasing and repoussé work,

DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.
Silver & Cobalt Processing by Gravity and Flotation. The treatment of complex silver cobalt ores occurring with antimony and arsenic require special metallurgical processing to produce concentrates most advantageous for smelting. Gravity concentration is used to initially recover a high percentage of the native silver and cobalt.
Cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal close packed crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is face centred cubic. The metal has 12 radioactive isotopes, none of which occurs naturally.

Controlled oxidation of gold containing chromium or cobalt (e.g. 75% gold, 25% cobalt). A range of colors from brown to black can be achieved on copper rich alloys by treatment with potassium sulfide. Cobalt containing alloys, e.g. 75% gold with 25% cobalt, form a black oxide layer with heat treatment at 700950 °C.
