Gold Minerals In nature, gold most often occurs in its native state (that is, as a metal), though usually alloyed with silver. Native gold contains usually eight to ten percent silver, but often much more — alloys with a silver content over 20% are called electrum [1].

A number of auxiliary materials handling operations are also considered a branch of mineral processing such as storage (as in bin design), conveying, sampling, weighing, slurry transport, and pneumatic transport. The efficiency and efficacy of many processing techniques are influenced by upstream activities such as mining method and blending.
Jan 23, 2012· Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (off-site)
Chemical composition of gold particles and associations with other minerals affect gold recovery by flotation. In general, gold-pyrite or gold-copper minerals associations have no problems and gold can be recovered without major problem. The lack of good liberation is a problem and the comminution circuit is the key element.

Oct 30, 2019· To complicate matters further, these ore bodies are often refractory, where the gold is locked within sulphide minerals; or double refractory, in which gold is locked within sulphide minerals and preg-robbing due to the presence of organic carbon. These must be pretreated ahead of leaching.
Gold is one of the first minerals used by prehistoric cultures. The Latin name for this mineral was "aurum" and Jöns Jakob Berzelius used Au to represent the element when he established the current system of chemical symbols.
