Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earths crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions
Cyanide is a naturally occurring chemical that is found in low concentrations throughout nature including in fruits, nuts, plants, and insects. It has been used by the mining industry to separate gold and silver particles from ore for over 120 years. With proper management, cyanide can be used safely and without harming the environment

2018 9 5ensp;0183;ensp;Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon in leach. This is a gold extraction process called cyanidation where carbon is
2018 8 22ensp;0183;ensp;Gold cyanidation (also known as the cyanide process or the MacArthur Forrest process) is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex.It is the most commonly used leaching process for gold extraction..

Before the cyanide process was introduced, although the assay value of the quartz at Martha Mine was reasonably high, gold recoveries were low.
Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates.

Minera Seafield, now Miraflores Compania Minera SAS (MCM) owns 100% of the Quinchia Gold Project (Quinchia Portfolio) in Colombia where a NI 43 101 mineral resource of 2.8 million ounces of gold
Free gold is that which can be easily liberated and is unbound to other minerals. Free gold can be rapidly recovered in high amounts using gravity concentration methods.
THE BASIC PROCESSES OF GOLD RECOVERY INTRODUCTION. Man has held a fascination with recovering and acquiring gold almost since the beginning of time.
Detour Gold Corporation (TSX DGC) (quot;Detour Goldquot; or the quot;Companyquot;) is pleased to report positive results from the feasibility study for a proposed open pit mine at its 100% owned Detour Lake gold project in northeastern Ontario.
