Because gold is already found in its 'native'o or unreacted state
carbon granules are then added to the solution, get the gold to pull from the cyanide solution and attaches to the carbon. The gold is then removed from the carbon by been washed in caustic cyanide solution. the carbon is them reused.
Carbon is not effective in extracting gold because gold does not readily react with carbon under normal conditions. Gold is a noble metal that has low reactivity, making it difficult to separate it from other metals using carbon as a reducing agent. Other methods, such as cyanidation or smelting, are more commonly used for extracting gold from ores.
The process that uses cyanide to extract gold is called cyanidation. In this process, gold ore is crushed and mixed with a cyanide solution to leach out the gold. The gold is then recovered from the solution by chemical precipitation or activated carbon adsorption.
To extract a metal using carbon, the metal ore is mixed with carbon and heated in a furnace. The carbon reacts with oxygen in the metal ore to form carbon dioxide gas, leaving behind the pure metal. This process is known as reduction and is commonly used to extract metals such as iron and copper.
Gold is formed independently from rocks so unlike iron or copper there is no 'ore' to extract it from. In general gold is acquired by finding nuggets in rocks. The gold is simply chipped off from the rock. It is extremly difficult if not impossible to extract the small traces of gold that can be found in many rocks and as far as i am aware no commercial technique for acccquiring such gold.

Carbon is commonly used to extract iron from its ore through a process called smelting. Carbon reacts with the oxygen present in the iron ore, reducing it to metallic iron.

Highly toxic cyanide is used to extract gold ore.

Dry blowers were used in the early goldfields to extract gold from dry soil without the need for water. It used air to separate the lighter material from the heavier gold particles, allowing miners to extract gold in areas where water was scarce.

Metals are extracted from ores. An ore is a rock that contains enough of a mineral (metal compound) for the metal to be extracted from it. Most metals are extracted from an ore by reduction with carbon or by electrolysis.
Gold is typically extracted from ores using a combination of techniques such as crushing, grinding, and chemical processes like cyanidation. The ore is pulverized to release the gold particles, which are then leached using cyanide to dissolve the gold into a solution. This solution is then processed to recover the gold through techniques such as carbon adsorption or precipitation.
- If you think to gold bromide this is used as catalyst in organic chemistry or for the detection of ketamine.- A bromine/bromide mixture was proposed to extract gold from minerals.
