Photos of gold ores, quartz, telluride gold ore and gold
These are free milling ores. By a free milling ore is meant one that does not require roasting before amalgamation will take place. Dry ore is the term often used. The second class of gold ores is auriferous copper ores. These are widely distributed throughout the United States and much of the chalcopyrite is gold bearing.

Extraction of gold using cyanide
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Processing Centers in Artisanal and Small scale Gold
this system is the fact that these centers barely grind the ore in order to liberate fine gold particles before processing. In all centers they use mercury to trap the gold from concentrates or from the whole ore. With this inefficient processing technique, the gold recovery is usually below 30% and in some rare cases can reach 50%.

How Is Gold Extracted From Gold Ore? Sciencing
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold

Gold Extraction and Recovery Processes
The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
