Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that has been proven to contain gold or silver and is then separated as a gold cyanide or silver cyanide solution from ground rock. To precipitate residual zinc and silver and gold metals, zinc is added.

The rocks that have gold in them are quartz, iron, magnetite, pyrite, and Lead. However, not all will contain gold. They only give you better chances of identifying gold-bearing grounds. Analyzing the rocks' surface, and using topographic maps and geological reports can be useful.

Where to find gold Gold is often found in underground veins of quartz and, less frequently, in other minerals such as pyrite, granite and mica slate. The veins can be anything from half an inch to several feet wide. 80% of the gold that's produced today is mined from such sources (the rest is 'alluvial' gold – see below).

This type of gold is highly desired in the mineral collecting community. Gold/Quartz specimens are in a completely different league of their own. Remember the specific gravity of quartz is 2.65 times heavier than water, whereas pure gold is 19.3 times heavier than water! View more 1.03 Gram Winnemucca Nevada Gold Nugget $80.00

These rocks can be found in mines in countries such as Botswana, South Africa, Russia, Angola, Australia, and Canada. 2. Lamproite Lamproites are ultrapotassic mantles derived from subvolcanic and volcanic rocks. Though the stones are widespread geographically, they're insignificant in volume. The breccia tuff erodes quickly, leading to diamonds.

A typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenic-bearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.

To identify your rock, first take note of its physical properties like color, luster, banding, layering, and grain size. Next, test for hardness and weight by running simple tests. Finally, compare the properties of your rock to those of known rock types while looking for other identifying characteristics. Identifying and classifying rocks can ...
