Processing gold involves transforming rock and ore into a metallic alloy of substantial purity known as doré typically containing between 6090% gold. During its life, a number of factors such as the price of gold or input costs will affect which areas of an ore body are deemed profitable (economic) to mine.

There are three basic steps in a gold mining operation: exploration, extraction, and processing. Exploration involves finding the area of interest, characterizing the ore body, and determining the type of processing required. This is done by collecting samples, analyzing the results, and planning a mining program to exploit the ore body.

The expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation. In the 20th and 21st centuries, most volume of mining was done by large corporations; however, the value of gold has led to millions of small, artisanal miners in many parts of the Global South .
