List of countries by gold production - Wikipedia

This is a list of countries by gold production in 2018.. Until 2006 South Africa was the world's largest gold producer. In 2007 increasing production from other countries and declining production from South Africa meant that China became the largest producer, although no country has approached the scale of South Africa's period of peak production during the late 1960s and early 1970s.

Gold Extraction & Recovery Processes

The agglomerates are recycled in order to contact fresh ores and increase the gold content. In this way, the process is a development of spherical agglomeration for recovering fine particles by using coal-oil agglomerates. The agglomerates are burned in order to produce a product with high gold content or can be smelted for producing metallic gold.
