The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to …

Diamond Processing Flow Chart of Beneficiation. Diamond Processing Flow Chart #3 This flowsheet illustrates a more complex diamond recovery method developed in recent years. With variations it can be used to process 100 to 500 tons per hour of Kimberlite ore and is also arranged to handle weathered or soft ores.
The mercury process has been used since the 1970s in many developing countries. In Latin America, for example, over 1 million people are directly involved in artisanal gold mining, recovering between 115 – 190 tons/year of gold, while releasing more than 200 tons/year of mercury into the environment (Veiga, 1997).
GPM own and operate the Zod Gold Mine and Ararat Processing Plant in Armenia to produce gold and silver bullion. In order to expand, GPM needed to treat the underlying sulphide material at the Zod mine which achieved around 20 to 30% gold recovery through their existing conventional CIL flowsheet. In 2010, GPM approved a refurbishment project …

Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks. In some jurisdictions, mercury use may be illegal or restricted in certain ways. The Minamata …
