How the Gold Business Operates CNBC

01, 2011 · Gold mines produce rough gold, called a dore bar. These bars are typically about 80 percent pure gold. The gold is then sent to a refinery, where it is refined into gold of different forms and purity.

Day 51, Procedures to obtain gold: Vat Leaching Process Rio

Jul 29, 2013 · The ore is prepared for the vat either as a finely crushed or a coarsely ground and deslimed material. It is put into a container, the vat, which has a partial filter floor. Cyanide solution can be injected through the filter section of the floor or added to the top of the ore charge.

Gold Mining and Processing: Everything you Need to Know

Placer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies. The process begins when geologists take ore samples to determine the best places for companies to mine. Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, its mined with openpit mining techniques. Gold thats located farther below the surface is

Gold mining takes place in countries such as South Africa, Australia, the United States, Canada, China and Pakistan. One of the largest gold mines known worldwide is the Aurora Gold Mine located in Guyana, Africa. As of the year 2013, the Aurora Gold Mine has an estimated reserve of 6.54 million ounces.

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 2770 metric tons. With continued advancements in mining technology, this growth trend is likely to continue.[photo via]
