How Gold Is Mined | Gold Mining Process | World Gold Council
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

Extracting Gold | HowStuffWorks
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Overall, gold recovery using heap leaching generally ranges from about 50 to 90 percent, although this percentage depends on many variables (Kappes, 2002; Marsden and House, 2006). Figure 1 is a simplified flow diagram of the gold heap-leach process.

Cyanide Process
Cyanide process which is also known as the Macarthur-forest process is widely used in extracting gold or silver from the ores by dissolving them in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by Scottish chemists named Robert W. Forrest, John S. MacArthur, and William Forrest.

The main disadvantage is that gold recovery is generally lower than that achieved by grinding to a finer size and leaching in stirred tanks. In addition, the rate of leaching is slow and recoverable gold can be held up in the heap for months, which impacts cash flow. There can also be longer term environmental

Gold Extraction & Recovery Processes
Gold recovery with sluices can vary depending on several factors. Fine gold losses can be minimized by cleaning up more frequently, reducing the speed of the slurry flow to around 0.50 to 0.80 m/s., and decreasing the feed size by performing a previous screening.
