The solution strips away the gold and is collected in a pond, then run through an electro-chemical process to extract the gold. This method of producing gold is cost effective but enormously wasteful: 99.99 percent of the heap becomes waste. Gold mining areas are frequently studded with these immense, toxic piles.
Tailings left in processing centres are leached with cyanide. Often, cyanidation is conducted in percolation vats as witnessed in Brazil, China, Colombia, Ecuador, Indonesia, Mozambique, Nicaragua, Peru, Tanzania and Zimbabwe (Fig. 2).Without proper aeration, the cyanidation process can last up to 50 days, and gold recovery can be as low as 50%.
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.
Searching for gold is a complex, scientific and time-intensive process. With odds of only one in 3,000 discoveries leading to mine development, and only 10 percent of the world's gold deposits containing enough gold to mine, exploration can be wearisome and expensive.
