More than 90 percent of the world's gold has been produced following the rushes of the mid- to late 1800s [source: World Gold Council]. The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between

produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to 95-99% by grinding to fairly fine particle size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation of

· They then tunneled horizontally to follow the richest ground. This approach is called drift mining (the horizontal tunnel is the drift). These shafts and tunnels were typically dug in winter so that frozen ground would not melt and collapse on the miners. Even so, the practice was arduous and dangerous. In the spring and summer, a defrosting pile of gold-rich gravel called
The Gramalote mining project proposes to develop an open-pit gold mine. The ore deposit covers an area of km2 within the central mountain range in the area.

The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots. MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual

They weren't all that uncommon during the early mining days, but the gold deposits had to be the right type to warrant this type of mining. This type of mining involves tunneling horizontally into a hillside, but it is very different from a standard hard rock mine that is following a vein. In contrast, a drift mine for gold is working a layer of auriferous gravel in an alluvial deposit. In

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
It was the most basic method to obtain placer gold. The basic procedure was to place some gold-bearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the side. If all went well, the heavier gold nuggets or gold dust would settle to the bottom of the pan. Gold
