1. Exploration EXPLORING FOR GOLD IS A COMPLEX, SCIENTIFIC AND TIME-CONSUMING 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 labor-intensive, time consuming and expensive.
one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the non-metallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly
Under the pre-modern contracting system, miners called yamashi or kanako were paid according to the amount of mineral extracted from the ore and not on the basis of the volume of unrefined ore. 33 This system encouraged the development of a technology for dressing ores at the mine site, but the yamashi and kanako were not able to develop the technology for an integrated
Processing a gold ore with mercury has, historically, been useful in increasing the recovery rate of gold particles. This procedure may have been, as well, popular today if not for its dangerous effects on human health and the environment.

Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops. In both mining techniques, the mined ore must be removed from the mine and transported to a plant for processing and refining.
