Oregon has a richgoldmining history, and there is still plenty ofgoldwaiting to be found. Mostgoldprospecting in Oregon is done in the southwest and northeast parts of the state, where extensivegolddiscoveries have been made. Suction dredging, sluicing, and metal detecting are all good ways to recovergoldnuggets in Oregon.
Pneumatic (air-driven) rock drills speeded up drilling and further reduced the number of men needed underground. A process known as "chlorination" allowed better recovery ofgoldfromore. Eventually, mostorewas shipped to a smelter in San Pablo, which had the most efficient way ofseparatingout thegold.
