ancient mining techniques go well back into our history – well back into our . prehistory, in fact. as we progressed through the stone age, with more and . more sophisticated tools and weapons being designed and developed, so too, our need for more and better raw materials for these implements. stone and flint led to copper, then bronze, gold,
the gold rushes of the 1850s were a time of unparalleled social and economic development, when mining techniques leap frogged from the rudimentary to the sophisticated in a few short years. in 1851, as gold fever began to spread, the sight most commonly encountered by "new chums" eager to find their

gold mining was rough, physical work. where alluvial gold was very rich, it could be obtained with a shovel and pan. however, pans were used mainly for prospecting. simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth – the heavier gold collecting on matting on the cradle base.

unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. the word placer is thought to have come from catalan and spanish, meaning a shoal or sand bar. the word entered the american vocabulary during the 1848 california
gold mining techniques. the pictures linked below are from mrs. atkinson adams intro. to u.s. history class at logan high school. panning for gold meant miners scooped up some sand and pebbles from the river bed and swished the sand out of the pan leaving the heavier gold at the bottom of the pan.
