Gold is largely found in a pure form, as it does not oxidise or form other compounds (though it may be found as an alloy in some cases)
You either pan it out from river sediment, like those found in Yosemite - if found in large quantities the sand and gravel is washed over devices like shaking tables and collected.
You can extract very small particles of gold by washing the gold-bearing sand in Mercury (in which gold dissolves) and then boiling the mercury away to leave the gold, though this is not recommended at all.
Otherwise mineral seams bearing gold are crushed to gravel-sized pieces, and the gold smelted out with a furnace.
