Gold does not occur as ores!It is naturally pure metal when extracted and doesnot need to be separated as it does ot have any chemicals.Yes,if rocks or debris is attached,then it may be crushed and the worthless rock may be removed.
It is initially done manually. In that you pick out the gold from the other rocks. After that there are various acids and chemicals that dissolve the gold and separate it from the other material
you use an ore to separate gold from impuritties
Petroleum is an oil. Gold ore is a golden ore rock, of sorts.Hope it is better than, "because it is."
The full answer depends on which gold rush you're talking about. But if you're referring to the most famous gold rush in America that occurred in 1849 in California, then most of the miners were prospecting for placer gold (as opposed to hard rock mining, where the gold is trapped inside the rock). For placer mining, the miners mostly used: - picks and shovels (to loosen and gather gold-bearing dirt for processing) - gold pans (to separate gold from the dirt) - sluice boxes (to separate gold from the dirt) - rocker boxes (to separate gold from the dirt) For hard rock mining, a lot of other equipment is needed, such as dynamite, to get the ore, crushers to crush the ore, mules and mining carts to haul the ore, mining hats and carbide lanterns, etc.
Neither its a precious metal

an ore
A magnet is used to separate iron from non-ferrous material in the pulverized ore.
rock splitters--who separate rough dimensions of rock and ore using jackhammers, wedges, and feathers
One chunk of Gold Ore sells for 47.
Gold is very inert, and unreactive to other chemicals so table salt should not affect gold at all. FYI to get gold out of ore you use seriously strong acids that oly attact the ore and leave the gold intact.
