What did the European miners eat?
California gold miners didn't eat "in the mines" they ate at their camp. Usually it was very simple food since everything was cooked over a campfire. Pancakes were popular, eggs (though they could be expensive in the camps), beans, hardtack, (thick, stone hard crackers) coffee was popular, dried peas, chicken, rabbit, and a steak if they found gold. It was a rough life and often the men were sick, wet, and dirty. Bread was an important staple in any miners diet. It was cheap, and easy to make. Many miners cooked their food, and even baked bread in a "Dutch Oven", a large, cast iron pot with a tight fitting lid. They first made their own yeast by allowing flour and water to ferment in a warm place, this was the "starter" for sour dough bread, biscuits, pancakes and more. When the starter was mature, they would take a scoop out, add flour and make the bread dough. They let it rise in the dutch oven near the fire while they slept. In the morning they would dig a hole next to the fire, put hot coals into it, put the dutch oven in, add more coals, and cover it over with dirt and go off to their mine to work. When they came back to camp at the end of the day, the bread was baked and ready to eat.

Why gold and platinum not corrode in air?
(Copying verbatim from my pre-registration answer)
Gold and Silver (and other Noble Metals like Iridium and Palladium) do actually corrode in air, just very very VERY slowly. Bonding with Oxygen is the usual source of chemical corrosion here on Earth, and every metal has its own personal "preference" for bonding with more of itself vs with Oxygen. Iron, for instance, likes Oxygen a lot, and turns into rust without much effort at all. Gold much prefers more Gold to Oxygen, so for the most part, it doesn't corrode. Metals which have very stable structures in a galvanic (electrochemical) sense don't tend to bond to Oxygen very often. Gold and Silver are two of these metals.

You take the metal ores - in the case of bronze, you need 1 copper + 1 tin for every bronze bar - to a furnace. Alternately, you can use the "Superheat Item" magic spell.
