HOw do I use Mine to get gold to my cities?
Mines have nothing to do with commerce. Mines increase shields from the tile.

Cracker has given very good advice.
Roading tiles allows that tile to generate gold when worked. Of course, some tiles generate gold without having a road on it such as a river tile, a tile with silks on it, among others. Roads on these tiles will increase the amount of gold generated. Make sure that any tiles your
citizens are working have roads. (The tiles being worked in the city view screen.)
As the game progresses and you start to wind down the expansion phase, you need to build marketplaces. I usually build them in my best cities first, the 'core cities'. Markets increase the tax revenue by 50%. What this means is, however much tax revenue a city is contributing to the treasury for a given slider position, that amount is increased by 50%.
Also build courthouses. Courthouses decrease corruption (lost gold)
and waste (lost shields) in your cities. This is a very good thing.
Build your forbidden palace in a good location. Then you will have a 2nd strong core with little corruption and waste.
When banking becomes available, banks also increase tax revenue by 50% again. When you have 5 banks you can build Wall Street. This will give you 5% interest on your treasury up to a max of 50 gold per turn. So once you have Wall Street built, try to keep your treasury balance above 1000 gold to reap the max benefits.
Slightly off subject, for research build librarys. They increase the amount of gold going to research by 50% in the same manner markets increase tax revenue. Universitys and research labs do the same.
Just remember to road all tiles being worked by citizens, build markets and courthouses in all cities, (you
probably won't need a courthouse in your capital or your FP city), and you will notice a marked improvement in your economy.
One exception here though. If you have cities that are so far away from your capital that corruption and waste are hopeless, building these will not help. They are commonly referred to as '1 shield suckland'. As you get better at the game you will more easily recoginize these cities for what they are.
One more thought. Remember that population is power in this game. Get those aquaducts built where needed so the cities can get to size 12.
More pop=more tiles worked=more gold, provided they have roads.

You may need to build more workers during the expansion phase in order to build these roads and mine those tiles. That seems to be the biggest mistake that people new to the game make. Not enough workers to keep all citizens in all cities working improved tiles.Try to have at least 1 worker for every city you have.
