How to effectively find and mine ore? spaceengineers

Horizontal mining requires you to make an entry tunnel until you hit the ore, then you just start drilling into the ore. This is bit more effective than vertical mining because you spend less time digging through stone and more time mining ore. 2.) You don't really need to make quarries, since stone isn't

WHERE IS IRON ORE MINED? Technology Student

To be economically viable for mining, iron ore must contain at least 20% iron. Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year.
