What's the difference between mining and extracting

Mining relates to ores and minerals, whereas extraction also includes the collection of gas and oil. Gathering occurs when gas and oil are amassed in wells in preparation for being processed and refined. Ores and other materials can usually be taken away from the site in a fairly straightforward manner; however this cannot be said for oil and gas, regardless of whether it is extracted .
