limestone mines process method

Mining Graymont

Consider a world without advanced manufacturing, agriculture or mass-scale energy production. Virtually all of mankind's needs must be dug from the earth, grown in the soil, or taken from the sea. It is currently estimated that we need to produce more than 40,000 pounds of new minerals a year for every man, woman and child living in the United States.
