Mining industry and sustainable development: time for

Mining industries provide many of the raw materials for equipment we use daily, from aluminum cans up to electronic chips of cell phones and computers. To arrive here, metal mining steadily increased over the centuries, with occasional "rushes" for several minerals (silver, gold, radium, etc.) which occurred in connection with booms in demand.
