Geology and mining
Gold is also extracted largely from older sedimentary placer strata and sulphide ores. The content of sulphide mineral in gold ore varies. In the Björkdal mine in Sweden, waste is produced that is reused outside the mine as road building ballast and other infrastructure. Gold ores can however also produce hazardous waste.
