Gold is mined in 41 countries, the main reserves being concentrated in the USSR, the republic of South Africa, and Canada. Physical and chemical properties . Gold is a soft, very plastic, and ductile metal (it can be hammered into leaves as thin as 8 × 10 5 mm and
Each year, global gold mining adds approximately 2,500 3,000 tonnes to the overall above ground stock of gold. While gold production has shown an upward trend in recent years, this is likely to level off in coming years.
