Fifty years later, the average was about 27,000 tonnes a year and in the 1740's an average of 40,000 tonnes a year was achieved. The large increase depended almost wholly on the emergence of new markets, firstly in Holland and then in England.

04/12/2020Gold Smelting The smelting process is about extracting the precious metal from its ore. The process yields about 90% of pure gold. However, this percentage of gold is not acceptable in the industry, as it comes with other minerals, such as copper, silver, iron, or aluminum. Smelting comes as the most crucial step of the entire gold mining.
