Gold is usually found alone or alloyed with mercury or silver but can also be found in ores such as calaverite sylvanite nagyagite petzite and krennerite Most gold ore now comes from either open pit or underground mines The ores sometimes contain as little as 5100 of an ounce of gold

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
