 Characteristics of Gold

Characteristics of Gold

Iridium (one of the platinum group metals) is one of few metals that have a higher specific gravity than gold, being 22.6. Gold is around 8 times heavier than the quartz rock which it is commonly associated with when gold is found in hardrock form. A single cubic foot of gold will weigh approximately 1187 pounds.

Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
