The Merrill Crowe Process For Mining Gold
Gold is mined in the form of microscopic particles in concentrations as little as 0.5 parts per million (ppm). As a result, simple tools have been replaced by complex equipment and chemical processes to extract gold. Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows:
Copper Mining and Processing: Processing 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, …
