Extracting copper from other ores Copper can be extracted from non sulphide ores by a different process involving three separate stages: Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulphuric acid to produce a very dilute copperII sulphate solution

Gold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Interested in The processes of smelting or roasting your ore to recover its gold and silver? Some fairly rich ores require a lot of work to get all the gold and silver out them Historically, smelting and roasting of ores have been used to capture the gold from difficult to treat ores

Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets This page offers a comparative review of gold recovery

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
