Gold ores are classified "free-milling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory gold-bearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of gold-entrapment in different associated mineral phases before an …
Remember that supply: If you just halve the supply of gold production, a hundred million ounces a year, went to 50 million ounces, gold would be $10,000. And what happened last year is that Bitcoin's supply, every 10 minutes, halved. And, there're more wallets that people are buying, and they can buy fractals.

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
'Everyone has heard of the 1849 gold rush in California, but we've had some wonderful gold rushes here too,' added Mr Thurkettle, from Norfolk, who has been panning for 32 years.
