Gold ores with a very high carbon content
Thread Content
In my hometown, there is a type of ore that is black in color, contains a high amount of carbon, but also includes gold and silver. How can gold and silver be extracted? ! 2 moves from a master! !
Reply to 1# Qiu Ningjing Zhiyuan: How high is the carbon content? What is the content of gold and silver? Is it a sulfide ore or an oxide ore? Is it high in arsenic? The basic process is intensified flotation—concentration roasting—gold extraction, depending mainly on one’s own available resources.
It is estimated that only the roasting process can be used; there are no other good options.
If 1 ton of ore contains more than 2 grams of gold, it can be extracted
Reply to 1# Qiu Ningjing Zhiyuan: What was said above is correct, but it’s not clear what the grade of gold and silver is. With such a high carbon content, flotation might not work; if the ore is to be roasted, the grade of gold and silver needs to be sufficient. Currently, regulations regarding the use of cyanide are very strict, and if the scale of operation is small, the ore may end up being unusable.
