Gold processing methods amp gold ore extraction. of all the methods of extracting gold amp 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.
In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. highly oxidized ores generally do not respond well to flotation. advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size 28 mesh which means that ore grinding costs are minimized.
In some cases the gold in the ore is extremely fine sized, and using mercury to capture it makes sense. this is also true for operators processing large quantities of hard rock material. ive done up a web page on using mercury to capture fine gold and you can view it here. link to page.
