So, even if the ore were ground to 2 microns, it may not be recoverable using current ...

Pyrite Mining | Processing Equipment | Flow Chart | Cases ...

2021-10-22 · What is Pyrite. Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered.

Pyrite - Fool's Gold | Mojave Gold Mining

Pyrite. Pyrite, or iron pyrite, also known as fool’s gold, is an iron disulfide mineral containing iron and sulfur. The name fool’s gold comes from novice prospectors commonly mistaking it for gold. Pyrite has a brassy sheen, and unlike gold which is malleable, pyrite will crush into a brown powder.

The best answer as to how to recover that gold depends on the amount of pyrite you intend to process. If you have only a few pounds, it can be roasted by heat in the open air and then mixed with a flux like sodium borate and melted with a collector metal like copper. The melt can be poured into a mold and the gold will now be alloyed in the copper.
