2021-6-13 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. Pyrite Uses

gold deposits, zoned pyrite contains a high gold concentration, and gold in the outer accretion zone is often higher than that in the core. Gold concentration in pyrite and arsenopyrite ranges from below one ppm to several hundred ppm. Possibly the most Au-rich pyrite was reported from the Emperor gold deposit in Fiji, which contained

2013-1-13 One USBM paper summed up five noticeable characteristics of auriferous pyritic ores. The gold occurs as tiny flakes on the crystallographic planes of the pyrite. The gold flakes are very small in size, 5-10 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite).

2021-5-26 If it is with the pyrite straight cyanidation or flotation can do the job. If the gold is in the pyrite it is a different ballgame. There is a process of nano grinding the pyrite ore, usually a concentrate, in an attritior with a solution of sodium thiosulfate. I have been experimenting with this and have been getting in the high 90's recovery.

The metal sulfide is mainly pyrite, and some are copper pyrite and bornite. The gold mineral is mainly natural gold, and some are electrum. The metal oxides are mainly speculative and siderite. The gangue minerals are mainly quartz, sericite, etc. The processing technology uses one-stage grinding, preferential flotation process.

2013-1-13 The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).
