Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

It is applicable to ores rich in silver, and also to refractory ores containing arsenic and antimony, for which the other processes are unsuitable. Parting of Gold from Silver The parting of gold from silver is effected by melting the raw product with sufficient silver to make the ratio of the gold to silver 1:3, or " quartering," the alloy being then treated with concentrated sulphuric acid

The Gold Fire Assay Process of ores is almost universally conducted in the dry procedure by furnace methods. Exceptions will be noted later. The plan of operation is to concentrate the precious metal in a button of lead either (1) Fire Assay By fusion in a crucible; or, more rarely, (2) Fire Assay By scorification.

Hello forum. Im working with an ore that contains over 15 ounces au per ton. I crush the ore but not to powder. I then screen the ore which concentrates a ton to around 25 gallons of material. The problem is the au is 100 mesh minus. I have a miller table but the process is slow and its...

The process of gold ore processing and production mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed-circuit crushing is more modern and suitable for high-hardness gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;

It is true that once you get to processing large enough amounts of ore you are likely to need environmental permits, etc., depending on the location you are working in. Most prospectors will choose to stay small, but even on a small scale, you can be processing gold-quartz ores recovering some very good gold and getting into real hard rock mining.

The ores, which have been met with in various parts of the world, consisting mainly of limonite or hydrated oxide of iron, and in most cases believed to be the result of decomposition of pyritic ores by atmospheric agencies, are also extremely refractory, causing the mercury to sicken rapidly, and yielding only about the same percentage of gold as can be obtained from unoxidised pyrites.

The processing results in comparatively pure concentrate of gold dust (with impurities < 5 %) or "amalgam sponge" or directly gold bullion. Remark:
Flotation is a typical mineral ore processing method based on the difference of the physical and chemical property and floatability between valuable minerals and veins. Technically, flotation can be used in almost all of the mineral separation. It is especially efficient to process metal and non-metal minerals like copper, pyrite, iron, gold

Gold Ore is basically gold as a mineral mixed with other sediment and minerals. In order to turn that gold ore into gold you need to process that ore. There are a few different ways to process that and neither interest me at this time. I will post links eventually on these processes.

Refractory Gold. The last type of gold deposit is called refractory gold, and it is the most difficult type to extract. It can be defined as any ore that responds poorly to a conventional gravity-cyanidation process with examples including copper porphyry, complex sulfides, arsenopyrite and lead-zinc associations.

Gold extraction. Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870. Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes

Gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. It is not uncommon for prospectors, especially those who operate metal detectors , to find a rich gold bearing specimens of ore.

The gold occurring in the alluvium is not refined by any of Nature’s processes—but the accompanying minerals or metals are either oxidised or removed hence, in the recovery of gold from reefs impurities are often collected and introduced, thus making it of lower value than the corresponding alluvial gold, and also giving rise to erroneous and widespread statements to the contrary.

Real gold is a very rare and valuable metal. Because it''s so rare, finding large pieces of gold in nature is unusual. However, you might be able to find smaller pieces of gold inside of rocks like quartz!
