What is the difference between gold and sand gold? What is the difference between sand gold and gold

1. The color of sand gold varies according to the color of the color, more than ninety percent is red yellow, eight becomes light yellow, and seven becomes blue-yellow; **Golden yellow and shiny.

2. Shajin has not been refined, so it can be called "raw gold"; All the best on the market have been purified and have high gold content, which is called "cooked gold". Therefore, **of** is more expensive than Shakin.

3. Sand gold is only naturally formed, and ** is not only refined and produced, but also naturally formed gold ore.

How to clean **:

1. Roll a piece of cotton with a popsicle or matchstick for a gem-encrusted ring, wet it in a mixture of flower water and glycerin, scrub the gemstone and its frame, and then polish the ring with a flannel cloth. Do not scrape with sharp objects such as razors.

2. Salt and vinegar are mixed into a cleaning agent, and it is used to wipe pure gold jewelry, which can make it last forever.

3. Wipe with toothpaste or scrub with hot thick rice soup to restore luster.

4. It can be scrubbed with ammonia.

How to discern **:

1. Real gold is not afraid of fire, put gold bars or gold jewelry on the fire for a while to observe its changes. Because iridium will oxidize with oxygen in the air, gold bars of insufficient purity will turn gray; Pure gold, on the other hand, will be red and shiny in color after being roasted by fire. However, this method may be destructive to jewelry.

2. To measure the specific gravity, first measure the weight of a pure gold bar with a balance, then put the gold bar into a measuring cup, and pour water to submerge the gold bar. Then put the gold bar to be tested into the measuring cup, observe whether the scale of the water rises or falls, as long as it changes, it means that the gold bar is not pure gold. However, this method does not apply to gold jewelry, because there is air in it.

What is sand gold and what is the difference between it? Today I know it.

Sand gold is also a kind of **, produced at the bottom of the river or low-lying areas, mixed with stone sand, is washed out of the **, the gold content of the two is different:

1. The gold content is different: the gold content of sand gold is low, and the gold content is about 5%, while the ** seen in China is all pure gold, and the gold content is in.

2. Different degrees of softness and hardness: Shajin is hard, while China** is soft.

3. Different colors: The color of sand gold is golden yellow at first glance, and it is whitish when you look closely, and the color is real golden yellow.

Answers for you.

The differences are as follows: Shajin and ** can be seen in four aspects, namely gold content, purity, price, and feel. The specific differences are as follows:

1. The gold content is different. Shajin is also one of the best, but the gold content is low. **The gold content is above, and the content of sand gold is generally 30%-40%.

2. The purity is different. Sand gold is also gold ore purification** is now a popular jewelry, the same as **color, the difference is mainly in the purity, washing and refining the sand gold, the purity is equivalent to 20 **.

3. The price is different. Shajin jewelry** is much cheaper than**jewelry**. A 100-gram men's ** necklace costs more than 30,000 yuan, and Shajin only costs a few hundred yuan.

Together with rings and bracelets, a maximum of 1,000 yuan is enough. 4. The feel is different. The jewelry made of Vietnamese sand gold will feel harder than the ** jewelry.

What is the difference between Shajin and **.

Sand gold is gold mixed with sand and gravel, which is fine gold formed from metal veins, which are consumed by flowing water or falling rocks and fall off ore veins into fine sand or water, and finally combined with other sand and gravel impurities. The size of the sand gold is different, and the parts are the same, some are the size of stones, and some are as small as fine sand, which can be said to be different shapes and postures. The color is also different because of its own ** amount, the high gold content is darker, and the low gold content is lighter.

**, is a mineral with a very high gold content, and its purity is usually expressed by how many k. The purity of sand gold is far lower than that of an ordinary **, and sand gold needs to be extracted and purified to become ** in our traditional concept.

The origin of sand gold is different, it is produced in ores and mines, and sand gold is produced in the riverbed area, and the color of sand gold is also different, the gold content of blue yellow is 70%, the gold content of yellow is 80%, the gold content of purple yellow is 90%, and the gold content of red yellow is 100%.

How to distinguish between Shajin and **? Keeping these points in mind will make it easy to distinguish between the real thing.

What is sand gold and what is the difference between it? Today I know it.

Shajin is a kind of **, sand gold, produced at the bottom of the river or low-lying areas, so the stone and sand are mixed together, and the ** is washed out. Sand gold originated from the mine, because the gold ore is exposed to the ground, after a long period of wind and rain, the rock is weathered and cracked, the gold will be separated from the vein along with the sediment and go down the water, naturally precipitated in the stone sand, in the bottom of the river or under the sand and gravel deposited as a gold-bearing layer, thus forming sand gold. The characteristics of Shakin are:

The grains vary in size, from large ones like broad beans to small ones like fine sand, with different shapes. The color varies according to the level of color, more than ninety percent is reddish yellow, eight becomes pale yellow, and seven becomes blue-yellow.

Sand metal in the raw gold. The difference between sand gold and ** is mainly in the purity, the purity of the sand gold extracted by washing is equivalent to the ** of 95 and 96, so it is also much cheaper. If it is melted and refined, it becomes cooked gold, and thus the purity will be higher.

Sand gold is produced at the bottom of rivers or low-lying areas, mixed with stone sand, and washed out**. The size of the sand gold grains varies, from the large ones like broad beans to the small ones like fine sand, with different shapes.

1. Shajin is a kind of **, which belongs to raw gold.

2. The difference between sand gold and ** mainly lies in the purity, and the purity of the sand gold extracted by washing is equivalent to that of 95 and 96.

3. Shajin is cheaper than **.

4. There are four textures, including gold of different purities, and sand gold belongs to one of them.

Sand gold extraction** is based on the physical properties of the mineral, does not do chemical treatment of the raw ore, does not change the properties of the original sand gold, so in terms of purity, it is not as high as sand gold refining. Because the purity of sand gold is changed by fire method and electrolysis method.

The method of refining sand gold: There are two main methods of refining sand gold, one is fire alchemy; One is electrolytic withdrawal. Fire alchemy is to first crush the ore, enriche it through heavy sand processing, and then refine it in a furnace; Electrolytic gold extraction is to use sodium cyanide solution to dissolve the gold in the ore, and then put the ** out through the electrolysis method, this refining method, the purity of gold can be achieved.
