sun trading wholesale jewelry First of all, you need to buy sand. Gold is heavier than sand. Put the gold containing gold in the water, stir up the gold with your hands, and will sink to the bottom, just get the sand above. The golden sand obtained later needs to smell or chemical replacement to obtain high purity gold and silver. For example, the sand containing gold is installed in the cup, and the matched king water is also put in the cup, so that the king water can melt into the water, and then the king water is considered. Gold was proposed. Use sieves to precipitate in the water, because the proportion of gold and sand is different. With the buoyancy of the water and the shaking of people, the gold that can be screened can be screened. Gold is a very lively metal that usually exists in a free state in nature. The density of gold is very large, so the gold is rushed from the sand. The method of washing with water can be used to extract the density from the sand. When washing the sand with water, the density of soil, fine sand and other substances were rushed to the water, and the amount of gold with very little content can be extracted. This is a way to separate the physical properties of simply using material. Other gold rush methods: (1) Released with chemicals. (2) Metallurgical, metallurgical technology mainly includes fire metallurgical, wet metallurgy, and electric metallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science.
wholesale jewelry drop shipping The method of refining sand gold into gold: There are two main methods for refining Shajin into gold, one is the fire alchemy; the other is electrolytic funds.
. Fire alchemy: First of all, crushed ore, passed the Chongsha method, enriched, and then refined in the furnace.
. The electrolytes are used to dissolve the gold in the ore with the golden library solution, and then the gold is proposed by the electrolytic method. The purity of this refinement can reach 99.9%.
wholesale price jewelry Wow, where is your hometown really lucky? Look at it.
The refinement of gold is actually more difficult. Generally, it can only be done by the factory. I advise you not to do it, because it takes more equipment to refine gold and some chemicals. Generally speaking, the gold content of rock -shaped gold ore is generally about 4 grams per ton ore. That is to say, even if it is a large gold refining plant, generally, 4 grams can be used to refine from the gold ore per ton of gold ore per ton. The left and right gold, and the landlord you only have 50 catties ore, that is, 25 kg ore. According to this, in general, at most, it can only be refined about 0.1 grams of gold. How much is gold, and your refining technology cannot reach the technical level of large refiners?
, that is, you basically cannot refine the gold. So I still advise you, it is best not to do this!
It others' refining procedures are generally crushed ore first, and then screened to obtain gold ore with higher gold content, and then use cyanide method to refine the gold. It is very complicated, otherwise, the production cost of gold will not reach about 80 yuan in my country!
pink wholesale jewelry Haha, you won't believe your words first; second, even if you really find it, you can't take the existing existing, you should pay the country!
buy hip hop jewelry wholesale I found that a piece of leaking out of the ground, the glittering of the golden light is all the same thing as fine sand and red gold.
