Sheng Jin, also known as natural gold, waste gold, and gold, is the object of mature gold, and is extracted from mines or alluvial deposits, and has not been melted and refined. There are two types of gold mines: gold and sand gold.
Mineral gold, also known as agglomerate gold, is produced in mines and gold mines. Most of the hot springs that flow out of the earth are precipitated by the fineness of the rocks and are often trapped in the crevices of the rocks. The ore is mined and crushed. , Washing, large gold can be picked directly, the available mercury dissolved in small particles. Most of the mineral gold is associated with other metals, among which there are silver, platinum, zinc and other metals besides gold, which was previously known as synthetic gold before other metals were proposed. Mine gold is produced in different mines and contains different metal components. Therefore, the quality varies from 50% to 90%.
Shakin is produced in the bottom or low-lying areas of the river, so the sand and sand are mixed together and washed out of gold. Shakin originated in the mine due to the exposure of gold ore to the ground. After a long period of wind and rain, the rock weathered and cracked. The gold departed from the veins and flowed along with sediments and water. It naturally settled in the sandstone, below the bottom of the river or under the sandstone. Deposited as a gold-containing layer, which forms sand gold. Shakin's characteristics are: the size of the particles is not the same, large like broad beans, small like sand, different shapes. The color varies depending on the level of color. More than 90% is reddish yellow, eight is light yellow, and seven is greenish yellow.
The cooked gold is the gold of the raw gold after smelting and purifying. Generally, it is of higher purity and finer density, and some of it can be directly used in industrial production. Common gold bars, blocks, ingots and a variety of different accessories, utensils, gold coins and industrial gold wire, film, board and so on. Due to different uses, the required color is not the same, or because there is no purification equipment, but only melting is not purified, or the purity of the mention is not enough to form different grades of gold. People are customarily divided into three types of pure gold, red gold, and colored gold depending on the level of fineness. Divided into gold by color, mixed color gold, k gold.
The gold that has been purified to a relatively high purity is gold, and generally refers to gold that is more than 99.6% fine.
The red gold and pure gold are eager to be close, but due to the difference in time and place, the standard of the red gold is different. The gold sold in the international market is known as red gold with a purity of 99.6%. The territory of the red gold is generally between 99.2% -99.6%.
Color gold, also known as "second gold" or "tidal gold", refers to gold with lower quality. Due to the different content of other metals, these golds have a high color purity of 99% and a low of only 30%.
According to the division of other metals, gold can be divided into clear gold, mixed gold, and k gold. The clear gold refers to the gold only with the silver component, regardless of the level of color known as clear gold. More clear gold, common in gold bars, ingots, blocks and various utensils and gold jewelry.
Mixed gold refers to gold, which contains silver, copper, zinc, lead, iron, and other metals. According to the different types and amounts of metals contained, they can be divided into small mixed gold, large mixed gold, bronze mixed gold, and lead mixed gold.
K gold refers to the gold made of silver and copper according to a certain proportion, according to the formula of pure gold for 24k. In general, the greater the proportion of silver in k-gold, the greener the color; the larger the proportion of copper, the purple in color. China's k-gold was calculated at the rate of k4.15% per unit in the early period of liberation. Since 1982, it has been unified with international standards, with 4.666% per k as the standard.

Gold is a natural product that can exist in the free state in nature and cannot be synthesized. According to the source of the different and the content after the refinement is divided into gold and cooked gold.
