    No accumulation and loating gold electrowinning equipment
    No accumulation and loating gold electrowinning equipment was developed by Changchun Gold Research Institute Co., Ltd. in 1998 and entered the market. It has been used in more than 800 enterprises at home and abroad. This series of equipment is oriented to the gold-loaded carbon in the gold cyanide carbon slurry process for gold desorption and electrolysis, and the gold adsorbed on the gold-loaded carbon is produced in the form of high-grade gold mud. After decades of practical application and continuous optimization and improvement in enterprises, this series of equipment has developed to the fifth generation. Compared with similar products at home and abroad, this series of equipment has significant technical advantages, which are mainly reflected in: 1. High gold desorption rate: the carbon-poor gold grade after desorption is less than or equal to 50g/t (the same industry products are generally less than or equal to 100g/t). 2. High primary electrolysis rate: the average electrolysis rate of desorption solution is ≥90%. (The products in the same industry are generally around 70%). 3. Accurate gold balance: the actual amount of gold obtained after desorption and electrolysis is consistent with the theoretical gold content in the gold-loaded carbon. (Products in the same industry generally have the phenomenon of "floating gold or accumulative fun

    K gold, white gold, rose gold
    K gold, white gold, rose gold "AU" is a symbol used internationally to indicate the purity of gold (ie, gold content). K gold (or gold) is an alloy of gold and other metals. K gold jewelry is characterized by low gold content, low cost, and can be made into various colors, and is not easily deformed and worn. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc. according to the amount of gold. The most common "18K gold" in China's market, its gold content is 18 × 4.1666 = 75%, the mark on the jewelry should be "18K" or "750". Introduction K Jin's "K" is the preparation of the term "Karat". The complete notation is this: Karatgold (K gold), K gold is measured by: pure gold is 24K (ie 100% gold), 1K The gold content is about 4.166%. The method of calculating the gold content with "K" is based on a carob tree on the Mediterranean coast. The carob tree has a light red flower, and the pods are about 15 cm long. The beans are brown and can be made into glue. No matter where the tree grows, the size of the beans is exactly the same, so in ancient times, people used it as a standard for measuring weight. Over time, it becomes a unit of weight for measuring precious, subtle items. At that time, the measurement of diamonds and gold also used this unit, which is [Karat". It was not until 1914 that "Karat" was stipulated as a standard internationally. Everyone understands the meaning and calculation method of K gold, so it is not difficult to know how many kinds of K gold, according to international standards, K gold is divided

    Rock gold and gold mining development experience
    The rock gold name vein mine has been favored by large companies because of its large reserves and stability. Basically, the domestic veins are in the hands of these group companies. The main reason is that the group companies can make money to prepare for the preliminary preparation and exploration. . The pulse mineral resources are drying up, China's gold mining group, Fujian Zijin Mining, Shandong Zhaojin Group. They all control 80% of the mines in China and are still taking mines overseas. Finding a good vein mine can be mined for decades or even hundreds of years, but the period of prospecting is too long. For a short period of more than one year and more than three years, the cost is not what small enterprises can afford, labor costs. , material costs, equipment costs, more than one year on tens of millions of money, the cost can be imagined so difficult. Large enterprises have a stable source of continuous support, and equipment investment is also a small matter. So it seems that our SMEs have no conditions for rock gold veins? The answer is definitely yes, but the risk factor is much higher than that of large companies. The main reason for the analysis is that small companies are constrained by investment in exploration equipment and lack of geological experts. Exploration equipment, various drilling rigs , various geophysical exploration, electromagnetic exploration and other instruments are a big expense, and experts who can master these technologies are also more difficult to find. China is not without such experts,

    Gold is hard gold soft gold? What is the difference between gold and hard gold?
    Xiaobian of China Jewelry Merchants Network recently saw someone asking questions, is soft gold good or hard gold good? Professionals help answer? Gold is hard gold soft gold? I believe this everyone knows, the following is a small series of China Jewelry Merchants Network to explain in detail whether soft gold or hard gold is good? Gold is hard gold soft gold? Is soft gold good or hard gold good? Hard gold is for pure gold. After the process, the gold loses its original texture and softness. Hard gold is a special process that breaks the ionic structure of gold. The technique of one-time forming, the hard gold process is complicated, so it is higher than the ordinary gold labor, and there is no difference in purity. What is the difference between hard gold and soft gold: Hard gold refers to physical gold, but it is a "hard" gold made with new methods. Its texture is harder than ordinary gold. Also known as "thousands of hard gold." 0.005% is added with a special metal to increase the hardness to achieve the corresponding hardness. What is the difference between soft gold and hard gold: the color is the same, but the hard gold has undergone a special process to make the gold hard, and it becomes ordinary gold after the fire. Because the process is different, the price will be more expensive. Soft gold is a high-purity gold. Hard gold is a synthetic gold mixed with other metals, usually

    How to choose paper gold, gold TD, spot gold
    How to choose paper gold, gold TD, spot gold Real gold is not afraid of fire. As a natural currency and a safe-haven gold, it has long been a very popular investment tool. The resources are independent and of high value and are not restricted to any country or trade market. They are not involved in the company or the government. Therefore, investing in gold can often help investors avoid problems that may occur in the economic environment. Moreover, gold investment is the world's least tax-intensive investment project. The biggest advantage of gold is risk aversion. No matter how the international situation changes, as long as you hold one ounce of gold, you will still have one ounce of gold after 100 years. Gold investment is a permanent, timely investment. For thousands of years, gold has always exuded her radiance, charm, and with its unique characteristics - non-destructive, easy to circulate, preserve value, investment, stored value function as the first choice for people's asset preservation. No matter how history changes, the power of state is more convenient, or the exchange of currency currency, and the value of gold - forever.

    Gold formation and accumulation of gold
    Gold formation and accumulation of gold 1. The world's gold treasures are mainly buried in the form of rock gold and sand gold, in addition to associated gold. Celestial body operation, earth formation, volcanic eruption, ancient mountain movement, magma gushing, gold elements are ejected from the core of the earth and formed into rock gold; the mountains and mountains rich in gold, weathering, thunder and lightning, storms, Sandy gold is formed by landslides, mudslides, flooding, and sedimentation in stable waters of rivers. 2. According to scientific measurements and inferences, about 2.6 billion years ago, in the Archean period, volcanic eruptions brought a large amount of gold elements from the core to the mantle and the crust along the fissures, followed by ocean deposition and Regional metamorphism, the formation of the original gold source. About 100 million years ago, in the Mesozoic, due to the powerful force, the crust was deformed and pleated, and the pleats were exposed to the sea surface. The gold material activated and migrated to form a gold ore field, which is what we call rock gold. 3. In the rock-rich enrichment zone, the rock often leaves a lot of natural gold after oxidation. In the shallow layer of rock gold, after tens of millions of years of weather

    Thiosulfate gold
    Thiosulfate gold The thiosulfate is generally a sodium salt and an ammonium salt of thiosulfuric acid, which are inexpensive, have a fast immersion gold , are non-toxic, are not sensitive to impurities, and have high immersion gold index. The kinetics of gold dissolution in sodium thiosulfate solution by Baghdad Saliang et al. showed that the dissolution rate of gold is linear with temperature in the range of 45-85 °C, but in order to avoid violent decomposition of thiosulfate, the leaching temperature should be Controlled at 65.75 ° C. Rogerzhkov et al. used a thiosulfate solution containing ammonia and an oxidant to extract gold from ore into another kinetic study, which concluded that only at higher temperature conditions in the hot press leacher ( 130 to 140 ° C), in order to achieve satisfactory speed and recovery. Kakowski and others also found that copper ions catalyze the dissolution of gold by thiosulfate, which can increase the dissolution rate of gold by 17 to 19 times. China's Jiang Tao, Cao Changlin and others have conducted a detailed study on the mechanism of thiosulfate gold extraction. However, due to the high requirement of the thiosulfate method and the chemical instability of the thiosulfate, this method has not been popularized and applied.

    Gold, Platinum (Platinum) and K Gold knowledge
    Gold, Platinum (Platinum) and K Gold knowledge Gold Gold, a yellow precious metal with a chemical symbol of Au, is high in density, soft, corrosion resistant, and ductile is the highest among the metals known. The purity of gold is represented by K (Karat). 24K is 100% pure gold, so it is the most expensive, because the characteristics of gold are the softest and impatient, so most jewelry will use K gold to achieve the required hardness, durability and color. Platinum (Platinum abbreviation Pt, also known as platinum, pure platinum) It is a precious metal that is naturally produced by high density, ductility, toughness, gemstones, and grayish white. Even at high temperatures, it exhibits significant resistance to corrosion and is therefore considered a precious metal. At the same time, the density of platinum is quite high, and the same volume of platinum will be much heavier than gold and K gold. In nature, platinum reserves are rarer than gold. The annual output of world platinum is much less than that of gold. In addition, the melting point of platinum is high, and it is more difficult to purify smelting platinum than gold, and the energy consumption is higher. More
