   Understand the basics of refining. We are proud of the recovery of precious metal scrap to refine gold, silver, platinum and palladium. The experience of several generations and the mission of continuous improvement throughout the company have helped us perfect the precious metal refining technology. The home workshop refined precious metals company uses a combination of cutting-edge technology and industrial innovation to best refine your gold and silver. We are always happy to talk about our process, please feel free to email or ask any questions. What is an alloy? Metals are often mixed or melted together to form so-called alloys. Alloys are created because their performance may be better than pure component metals. Some metals are stronger, others are less corrosive, and others look better. For example, stainless steel is made by mixing chromium with steel. Alloys are commonly used in all dental metals and most jewelry metals. What is analysis? Laboratory testing is an investigation procedure that assesses the properties of unknown substances. In precious metal refining, a measurement method can accurately identify the metal contained in the alloy. In short, testing is how we determine how much gold you have and how much you pay for the metal. What can be refined? Refining is the process of purifying impure substances (whether oil, sugar or metals). The simplest method is to consider precious metal refining as a recycling method-a process that separates products or by-products (such as industrial, electronics, dental or jewelry) that contain precious metals and restores them to a pure state for recycling. What happens after the metal is purified? Once the precious metals have been repurified, they can be put back on the market. There it can be bought as an investment or used to create new products. The precious metals in the industrial waste produced in the manufacturing process have been widely used for the recycling of precious metal scrap. For these recycling prices, confidentiality should be ensured when processing waste, and recycling operations should be carried out in segregated batches with high recovery rate of precious metal scrap, short operation time, and low processing cost. In recent years, waste recycling has faced three major challenges. First of all, because precious metals are replaced by other non-ferrous metals, the content of precious metals in scrap has decreased. The second problem is that the waste is contaminated with metals that are not present in natural ore. These pollutants pose challenges to the extraction and purification of precious metals. The third challenge is to comply with Japan’s recently tightened environmental regulations, which restrict the continued use of some chemicals such as nitric acid. This report will discuss the efforts of precious metal recycling companies to overcome these challenges.


 

   Because of its unique physical and chemical properties, precious metals have been widely used in various fields. Generally speaking, they are valued for their scarcity and luster, and are circulated in almost all countries as jewelry and currency. In addition, due to their corrosion resistance and electrical conductivity, they are widely used in various industrial fields. For example, gold and silver have excellent electrical conductivity and better corrosion resistance than copper; they are widely used in the manufacture of electronic components and semiconductors. Platinum, palladium, and rhodium not only have high melting point and heat resistance, but also have unique catalytic activity, corrosion resistance and oxidation resistance, so they are used as automobile and petrochemical catalysts. Generally speaking, the unit price of precious metals is significantly higher than that of other base metals. Therefore, people have conducted industrial application research on alternative metals. So far, the practical application of alternative metals is very limited; therefore, in the near future, precious metals still seem to be the basic materials of industry. In recent years, the violent fluctuations in the price of mineral resources and the damage or pollution of metal mines to the environment have constituted serious problems. As a result, metals in scrap products are more expensive than ever before. The historical economic rationality of precious metal prices has accelerated the recycling price of metal materials. The price per gram of silver scrap is due to its value, and scrap products containing precious metals are usually recovered at the price of precious metal scrap. Therefore, compared with other products, it is reasonable that the recycling rate of scrap containing precious metals is higher. Typical examples are photographic film (silver), photographic developer and fixer (silver), end-of-life electronic products such as printed circuit boards (gold, silver and palladium) and automotive catalysts (platinum, palladium and rhodium). In some printed circuit board and capacitor manufacturing plants, semiconductors and capacitors of substandard quality appear. These things are treated as waste. In this article, these waste materials are referred to as "craft waste".


 
   Residues and waste materials such as electroplating tank waste liquid and scrap catalysts in petrochemical plants usually contain precious metals. For manufacturers, process waste, waste liquid and precious metals contained in materials are important resources, so they need to be collected and reused. To meet these needs, there are service providers that collect and refine precious metals in home workshops. Precious metal refineries are generally divided into two categories. The first group was formed by mining companies, which started by smelting non-ferrous metals such as copper and zinc. They can use non-ferrous metal smelting technology, mainly large-scale fire smelting and wet smelting, to effectively extract precious metals in family workshops. The second type of company consists of companies that specialize in processing precious metals and associated precious metals. Unlike mining companies, they usually only use small-scale hydrometallurgical processes. The family workshop refining belongs to the latter. There are many noteworthy comments on the recycling of precious metals. Scrap Gold Prices In this article, from the perspective of precious metals, we discuss the current status of precious metal recycling prices and the challenges they face. Songtian Oil Refinery Sangyo is a unique company with three main departments: the food department as a global food raw material trader, and the environmental department as the Industrial waste treatment companies, as well as the precious metals sector. In the precious metals business, we mainly recover gold, silver, platinum, palladium and rhodium. The family workshop refinery established and operated foreign subsidiaries, mainly in East Asia, to collect craft waste from local companies. The process of exporting precious metals from Japan is possible, and we can refine them from overseas subsidiaries. In addition, if necessary, a series of on-site precious metal scrap recycling systems can be introduced into the manufacturing process production line. 5) Regarding the environmental protection business of home workshop extraction companies, we have official licenses for collecting and transporting industrial waste in 47 prefectures in Japan; therefore, we can strictly abide by the legal requirements, and the current price per ounce of precious metal is collected from manufacturing plants across the country. And scrap. Cooperate with local commissioned waste disposal suppliers to detoxify and recycle these waste liquids and materials. 6) The waste liquid discarded in our precious metal refining process is detoxified internally. In particular, our high-temperature reactor was activated when the law prohibited dumping photographic wastewater into the ocean in 1995. It was the first device in Japan to decompose and detoxify high-biochemical oxygen demand (BOD) waste liquid based on the submersible combustion method.
