• There is still room for further upward movement in the price of gold

  There is still significant room for development in China's gold ETF market. On March 28, 2003, the World Gold Council innovatively launched the world's first gold ETF - Gold Bullion Securities, which was listed and traded on the Australian Stock Exchange. On November 18, 2004, SPDR Gold Trust, the largest and most liquid gold ETF today, landed in the United States and was listed for trading on NASDAQ. The fund is initiated by World Gold Trust Services, a subsidiary of the World Gold Council, with the custodian being Bank of Mellon in New York, responsible for calculating daily net asset value and other daily management. The custodian of gold is HSBC US Branch, and gold will only be sold upon redemption and operating fees. Due to SPDR being the most popular gold ETF in the world, its product characteristics have become the standard for non leveraged gold ETFs.

• Despite the recovery in demand, the production of Japanese copper smelters still shows a decline

  Changjiang Nonferrous Metals Network News: According to foreign media reports, Reuters has calculated that although demand has recovered from the downturn during the pandemic, Japan's refined copper production in the first half of the 2021/22 fiscal year will decrease by 1.9% year-on-year, according to plans from Japanese smelters.

• Testing the Content of Precious Metal Ruthenium: Latest Market Trends in High Purity Ruthenium Palladium Powder Recycling

  Ruthenium is a hard and brittle multivalent rare metal element with a light gray color, with the element symbol Ru. It is a member of the platinum group metals and contains only one billionth of the earth's crust. It is one of the rarest metals with stable properties and strong corrosion resistance. It can withstand the corrosion of hydrochloric acid, sulfuric acid, nitric acid, and aqua regia at room temperature. Ruthenium is the cheapest metal in the platinum group, although other metals such as platinum and palladium are more abundant than ruthenium.

• What's wrong with platinum and diamond rings turning yellow?

  Platinum is a natural white metal with the property of never changing color, which is loved by young consumers. This has also led many couples to choose platinum diamond rings as their first choice for wedding rings. But during the wearing process, some consumers also find that their platinum diamond rings turn yellow. So, what is the reason for platinum diamond rings turning yellow?

• Scientists invent new technologies to promote precious metal recovery

  Recently, a team led by Li Hexing and Bian Zhenfeng from the Key Laboratory of Resource Chemistry of the Ministry of Education at Shanghai Normal University has invented the "photocatalytic dissolution of precious metals" technology, which has achieved efficient and green recovery of precious metals in scrapped electronic devices and is expected to promote changes in the field of precious metal smelting. The figure shows the electronic equipment waste before and after being treated by the "photocatalytic precious metal dissolution" technology by researchers, and the electronic equipment waste after treatment is shown on the right.

• Why can recycling scrap metal reduce environmental pollution?

  Heavy metal pollution is different from the pollution of other organic compounds. Many organic compounds can be purified through physical, chemical, or biological processes in nature to reduce or eliminate their harmful effects. However, heavy metals have enrichment properties and are difficult to degrade in the environment. At present, due to the mining, smelting, and processing of heavy metals in China, many heavy metals such as lead, mercury, cadmium, cobalt, etc. have entered the atmosphere, water, and soil, causing serious environmental pollution. Even if the concentration of heavy metals discharged with wastewater is small, they can accumulate in algae and sediment, be adsorbed on the surface of fish and shellfish, produce food chain concentration, and cause pollution. Whether metals are beneficial or harmful in water depends not only on the type and physicochemical properties of the metals, but also on their concentration, valence state, and form. Even if the concentration of beneficial metal elements exceeds a certain value, they can have severe toxicity, causing poisoning and even death of animals and plants. Metal organic compounds (such as organic mercury, organic lead, organic arsenic, organic tin, etc.) are much more toxic than corresponding metal inorganic compounds; Soluble metals are more toxic than particulate metals; Hexavalent chromium is more toxic than trivalent chromium, and so on.

• Jin Hao Ba Jin: Gold Shock or Unilateral Gold and Silver Operation Suggestions

  April 6th is still a crucial week ahead, as it is a short-term and long-term battle; The debate over the impact between the US March non farm payroll data and the Biden administration's new infrastructure plan. The surge in gold is due to market expectations that Biden's $3 trillion new infrastructure plan will trigger a new round of inflation, benefiting safe haven assets and gold. However, despite last Friday's vacation, the non farm payroll data for March in the United States was still released as usual. Data shows that the non farm payroll in the United States increased by 916000 in March, the largest increase since August last year, far exceeding the expected increase of 660000. Last month, it increased by 379000, significantly bearish on gold. So, data is short-term bearish on gold, while fundamentals are long-term bullish on gold. This is a battle between the short and long term, and although the direction remains bullish, the selection of entry points is crucial.

• How was the Sanxingdui Gold Mask unearthed?

  The teachers and students who participated in the excavation work at the School of Archaeology and Museum of Sichuan University still have vivid memories of the excavation process of the golden mask. They told reporters that the golden mask was first discovered on January 5th in a sacrificial pit. At the beginning, due to only cleaning out the partial parts of the goldware, it did not attract much attention from everyone. As the fill in the pit was cleared layer by layer, the scope of the gold artifacts exposed became larger and larger, and everyone realized that this may not be a common artifact.
