1. Price Secrets: The Triple Game Behind Every Gram of Silver In April 2025, the silver paste recycling market in Beijing showed a “polarized” pattern: Photovoltaic silver paste waste (containing 80%-95% silver): real-time price of 6.8-7.2 yuan / gram, up 22% compared to the same period last year, mainly driven by the explosive growth in … Read more
Recently, a “technological breakthrough” has emerged in the circuit board recycling industry! A company in Anhui has applied for a new patent, intriguingly titled “A Device for Hydrometallurgical Recovery of Precious Metals from Waste Circuit Boards”—doesn’t the name alone make you feel like precious metals are calling out to you? In simple terms, the biggest … Read more
In the recycling of waste items, a common item in the market is the circuit boards from old electronics, such as those from old mobile phones and computers, or from cars. In the past, these items were not recycled, but now they have become popular products. The recycling price for mixed circuit boards ranges from … Read more
Waste printed circuit boards (PCBs) contain high-grade precious metals and are an important part of the electronic waste value chain. However, our country lacks key technologies for environmentally friendly extraction of precious metals. For a long time, outdated processes such as open-air incineration and acid leaching have been used to extract metals, resulting in serious … Read more
Recycling Market Value The price of waste circuit boards mainly depends on the content of precious metals inside. For example, the price of a ton of waste circuit boards from TV circuit boards is around 30,000 to 40,000 yuan. A ton of computer boards typically contains about: 300-500g of gold, 130kg of copper, 10kg of … Read more
To achieve large-scale hydrogen production through water electrolysis, it is crucial to develop non-precious metal catalysts for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). Here, we prepared a tin, iron, and cobalt-based sulfide/oxide heterostructure catalyst (FeSnCo0.2SxOy/NF) on nickel foam using a solvothermal method. FeSnCo0.2SxOy/NF outperforms IrO2||Pt/C electrolyzers at a current density of … Read more
