Guinea Plans Five Alumina Refineries by 2030, Aiming to Boost Aluminum Value Chain

According to the latest news, Henan Shifang New Materials Co., Ltd. plans to build a project with an annual output of 150,000 mt of colored aluminum products, with a total investment of 200 million yuan. Currently, the project is in the public notice stage for the approval of the environmental impact assessment document, with the public notice period lasting from May 25, 2026 to May 29, 2026.

Research originating from Dartmouth College showed that aluminum-based reflectors can help improve Wi-Fi signal coverage. By using 3D-printed reflectors coated with aluminum foil, researchers increased signal strength in targeted areas by about 6 dB while reducing unwanted signal leakage by around 10 dB. The principle is based on aluminum’s ability to reflect radio waves and redirect wireless signals toward desired areas. Although the popular “aluminum foil Wi-Fi hack” seen online is only a simplified version, the research demonstrated practical potential for aluminum reflectors in wireless signal management and future communication applications.

Alcoa shares climbed sharply as LME aluminum prices reached their highest level in four years amid concerns over potential Chinese production cuts and continued Middle East supply disruptions. On May 26, LME three-month aluminum prices rose to USD 3,682/t, while the cash offer price reached USD 3,759/t, the highest level since March 2022. Alcoa shares increased from USD 71.38 on May 22 to USD 74.57 on May 26, gaining about 4.5%. Markets remain focused on possible output restrictions at Chinese smelters linked to energy and environmental inspections, while Middle East tensions continue to tighten global aluminum supply expectations.
