Effect of Solution Composition on the Passivation of Anode in Copper Electrorefining

Journal of MMIJ, 2017
To elucidate the effect of solution composition on the passivation of anode in Cu electrorefining, the potentiodynamic polarization curves were measured by polarizing from -0.2 V versus NHE to 1.0 V using the potential sweep method at 1.0 mV·s−1.

Selective Leaching of Gold from Copper Anode Slime Using Concentrated Hydrochloric Acid and Hydrogen Peroxide

Journal of MMIJ, 2019
Leaching of copper anode slime using hydrochloric acid (HCl) and hydrogen peroxide (H2O2) is performed to recover Au. It is imperative to reduce the amount of the costly oxidizing agent, H2O2, used in this leaching.

A Green Anodic Electrolysis Strategy for Recovering Copper and Selenium From Cuprous Selenide

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Selenium, a rare strategic metal, is essential for advanced technologies and biological systems. Cuprous selenide (Cu2Se), a selenium‐rich compound found in copper anode slime and a promising thermoelectric material, holds great potential for recovery.

Domed‐rim microbial polygons and their preservation potential

The Depositional Record, Volume 12, Issue 1, February 2026.
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Borate‐Water‐Based 3D‐Slime Interface Quasi‐Solid Electrolytes for Li‐ion Batteries

Advanced Materials, Volume 37, Issue 41, October 16, 2025.
This advanced material, composed of lithium borate, lithium salt, and water, is a quasi‐solid that can be handled in air and has a 3D‐conducting‐interface network (3D‐Slime‐Interface Quasi‐Solid Electrolytes: 3D‐SLISE). The 3D‐SLISE is nonflammable and can be used in lithium‐ion batteries, and its water solubility allows direct recycling of active ...
