The sheer size and scale of new ore processing operations, with the aim being to substantially increase product throughput, means that primary semi-autogenous grinding (SAG) mills have grown to larger ...

How are nanoparticles generated? The “Bottom-Up” technique synthesizes particles from molecules or atoms. The “Top-Down” technique involves reducing the size of larger particles to nanoscale, for ...

A gold-coated milling vessel for ball mills proved to be a real marvel: without any solvents or environmentally harmful chemicals, the team was able to use it to convert alcohols into aldehydes. The ...

Automotive catalysts, among others, and materials for dental implants could become more robust and easier to manufacture than ever before. This is because chemists at the Max-Planck-Institut für ...
