Then, a small amount of ethanol (5 mL) is added to the powders to make a slightly pasty state to improve the ball milling process. Next, the paste powder was taken to the ball mill and placed in a zinc cup, the zinc mill balls with a diameter of 1 mm were placed in the cup. The cups were sealed and placed into a lab made ball-mill.

Principles of Ball Milling. Ball milling is a mechanical process that involves the rotation of a drum containing grinding media, typically steel balls, at a high speed. The materials to be milled are loaded into the drum, and as the drum rotates, the grinding media collide with the materials, causing them to break down and reduce in size. ...

The study results showed that the ball milling process was effective in breaking down the e-waste swarf and liberating valuable metals, such as silver, copper, and gold. The authors also found that the ball milling process is environmentally friendly compared to traditional methods, as it reduces the use of chemicals and produces less waste.
