Dissolution of mechanically activated sphalerite in the wet and dry
2.2. Mechanical activation. Mechanical activation of the sphalerite concentrate was done in the wet and dry modes using a planetary ball mill (Sanaat Ceram Mehr Alborz Industry, Iran) by a rotation speed of 450 rpm. 300 stainless steel balls with a diameter of 5 mm were applied for milling by ball to powder weight ratio of 15 to 1.

Ball Mill Loading
The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
