A ball mill, which is a type of crusher, is a cylindrical device used to grind chemicals into a very fine powder to increase the surface area of pyrotechnic compositions and make the reactons take place faster. Black powder and other flammable materials require non-sparking lead antimony, brass, or bronze grinding media.

Thus, at higher milling times, mechanical activation of the mineral surface must be taking place, which makes leaching better. Download : Download full-size image; Fig. 5. Cu 12 Sb 4 S 13 leaching: recovery of antimony into leach, ε Sb, vs. time of leaching, t L. Temperature of leaching—313 K. (Milling time is given next to the leaching curves.)

You do also lose some lead and antimony by repeated melting, but this is not so crucial to the casting process as the tin content is. Bear in mind that lead makes up the bulk of the alloy and contributes mass and malleability to it. Antimony contributes hardness but at the expense of brittleness. Tin is the ingredient that 1) lowers the melting ...
