Milling Ore Once at the production facility, it is put through a hammer mill to reduce it down to 200 mesh minus in particle size, then fluxed and roasted to reduce ore to an oxide. It is then ball milled with steel balls to a nano particle size, to achieve the highest yield and also the highest concentration level of whatever metal or element is desired to be processed.

Drum Drying also known as Roll Drying is a continuous process that creates dry powders and flakes from a liquid feedstock. The liquid feed is sprayed onto or in between two rotating drums. The drums are heated internally with steam to increase the surface temperature. As the material is sprayed onto the drums, it sticks and dries to the surface.
