WO2017178979A1 - Sillimanite separation process -

Described herein is a method to separate sillimanite from beach sand. The method includes passing the beach sand through a preliminary filter screen to achieve uniform grain size of beach sand. After this step the beach sand of uniform grain size is subjected to a magnetic separation process to separate out non-magnetic minerals of the beach sand.

Froth Flotation Process - Mineral Processing Metallurgy

Jan 20, 2021  The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

About Eriez - World Authority in Separation Technologies

In 1941, Orange Fowler Merwin, or "O.F." as he was known, sold equipment to grain millers. The most common complaints heard from his customers were about "tramp iron" - stray pieces of metal such as bits of wire, nails and bolts, even horseshoes and hammers, that somehow found their way into the grain the farmers brought to the mills for grinding.
