Aplite Rock - Processing Solutions

Materials:Aplite Rock

Featured Product:  - RE Roll removes ferrous oxide

Problem:

The ferrous oxide content of aplite rock remained too high after removal of denser minerals from the feldspar. Glass grades of feldspar typically contain less than 0.1% ferrous oxide.

Solution:

M&T Chemicals, Inc. (now U.S. Silica), in Montpelier, VA, USA installed three Eriez Induced Magnetic Roll Separators*. Glass grades of feldspar were achieved at the desired production rate of 15 TPH and maintenance was significantly reduced.

*Alternative equipment includes Rare Earth Roll Separators.
