Abrasion Test SGS

The Abrasion Index is determined from the weight loss of the paddle under standard operating conditions. SGS's results are ranked against our AR MacPherson database so they can be compared against other ores. Feed Sample Requirements: 1.6 kg of minus 3⁄4” plus 1⁄2” ore. This can normally be obtained by taking 5 kg of ore crushed to minus 3⁄4” and screening at 1⁄2”.
