May 06, 2016 In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the main recovery is from the fine sands.

During phosphate beneficiation, producers use ArrMaz’s anionic flotation reagents to selectively separate the desired phosphate from the gangue with a focus on maximizing the amount of phosphate recovery possible. Just as each phosphate deposit is unique in composition, so too are ArrMaz’s flotation reagents.

Flotation separates valuable minerals (copper, lead, zinc, iron, and phosphate too) from the contaminating minerals in the ore (sand in this case). In the direct flotation process the valuable mineral is coated with a special hydrocarbon (fatty acid) that makes coated particles behave the same as a waxed car.
