Phosphate Beneficiation Process

Large scale mining and processing of phosphate is essential for operating at a profit. 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

Lecture 14 and 15, Transport

The exchange allows the chemical component of the proton gradient (-ZDpH) to drive uptake of phosphate into the mitochondrion. The net effect of these two transport processes is that the proton gradient drives the concentration of ADP and phosphate inside the mitochondrion, and the export of ATP, at the expense of 1H + /ATP synthesized.
