Recovery vs. mass pull: The link to air recovery

This is broadly summarised in the schematic in Fig. 12 which shows that by increasing air rate from As Found to PAR, as at Modikwa, an increased mass pull and recovery are obtained for a small drop in concentrate grade. Conversely, dropping the air rate to obtain PAR conditions yields both a higher grade and recovery, with a drop in mass pull.

Ankle Sprain Recovery Time Sports Injury Info

A grade II sprain that swells up like a balloon will take significantly longer to recover than one that only swells a little bit. This is why the Rice principles are so important, especially ice and compression. The less swelling initially, the less time it takes to get rid of the swelling. And that speeds up ankle sprain recovery.
