Thats incorrect Blast
Spodumene has an SG of 3.2-3.3
Quartz is sub 2.5
So these can and have been easily seperated
Think you are confusing with the seperating of the Lithium which is a more simple process from Spodumene that it is from Petalite etc with an SG of sub 2.5
They have not embarked on this process as yet so any comments around concentrate levels are speculation
Way to early to comment on Met and my understanding is that it will be fine, its all in the process
Hope this helps
