Lepidico Making The Grade, page-12

Mate I'm the first to admit I'm no mettalurgist. It was my understanding that the tin extraction processes had not been decided upon yet? And that wet magnetic seperation was being considered also. Wherein, and quoting a poster I hold much faith in, 2chance stated "the tin tungsten are concentrated (not extracted) by wet magnetic separation as the Sn/W are hosted in the Zinn. These elements, along with Lithium, are one of the last things to crystallise from melt and end up in the zinnwaldite mineral, or mineral matrix.

Important to note that it is difficult to recover tin tungsten from calcines..."

Long story short, if we can achieve the scoping study numbers based on LMax, or better, I consider this a winner, hence my investment.
