RE:RE:New to this oneHudson's product will be a replacement for Kaolin in the production of e-glass. 2017 Kaolin prices averaged $160/ton. Hudson's Greenspar is superior to Kaolin and will fetch higher prices. The cost to process the anorthosite is, i believe, $35/ton while the cost to ship is close to $30/ton.
