But if you're making HPA, you can make SGA. HPA is a rehashing of the SGA steps multiple times over.

The HPA, SGA, REE's and red mud, are all involved with experts from each respective company. All ORT has to do is process their samples, give results and say......do we do business or not? I don't think the hard work is on ORT per say. Most of their heavy lifting  has already been done. Customer orders, install, fire up and upgrade by way of calcinator(s) and  this is a totally different looking picture & ORT knows that too.....obviously. lol   Keep in mind, the 4N market is much larger then the higher purities right now. So this upgrade is actually more about bringing the future now, to ORT. Later !!
