The following link discusses "choosing between kiln and flash calciner technologies" for lithium extraction.

6 weeks ago I posted same link and I’m wondering why FFX couldn’t get a lab testwork sample out? Anyone know why? I’ve been asking for 6 WEEKS

"Conversely, a gas suspension calciner (GSC) is best suited for spodumene concentrate that has a PSD less than 1mm, which is common for concentrates produced via the floatation process. As the feed size is very small, it takes very little time to heat the sub 1mm particles to conversion temperature and once temperaturfe is reached, the conversion happens almost immediately. Therefore, unlike the rotary kiln process, the retention time of the material in the GSC is only a matter of seconds and yet the conversion is achieved just the same."

"TK: For customers dealing specifically with fine ores, we designed the Gas Suspension Calciner (GSC) technology – something we have supplied since the beginning of the 1970s. It consists of a series of preheating cyclones, a calciner vessel and a series of cooling cyclones."

IMO from this it seems the "technology" for dealing with "fine ores" is well known and has been around for quite a while

Though I can’t currently find the original academic source for my view on the ‘innovation’ or ‘novelty’, the view does stem from the fact Spodumene production convention, that it’s hard to get hr lithium to change its methods because they are a known certainty (this was 2018) and is clearly different from any 100% WOF + GSC process—I don’t see reference in that link for GSC to lithium, it could be some other ore? I don’t doubt it occurs but on what scale?? Additionally, I’m not sure “since 70’s” applies to the market FFX is exactly targeting. Question—also—here is, was FFX in SS doing this company’s GSC or is there another version for fines?—I’ve heard of ‘microwave’ in recent studies.

Also bear in mind, fines is blended with coarser material— at least that’s what GB, AJM, PLS have reported and blending is how Chinese processors can get for appearances, the certificate of chemical grade standard. Talisons (HKEX IPO pdf) for tailings feedstock, intends not to blend, but it’s not known in same document what the feedstock will be nor the customersconsidering the characteristics of grind size would appear to be similar to FFX if not larger but under 1mm, unless I missed itjgbit62 wrote:
