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

"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 temperature 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.
