The beneficiation of kyanite ores by a new dry technology is studied. Compared to the flotation method, the method reduces energy consumption from 300 – 400 to 15 – 25 kWh/ton. Dry electroseparation has made it possible to obtain concentrates with an Al2O3 content of 59 – 60% while also producing pure quartz ("tailings").

Further, dry technologies with ancient origins (i.e., the plant uptake of gold and the triboelectric separation) may influence advancements in existing beneficiation technologies. Today, the plant uptake of gold, which is comparable to the ancient Celtic hemp process, is being evaluated in phytomining projects in arid regions.
