抄録

This is a report of studes on the extraction of potassium in Kali-rhyolite by the thermal treatment with the chlorides, obtained in the chlorination of titanium-containing ores (ex. titanium-slag, ilmenite).<BR>The chlorides that contains FeCl2, MgCl2, AlCl3, etc. occurs as the by-product in the chlorination pro cess.<BR>To make potassium in Kali-rhyolite water-soluble, Kali-rhyolite was mixed with the chlorides and heated for several hours.<BR>The potassium in the ores was almost completely (max. 95%) extracted when the mixture of the chlorides and ores (ratio 1: 2 in weight) was heated for 5 hrs at 800°C. The product was further treated with air at 800°C for 3 hrs to change the chlorides except potassium salt to unsoluble oxides. The product may be used as the fertilizer containing water-soluble potassium.
