Griesheimer process with KCl

John paul III - 15-5-2019 at 07:01

According to wikipedia, potassium can be produced from fluorite ore in the "griesheimer process":2 KF + CaC2 → 2 K + CaF2 + 2 C
Shouldn't KCl work better? Also, i have been unable to find detailed conditions of the process, so im sceptical of it's usability for an amateur

Apparently, you can use KCl, as this excerpt from the Kirk-Othmer Encyclopaedia vouches (see attachement).
