Among the many uses of acetylene gas, the largest and perhaps the most familiar is its use in the form of cylinder gas for metal fabrication and construction. When combined with oxygen in an oxyacetylene torch, acetylene produces a flame temperature in excess of 6,000 degrees F, the hottest flame of all hydrocarbon gases.

Sep 29, 2021 The present article reports the recovery of potassium from mica scrap using carbide lime waste and NaCl. The acid leaching of mica [4 M H2SO4 at 90 °C] can recover a maximum of 25% potassium. However, in the chlorination roasting (with CLW and NaCl) water leaching process, it was possible to recover potassium to the tune of 94% [900 °C, 50 min roasting; mica:CLW:NaCl 1:0.75:1].
