The traditional process to extract aluminum from ore involves two major processes. The Bayer process extracts alumina from bauxite via a chemical process and is usually done at the mine …

The recovery of KCl from feldspar, by assaying its 7.21% K2O, was carried out using a 1:1.25:1.5 ratio of feldspar:CaSO4:NaCl at 1000 °C for 60 min, followed by leaching, to obtain KCl with 96.1% potassium dissolution.

The extn. of potassium from K-feldspar via a calcium chloride calcination route was studied with a focus on the effects of the calcination atm., calcination temp. and time, mass ratio of CaCl2 to K-feldspar ore and particle size of the K …

Complete extraction of potassium was achieved by roasting feldspar with eggshell powder and 1.5 times the stoichiometric amount of hydrochloric acid. The optimized conditions were feldspar to ESP in a ratio of 1:1.8 at 900 °C for 30 min followed by leaching with water.

The traditional process to extract aluminum from ore involves two major processes. The Bayer process extracts alumina from bauxite via a chemical process and is usually done at the mine site. Pure alumina is exported to a smelting operation. The Hall-Héroult process uses electricity to de-oxidize alumina into aluminum metal.

Feldspar is an aluminosilicate mineral that bears potassium in the interstitial sites. To unlock the potassium from the interstitial sites, it was roasted with calcium chloride prepared by mixing...

Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process.
