Which method do you suggest for extraction of high reactivity metals? Why?

Highly reactive metals like K, Ca, Mg, Ca etc., can be extracted by the method of electrolysis most conveniently.

The reason for the above conclusion are as follows:-

a. Simple reduction methods like heating with C, CO, etc in order to reduce the ores of these metals are not feasible yet.

b. The temperature required to carry out the above reduction is too high and very much expensive thus less economical.
