3) Temperature and pH. Cobalt is a metal that can be a bit picky when it comes to conditions in which it will electrowin. It doesn't like being too hot, or too cold, and it definitely doesn't like being at the wrong pH. Cobalt prefers a temperature range of 40-600C and a pH of below 2 or greater than 4. These three parameters are not full ...

Copper, first used in ancient times was produced by working native copper followed by pyrometallurgical processes. Fire refined, Lake copper set the standard for purity and conductivity up until this century. The first patents for metal electrorefining, were for copper and were granted to James Elkington in England in 1865.
Before breaking down the EV charging station cost, let's first see which areas we need to invest on: Charging equipment (50kW CCS + CHAdeMO): Rs.4-7 lakhs per charger. Power distribution and installation: Rs. 50k-1 lakhs. Land/Real estate cost: Variable, depending on location. Civil work & Electric setup: Rs. 5 lakhs.
