Autoclaves are used in the mining process to extract materials such as Gold, Silver and copper from ore. NELCO is trusted by nearly all of the most well-known companies in the industry.
Autoclaves work in a similar way, but they're typically used in a more extreme form of cooking: to blast the bugs and germs on things with steam long enough to sterilize them. The extra pressure in an autoclave means that water boils at a temperature higher than its normal boiling point—roughly 20°C hotter—so it holds and carries more heat ...
