How do you heat lead above its melting point outside a lab situation to separate gold from lead?

You need access to a smelting furnace, crucible, and safety accessories.

Not true. Lead's critical temps are:

Melting point 600.61 K

(327.46 °C, 621.43 °F) Boiling point 2022 K

(1749 °C, 3180 °F) Heat of fusion 4.77  kJ·mol−1 Heat of vaporization 179.5  kJ·mol−1

Gold's critical temps are:

Melting point 1337.33 K

(1064.18 °C, 1947.52 °F) Boiling point 3129 K

(2856 °C, 5173 °F) Heat of fusion 12.55  kJ·mol−1 Heat of vaporization 324  kJ·mol−1

>You'll have lead vapor in the air in a short time. Lead is toxic, and in the form of a >vapor, it is inhaled. The fastest way to get something into your body without using a >needle to inject it is to inhale it.

• The process is safe as long as you know what you are doing and use common sense.
• DO NOT do this process over concrete!!
• Learn about using flux BEFORE any attempts!
• FUN FACT - Humans have been smelting for thousands of years.

HAPPY SMELTING!!!

Answer 2

Heating lead to its melting point outside a lab setting is dangerous due to the risk of lead vapor inhalation, which can be harmful. It's not recommended to attempt this process without proper equipment and ventilation. Consider reaching out to a professional or using a specialized facility for gold extraction from lead.
