The primary smelting process involves separating lead from ore using heat and reducing or purifying agents such as coke and charcoal. Once the lead ore is mined, it must undergo several different processes in order to be turned into usable or metallurgical lead material: sintering, smelting, and refining.

Are smelting and melting the same? Explained by FAQ Blog
Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.

What is the difference between smelting and roasting
Step 1 Smelting is the process used for the extraction of metals by heating the ore in the presence of a reducing agent like carbon (as coke or charcoal). It converts a metal oxide into the metal. Roasting is the process of heating the concentrated ores in excess of air but a temperature insufficient to melt it with a view of it.
