What Is The Refining Process?
The refining process is the chemical process by which impurities are removed from precious metal. The chemical process involves dissolving the target metal and then precipitating it back out.
What is the process in which impurities are removed from a metal by dipping the metal in acid?
The process is usually referred to as pickling, or descaling.
What non metal is used to remove oxygen from metal ores?

What chemical process is used for obtaining a metal from its oxide?
Smelting removes unwanted elements from metal.
Why does bleach rust a steel nail?
Bleach works by oxidizing the stain it's treating. "Oxidize" means it removes an electron from it, so the bleach removes an electron from the stain. Rust is also formed by oxidation, the removal of an electron from a metal. So if bleach can remove an electron from a laundry stain, it can also remove one from a metal.

What is gouging in welding process?
Gouging is a process where an arc is established between a carbon rod and the metal to be gouged and the metal is melted. A steady flow of air is blown into that molten pool removing the molten metal. Increasing the amperage or slowing down the travel speed allows a deeper gouge. Speeding up the travel speed or decreasing the amperage removes less metal. Copper coated carbon rods are used and are available in different diameters and shapes.
What is smelting?
A process of taking an oreand, throughheating and adding other substances to remove other elements, gives you a purer sample of the metal.
