Refining is the process of purifying an impure metal. It's easiest to think of precious metals refining as a method of recycling. The refining process takes products or byproducts containing precious metals (such as jewelry or dental scrap) and isolates the metals back into more purified states for recirculation.

— In metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. With some borax, heat, and a little know-how, it's possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.

— Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
