3 stages of refining metallic minerals
Gold processing | Britannica
Egyptian wall reliefs from 2300 bc show gold in various stages of refining and mechanical working. During these ancient times, gold was mined from alluvial placers—that is, particles of elemental gold found in river sands.

gcse 1. Introduction to the Extraction of Metals method ...
A mineral can be a solid metallic or non–metallic element or a compound found naturally in the Earth's crust. Mineral ores are naturally occurring rocks that provide an economic starting point for the extraction and manufacture of metals for a huge variety of purposes ie a metal ore is rock containing sufficient metal to be worth extracting the metal from it.

Poling (metallurgy) Wikipedia
Poling is a [metallurgical] method employed in the purification of copper which contains copper oxide as an impurity and also in the purification of tin ("Sn") which contains tin oxide (stannic oxide or "SnO 2") as an impurity. The impure metal, usually in the form of molten blister copper, is placed in an anode furnace for two stages of refining.

STEP 3 – Settling: Settling is achieved primarily by using gravity, although some chemicals are added to aid the process. Just as a glass of sugar water with fine sand suspended in it will separate out over time, the impurities in the slurry things like sand and iron and other trace elements that do not dissolve will eventually settle to the bottom.
