I don't think you can always use melting points, because alloys, depending on the composition (looking at phase curves) can have one common melting point. Here's a phase diagram for a copper-nickel alloy, which I think is a system where both components are completely soluble in one another in all ratios.

You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.

was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold.

In fact, copper was the first metal to be smelted, followed by silver, tin, and lead. Other more challenging ores like those that contain iron, mercury, and gold came later. Different techniques were refined to separate these metals from worthless elements like silicon dioxide (quartz) in host rock.

The mixture is heated to temperatures above 1200°C, causing the copper to melt and separate from the slag. The molten copper, now called matte, is drawn off from the bottom of the furnace, while the slag floats to the top and is removed. Converting Process. After smelting, the molten matte is further purified through a process called converting.
