smelting Definition and Facts Britannica

Concentrated ore and a flux commonly limestone are charged into the top and molten matte—a compound of copper iron and sulfur—and slag are drawn out at the bottom. A second heat treatment in another converter furnace is necessary to remove the iron from the matte .

Extractive Metallurgy of Copper ScienceDirect

Hydrometallurgical extraction accounts for about 4.5 million tonnes of hode copper per year about 20% of total primary copper production . Most of this is produced by heap leaching. Heap leaching consists of trickling H 2 SO 4 -containing lixiviant uniformly through flat-surfaced heaps of crushed ore agglomerate or run-of-mine ore.

A Poor Man& 39;s Method of Smelting Gold Sciencing

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.
