Apr 24, 2017· The first step in the gold smelting process occurs when ore containing gold is mined from the earth. At this point, the crude binding matter and the gold metal need to be separated. This is accomplished by pulverizing or crushing the gold ore, and then placing it in a furnace.

Gold Smelting Process | Sciencing

Copper smelting is typically a two-stage process, with a feed of copper ore or concentrate to a roaster or sinter plant to agglomerate the concentrate and remove some sulfur. This material, along with fluxing minerals and a fuel such as coal or oil, is then fed to a furnace where a copper matte is produced.

Oxide Copper Smelting Process. Smelting oxidized copper ores to black copper, as the metal thus recovered is called, is one of the simplest of all smelting operations. The ore with flux and coke is charged into a suitable cold blast furnace; the metal is collected in the crucible until enough is present to tap out into the ingot molds.
