Gold extraction - Wikipedia. 2019-2-24 · Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Iron Extraction Process. In the blast furnace process, the first step on the way towards heavy plate, pig iron is produced from iron ore. The composition of the ore and additions is accurately adjusted to the final products of AG der Dillinger Hüttenwerke and Saarstahl AG.
Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Electrolytic Gold Extraction Experiment Ore from Colorado number "A". This ore is a "rotten granite" containing a very small amount of sulphide, no telluride, a little copper and considerable iron as oxide. The gold is in a very fine state of division.
Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
3.2. Selective Gold Extraction and Recovery from Complex PGM Solutions. Once in solution as the tetrachloroauric complex, a number of commercial processes are used to isolate gold from PGMs and base metals. Reduction of gold to the metal is used for batch processes, and solvent extraction is often used for continuous processes.
Extraction of Gold by the Amalgam Process. The amalgam process is the oldest technical method of extracting gold and was used in antiquity. With the amalgam process the gold bearing rock is likewise crushed to fine sand. Afterwards mercury is added to the rock dust. Gold has the property that enables it to join to the surface of the mercury.
extracting iron from iron ore using blast furnace: Extracting iron from its ore requires a series of steps to be followed and is considered as the penultimate process in metallurgy. The steps need the ore to be concentrated first, followed by the extraction of the metal from .
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
