Another gold extraction method is flotation. The ore is put in the solution that has the frothing agent all along with the collecting agent and the organic chemicals. Frothing agent turns this solution into the foam. This collecting agent bonds the gold, and creating one oily film that can later attach to the air bubbles surface. Organic chemicals will prevent gold from getting bonded to other material. Then air is passed …

Gold panning is the easiest and quickest technique for searching for gold, but is not commercially viable for extracting gold from large deposits, except where labor costs are very low or gold traces are substantial. Panning is often marketed as a tourist attraction on former gold fields. Before large production methods are used, a new source must be identified and panning is useful to ...
Extracting Gold | HowStuffWorks
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. The gravel-like material then enters rotating drums filled with steel balls…
What is Gold Extraction? (with pictures) - wiseGEEK
13.05.2020 · Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or stone means. The ore is typically mined first, though this is not always necessary, and then subjected to an extraction method appropriate for its ...

Extraction of Iron . Iron sits below carbon on the reactivity series and so can be extracted by reduction methods.; Iron ore, carbon and limestone are mixed together and fed into the top of the blast furnace and hot air is blasted in at the bottom.; Carbon monoxide reduces the iron(III) oxide in the ore to form iron, which will melt and collect at the bottom of the furnace, where it is tapped off:
