Zinc: smelting, producing and classificationMetalpedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in ...

Gold extraction Wikipedia

Apr 03, 2005· History. The smelting of gold began sometime around 6000 3000 BC. According to one source the technique began to be in use in Mesopotamia or Syria. In ancient Greece, Heraclitus wrote on the subject. According to de Lecerda and Salomons (1997) mercury was first in use for extraction at about 1000 BC, according to Meech and others (1998), mercury was used in obtaining gold until the …

How to Use Bleach on Gold Ore to Remove Gold | Sciencing

Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

Zinc processing | Britannica

Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal closepacked (hcp) crystal structure and a density of grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.

How to Purify Gold | Sciencing

The unpurified gold ore is fashioned into a 100ounce anode, whereas pure gold strips make up the cathode. The electrolyte solution is a mix of gold chloride and hydrochloric acid. When an electric current passes from the anode to the cathode through the electrolyte, the gold at the anode dissolves and collects at the cathode.

Retorting amalgam and recovering gold from slag

The inside of the retort is lined with three or four thicknesses of paper, with chalk, or with a paste of wood ashes, lime, or red oxide of iron, to prevent the gold from sticking to the sides. In the retort the balls of amalgam are placed so that it will not be more than threequarters full when the cover is placed on.

Zinc smelting Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, iron, because in contrast, zinc has a low boiling temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Processing, smelting and refining gold | World Gold Council

Aug 03, 2020· The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.


the oldest and most reliable method for analysis of gold and other precious metals from a wide variety of goldbearing materials (Blyth, 2004). This paper seeks to outline one such method, DC plasma arc smelting, and the circumstances in which it represents a viable alternative to more conventional approaches. DC PLASMA ARC TECHNOLOGY

The Cremation Process | HowStuffWorks

During the burning process, a second column of flame is fired up in a secondary chamber to burn off any particles or dust in the air leaving the retort, in order to reduce emissions, smoke and odors. Some retorts also have a wet scrubber in the emissions stack that sprays a mist of water so that escaping particles become trapped [source: Sullivan].
