Extraction of Gold by ? | Yahoo Answers
Oct 12, 2007· The material that you want to separate the gold from is the cathode, a piece of the pure metal, would be the anode. A 1/10 ounce, or less piece of gold would do very well since it can be beaten very thin, to be the anode. A Gold Chloride, or other gold based electrolyte would be the medium of transfer.

The whole process include four parts: Physical crushing and separation equipment ; Serface gold deplating plant; Copper electrolysis production process; Gold refining machine line. Through years of practice and theoretical analysis, we obtain the best separation result, the separating purity can be reached to 99%.
How to Refine Gold (with Pictures) wikiHow
Jul 19, 2019· Step 1, Place your gold jewelry, gold powder or nugget inside of a crucible. Most crucibles are made of graphite, which enables them to withstand the melting of the material inside.[1]Step 2, Place the crucible on a fireproof 3, Aim an acetylene torch at the gold. Aim the flame at the gold until the gold is completely melted.[2]
What is Electrowinning?
Jul 10, 2019· The electrolysis process used in electrowinning allows the elemental metal to be recovered. This sets electrowinning apart from other recovery technologies, such as evaporation and ion exchange, which result in little more than a more concentrated metalbearing solution.
Electroplating Tutorial: General Processing Steps In ...
General Processing Steps Explanation Of The Strike Electroplating Process. A strike is an optional preliminary electroplating step that puts a thin but highly adherent layer on. Typically, a strike is run: at lower metal concentrations, higher current densities, and with few or no special additives.
How to Refine Gold: 2 Major Techniques of Gold Refining ...
Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many largescale goldrefining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast gold ingot at 95% plus purity is used as the anode.
Electrowinning and Smelting Resource Book
The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).

Electrolysis — the process In an electrochemical cell or galvanic cell, a spontaneous chemical reaction produces an electric current. In an electrolytic cell, the reverse process takes place. The passage of an electric current through an electrolytic solution causes a .
Electrowinning Wikipedia
The most common electrowon metals are lead, copper, gold, silver, zinc, aluminium, chromium, cobalt, manganese, and the rareearth and alkali metals. For aluminium, this is .
Copper Mining and Processing: Processing of Copper Ores ...
B. Processing of Sulfide Ore Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.
Silver Refining Process Outotec
Silver electrolysis tankhouse. The slime is collected inside anode bags surrounding silver Doré anodes and can be further processed using the Outotec Gold Refining process for recovery of gold and PGMs. Spent electrolyte withdrawn from circulation is replaced with fresh silver nitrate electrolyte in order to keep the silver content at a constant level.

Extraction of Gold Element Gold, Au, Transition Metal
The smelting process consists in the formation of an alloy of gold with silver and lead, and is similar to that employed in extracting silver. It is applicable to ores rich in silver, and also to refractory ores containing arsenic and antimony, for which the other processes are unsuitable.
