MORPHOMETRY OF ELECTRUM FROM LAYERLIKE . Key words: electrum, morphometry, Khan Krum, Ada tepe, Bulgaria Introduction. The shape and morphometric characteristics of gold and electrum represent important technological properties that determine the methods of their recovery during ore processing and the methods of gold and silver metals extraction.

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.
Electrum was a naturally occurring silver gold alloy with half the value of pure gold: 1 electrum piece (ep) was worth worth 50 copper pieces (cp), 5 silver pieces (sp), 1/2 of a gold piece (gp), or 1/20 of a platinum piece (pp). A standard electrum coin was approximately mm in diameter and weighed approximately 9 grams apiece (or 50 to one pound). As a bulk trade good, it was worth 25 ...
In the United States, one area where electrum is commonly found in in the state of Nevada, but it has been found in many other mining districts also. Even nuggets that are bright, shiny and have a rich golden color still have a small amount of impurities in them, and they are never pure. The purity of gold nuggets varies from statetostate.
electrum can lead to slower gold leach ing kinetics, ... The developments related with gold extraction from pregnant solutions include, carboninpulp, carbon inleach processes, the use of ...
Gold extraction Gold mining •Panning )لصفلا( – sand and gravel (ىصح) containing gold is shaken around with water in a pan. Gold is much denser than rock, so quickly settles to the bottom of the pan. 4 •Hard rock mining – used to extract gold encased in rock. Either open pit mining or underground mining.
Gold Extraction and, over 20% are called electrum The average concentration of gold in the world is about 0005 g/t which is lower than other metals The low concentration of gold in primary rocks means that upgrading by a factor of is usually.
The reactions that take place during the dissolution of gold in cyanide solutions under normal conditions have been fairly definitely established. Most agree that the overall cyanide equation for leaching and cyanidation of gold is as follows: 4 Au + 8 NaCN + O2 + 2 H20 = 4 NaAu(CN)2 + 4 NaOH
Mar 14, 2011· Electrum was the type of natural gold that was mined by the ancient Egyptians to the east of the Nile River from the desert between the river and the Red Sea. To the ancient Greeks it was known as gold or white gold that differentiated it from refined gold.
Electrum is a goldsilver alloy containing 20 to 45 percent silver. It varies from pale yellow to silver white in colour and is usually associated with silver sulfide mineral deposits. Gold also forms minerals with the element tellurium; the most common of these are calaverite (AuTe 2 ) and sylvanite (AuAgTe 4 ).
The LS ores have electrum ± gold as principal ore minerals, along with associated silver sulfides, selenides, tellurides, and sulfosalts, which generally occur with such gangue minerals as quartz, opal, adularia, and calcite (examples: Sleeper, Round Mountain, Midas, Nevada); (2) High sulfidation or "acidsulfate" ores that form from ...

Electrum: Gold and Silver Together. January 2016 by Chris Ralph...if you are out prospecting and find something that looks very much like a nugget but has an odd greenishgray cast to it, don''t be too quick to simply toss it aside as junk.
Electrum with a high silver content may give poor gold extraction due to tarnishing of the silver (Fleming, 1998). The presence of copper in the ore at above ±% concentration may make direct cyanidation uneconomic without retreating the Cu(CN)2 formed in leaching, through processes such as SART and Hannah.
