Pure 24 karat gold is a soft, malleable metal. In jewelry manufacturing, it is usually alloyed with other elements such as silver and copper to increase its hardness and to improve its wear resistance. Gold jewelry is stamped with a karat rating to define the amount of pure gold contained within its

TOMRA Sorting Solutions utilizes cuttingedge copper sorting technology to get results from copper mined sulphide and oxide deposits. Our copper sorting technology treats feeds from both types of ores based on different physical properties at feed rates of up to 300t/h.
When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

#0183;#32;In order for the higharsenic regions of the Northparkes coppergold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of higharsenic drill cores from Northparkes it was possible to selectively separate tennantite
Gold parting is the separating of gold from and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called the advent of coinage, methods had to be invented to
