We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals. We need to separate the gold from everything else in the rock so the rock needs to be treated in some way. In New Zealand we chiselled some rocks from an outcrop near a small creek.
It is profitable to process a ton of rock to get at five grams of gold; rock with that much gold is "gold ore". Copper bearing rock must have 1% copper to be considered "low grade ore" that ton of ore would yeild twenty pounds of copper.
Get smarter about recycling and refining Gold, Silver, Platinum, Palladium, Rhodium and Electronics scrap. Find tips and strategies to reclaim hidden profits from your precious metal scrap.
The Metal Recycling Process. The metal recycling process is similar to the usual recycling process. The metals are first sorted on the basis or their properties. It is however important to have the basic understanding or knowledge about metals.
Prof Eksteen says in sufficiently warm underground environments the process would be applicable to solution mining, where solvents are injected into an ore body and recovered along with the gold ...
Electronics contain valuable precious metals such as gold, silver, platinum, palladium, copper, tin, and zinc that can be recovered and used to make jewelry, plating, new electronics, or automotive parts.
USbased mobile recycler PaceButler said that more gold can be recovered from one ton of mobile phones than from 17 tons of gold ore. Mobile phones also yield useful materials such as platinum, palladium and copper, as well as plastic and glass.
This process, called cyanide milling, is fairly efficient recovering 95% to 98% of gold from the ore. It can be done economically using ore with less than one gram of gold per ton (depending, of ...
Step. Start by obtaining as many scrap electronics components to reclaim gold from. Generally speaking, older electronics work better because enhanced manufacturing processes use less gold than older electronics, so an old 386 or 486 computer, for example, contains more gold .
May 13, 2010· This invention is related to a process for extracting gold from goldbearing ore. BACKGROUND OF THE INVENTION Various leaching processes are known for extracting precious metals (, gold, platinum, silver) from various minerals.

It is possible to remove the gold from the main stream by solvent extraction too (HEV CHEMICALS is supplying extractants for this process) but it is not recommended in the pgm ore concentrate refining cycle because the amount of gold is quite low; hence this process would be rather costineffective.
The process mineralogy of gold is not limited to the gold minerals, submicroscopic gold, and their carriers but also includes the study of gangue minerals and other species that may affect gold processing, such as cyanicides.
