in this instructable, i will show you how to extract gold from computers using products most people have lying around in their homes. the way i extract the gold is relatively strht-forward and pretty easy, but the chemicals used are very dangerous and should not be performed without proper knowledge and equipment. this process is not supposed to be lucrative.
excluding mechanical, smelting, and amalgamation processes, the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods. in these
gold refining. this refers to processes used to processes used to extract and separate the precious metals in mined material, doré, and from recycled products jewellery and electronics . the main techniques used to remove the final impurities to create high caratage gold are summarised below:
the common processes for recovery of gold solution includes: i carbon adsorption, merrill-crowe process, iii electrowinning and iv ion-exchange / solvent extraction. traditionally, merrill-crowe process was used to remove gold from a cyanide solution by using zinc dust to precipitate gold from its solution.
information on how to extract gold from rock, extracting gold from rock but it was definitely gold. i don't know how efficient the process was, but we probably got a couple of grams of gold from several large sacks of our gold-bearing rock. and all it took was a lot of crushing and a bit of chemistry wizardry.
the first gold using a process without cyanide and without mercury has been produced using technology from csiro minerals technology www.csiro.au at a demonstration plant in the western australian goldfields town of menzies. cyanide is used in more than 90% of global gold production, but producers
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.
the process in extracting gold is done in steps. one the ore of gold is found and treated it is crushed to heap leaching and then is sent off for grinding, concentration, and roasting and pressure
