the gold should slip down into the smelting vessel. after this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well. its common at this point to refine the gold through a separate refinement process to ensure a high level of purity
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
2 gold electrolysis is the second, popularly used method in gold-making industries to separate gold from the other metals. this procedure has been noted to produce gold that is almost 99.999 pure. it involves setting up an electrolytic equipment, which consists of two separate nodespoles known as anode and cathode

shawn - pure gold is not magnetic. that is, it doesnt form a magnet on its own. if you put it in a magnetic field it will magnetize a tiny bit, but only so long as its in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. there are alloys of gold, for example gold with more than about 20 of the atoms replaced by iron, which do magnetize on their own, at
