The cathode is made of a piece of pure metal. During electrolysis, the gold in the raw rock material is not dissolved and collects as a sludge under the anode. Together with gold other precious metals (f.e. Silver, copper, lead, tin) concentrate in this anode-sludge and can be easily skimmed off.

Because gold is a relatively soft metal, it's usually mixed with quantities of silver and other various common metals such as copper to give it more of a hardness. 24 carat gold is almost pure gold 18 carat gold is approximately 75% gold and 25% other less valuable metals 9 carat gold is approximately 37% gold and 63% other less valuable metals.
Watch the gold separate. After the slag has been heated for long enough, the molten gold begins to dissolve away. Allow the gold to slip down into the smelting vessel. After this has occurred, wait for the gold to cool, remove it from the smelting vessel and remove the slag.
