Start by reducing the size of gold to smaller. Melt gold, pour gold while melting through a 2 mm sieve into the water. Reducing the size of gold to smaller Will help in the process of aqua regia to make gold into the solution more quickly. aqua regia is composed of 2 chemical substances, 1 nitric acid, 3 hydrochloric acid mixed together.
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well ...

A series of free IGCSE Chemistry Activities and Experiments (Cambridge IGCSE Chemistry). Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements. Ores are rocks containing enough metal to make it economical to extract.
Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution. Concentration of the copper(II) sulfate solution by solvent extraction.
