Lead - Essential Chemical Industry

The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore. Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away.

Metals 101: Properties of Metal, Experiments, and More

The resulting reactions separate out the iron from the oxygen in the ore. This 'pig iron' needs to be further mixed to create wrought iron. It can also be used for another important purpose: when heated with carbon and other elements, it becomes a stronger metal called steel .

How to separate different metals - Gold Refining

Apr 10, 2012· The smaller the amount of copper used, the slower will be the reaction---so if you have only a little, expect it to take days. I would recommend you avoid cementing the copper unless you have no other options. The advice to get all crystallized materials back in solution is dead on.
