From Ore to Finished Product
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Extracting Gold
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

How is Silver Refined?
— Cupellation aims to separate base metals from noble metals. It is the process of treating ores and alloys under extremely hot temperatures to separate noble metals like silver from base metals like lead and zinc. Cupellation takes advantage of the fact that noble metals do not oxidize or react chemically, like base metals.
How to Separate Gold From Other Metals at Home?
How can you separate gold from other metals? The most common method used to separate gold from other metals is by using a panning technique. Panning mainly involves swishing water and sediment around in a pan in order to separate the heavier gold particles from lighter ones. This process works best with small pieces of gold, such as flakes or dust.
Gold Extraction & Recovery Processes
— The pregnant solution can be treated by activated carbon or zinc powder (Merryl Crowe process). The second is applied in many operations, but the final decision is based on the silver/gold ratio and economical considerations. Activated carbon does not recover much of the silver, but the gold recovery is high.
How to separate silver from gold ore>
— was351, Depending on gold to silver ratio content of the metal, the silver in aqua regia can make it hard to dissolve the gold as the silver chloride forms a crust keeping the acids from dissolving the gold, and then also the gold can make it hard for nitric acid to get at the silver to remove the silver copper from the gold. In your gold the ...
