What is Gold? Jewelry Info Place
The varying percentage of copper used determines the color of the gold. The more copper that is used, the stronger the rose color. Pink gold uses the least amount of copper, followed by rose gold, and red gold has the highest copper content. There is no such thing as pure rose gold, since rose gold is an alloy of gold and copper.

The Mining Process – Waihi Gold
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
