Can silver ever be ethical?

Generally, silver comes to market as a byproduct of the industrial mining of other metals, such as copper, zinc and gold. In 2005, only 30 per cent of silver came from actual silver mines. It is no high honour to be grouped into 'one of the world's most destructive industries', as the industrial mining industry is known.

Mining And Mineral Processing

Once a suitably sized deposit of a mineral has been found, mining can begin. In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand. Mining is largely divided into surface and underground mining. Minerals are often found in river beds, beach sands and other sandy areas.

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.

Processes

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).
