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.

Bauxite in Jamaica Geo for CXC

Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world. The mining areas are located in the western and central parts of the island. After mining, most of the bauxite is carried to alumina plants where it is refined into alumina.

Mining and Refining Process

Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post mining revegetation of the site. Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively
