Mining and Refining – Process

Before mining can commence the land needs to be cleared of timber and vegetation. 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. Next the top soil is removed and is usually also stored for replacement during rehabilitation.

Gold Mining and Processing: Everything you Need to

Once mining engineers know where gold is located and what other materials surround it, the mining process can begin. If the gold is located close to the surface, it’s mined with open-pit mining techniques. Gold that’s located farther below the surface is collected with underground mining methods.

Zinc Mining and Processing: Everything you Need to

Compared to tin mining, the history of zinc mining is relatively short. In the 18th century, it was discovered that sphalerite, or zinc sulfide, could be smelted into brass, resulting in the first patented techniques. Since then, the zinc industry has progressed to the current zinc mining process and production methods
