Which method is used to mine diatomite?
open pit methods
Most diatomite deposits are found at or near the earth’s surface and can be mined by open pit methods or quarrying.

How does TauTona Gold Mine in South Africa work?
TauTona shares a processing plant with Savuka. The plant uses conventional milling to crush the ore and a CIP (carbon in the plant) to further treat the ore. Once the carbon has been added to the ore, it is transported to the plant at Mponeng for electro-winning, smelting and the final recovery of the gold.
