From here, a decision whether to mine or not can be made. Step 2: Mining PIPE MINING - PRIMARY DEPOSITS. There are two types of pipe mining, namely open-pit mining and underground mining. Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. Once exposed, the ore in the pit is broken up by blasting.
The ore from the underground mine will be crushed in a conventional two-stage crushing circuit and grinded in a ball mill before passing through elution and electro-winning circuits for gold extraction.
