Title: Sulphur Mining
IPC: E21C41/16
Filed: 1978-11-21
Abstract: A bitumen-containing sulphur deposit is mined by first sealing off a reservoir in the deposit by sinking boreholes in a closely-spaced row along the periphery of the region to be sealed, exploding charges in the boreholes and filling the caverns so created with waterproof sealing material. The sulphur in the reservoir is then melted and adsorbents such as diatomites or clay earth in water suspension are injected. The molten sulphur is pumped up and treated with sulphuric acid injected into the pipelines to oxidise residual bitumen, after which the molten sulphur may again be treated with adsorbents and is then filtered.
