Debswana Diamond Company (Pty) Ltd.

Letlhakane Mine Tailings Resource Treatment Project

In sub-Saharan Africa, Fluor has applied its modular approach to design 60 process plant modules and 106 conveyor and services gantry modules for Debswana’s Letlhakane Mine Tailings Resource Treatment Project (LMTRTP) in Botswana.

The design of the modules was tailored specifically around the project size, location and client requirement. They were assembled locally at a yard off site and transported to the mine by road.

Fluor was awarded the engineering phase of the LMTRTP in 2014. The new 2 Mt/a plant will recover the existing coarse diamond tailings mineral resource and extend the life-of-mine of the Letlhakane operation by 20 years.

The design of this stand-alone plant is centered on a modular approach. The main process areas such as the Dense-Media Separation (DMS), scrubbing and crushing buildings have been designed in such a manner as to allow them to be fully constructed from fit-for-purpose modules, thereby accelerating project execution.

Fluor completed construction for the LMTRTP in November 2017.
