Modular DMS for early production29 Jun 2023 09:19
Atlantic Lithium has identified an opportunity to conduct early processing operations using a modular DMS processing plant and contract crushing services. The early production will precede the primary processing plant by nine months.
The pre-production flowsheet design criteria are as follows:
- 600,000tpa ore processed, with the DMS plant treating 375,000tpa after fines are removed; and
- The modular DMS plant will be operating at 80% utilisation for a feed rate of 50tph.
The contract crushing provider will crush ore to a top size of 10mm. The DMS feed material will be screened at 3mm to produce DMS feed (-10mm+3mm) and a fines stream (-3mm). The DMS plant will produce a spodumene concentrate, along with the deslimed fines as a secondary product for sale.
The DMS plant will be two-stage single size fraction process all using conventional DMS equipment. Grits and fines generated in the process will be thickened and filtered to produce a dry tailings which will be stockpiled along with the middlings.
The crushing contractor will provide an all-inclusive crushing service. The Modular DMS plant provider will supply experienced labour to commission and operate the processing plant for the first three months. A small team of Atlantic Lithium operations personnel will be recruited for operation of this plant to be trained and become familiar with DMS operation, and will later transition to the primary processing plant when the primary plant begins production.
