Commissioning software for lithium plants where a DMS circuit, a concentrator and a hydroxide conversion train each run to a different chemistry.

A spodumene concentrator's crushing, screening, dense media separation and flotation circuits are commissioned wet, cell by cell, chasing a lithium recovery curve that depends on ore variability from day one of ramp-up.

A downstream lithium hydroxide or carbonate conversion train — roasting kilns, acid leach, impurity removal, crystallisers and dryers — is commissioned against a chemical process specification with its own reagent handling, corrosion-resistant materials and product purity gates, often years or phases apart from the concentrator.

Deskely tags the concentrator circuits and the conversion train as separate process areas with their own commissioning sequences, so a construction and process team is not forced to report both on one generic 'plant commissioning' percentage that hides which chemistry is actually behind schedule.

Concentrator wet commissioning runs ore through the DMS and flotation circuits with lithium recovery, concentrate grade and moisture logged per shift against the tag, so a metallurgist can see whether a shortfall traces to crusher throughput, DMS media density or flotation reagent dosing.

Conversion train commissioning introduces reagents in a controlled sequence, with hazardous chemical handling checks, PPE and interlock verification captured before roasting or leaching begins, and product purity samples logged against each crystalliser batch.

Vendor punch lists from the concentrator OEM and the conversion process licensor are tracked separately, since a concentrator mechanical defect should not block conversion train ramp-up and vice versa.

Battery-grade lithium hydroxide and carbonate offtake agreements specify tight limits on trace impurities — iron, calcium, magnesium, sodium and sulphate — well beyond the headline lithium content, and a crystalliser or centrifuge batch that looks compliant on the primary assay can still be rejected by a cathode manufacturer's incoming QC on a single trace element.

Because the impurity limits are often tighter than anything the concentrator or conversion plant's own process control philosophy was originally designed around, first-batch product certification tends to expose gaps between what the plant's instrumentation actually measures and what the offtake contract requires as certified evidence.

Deskely records each conversion train batch's full impurity panel against its crystalliser or centrifuge tag, alongside the sampling and lab chain-of-custody record, so a product certification pack for the offtaker is assembled from the same register as the mechanical commissioning evidence rather than reconciled separately by the marketing team against a lab spreadsheet.
