Four-stage crushing process

As per a design flow sheet, a four-stage crushing process is planned to produce crushed ore of 0.85-6mm size.

The process will result in spodumene planned to be filtered and blended with the final spodumene concentrate.

Later, two streams will be created from the material recovered either of <3mm or >3mm. The two streams will be directed through two-stage dense media separation units. The spodumene recovered from both streams will be blended together and stored. The plant will be winterized to allow proper functionality in the Québec climate.

The design of the plant includes a flotation unit, which will make the plant more resilient to process different ore types from the James Bay, Québec region, improving its capacity for a variety of ore types and adding strength in operations.

As of now, Primero has prepared Process Flow Diagrams (PFD) along with a Block Flow Diagram (BFD). Also, a Mass Balance as well as a Process Design Criteria (PDC) has been delivered.

Now, the work has been started on the Piping and Instrumentation Diagrams (P&IDs) to develop a layout of instrumentation, equipment, process streams, and control logic.

Concurrently, Primero has kick started producing datasheets using data obtained from the Mass Balance and PDC.
