Canadian Premium Sand (CPS) has completed a test simulation of the industrial-scale processes required to refine specific sand for solar glass manufacturing.

The test, conducted by Hazen Research, simulated the industrial scale processes required to produce solar glass specification sand as the primary feedstock for the company’s patterned solar glass manufacturing facility being developed in Selkirk, Manitoba.

The testing verified that the requirement for simple mechanical treatment processes including only basic attrition scrubbing and gravity and magnetic separation.

It confirmed a low-cost and environmentally responsible process methodology can be employed to produce solar glass grade silica sand without the use of iron reducing chemicals.

It finalises the pre-construction engineering and design of the company’s sand processing facility.

CEO and President Glenn Leroux said: “With these sand testing results in hand, we have completed an important milestone in the development of our integrated solar glass manufacturing project.

"We have now confirmed the industrial scale processes required to refine our silica sand to solar glass grade enabling us to finalise details of our sand processing design and equipment selection.

“We remain on track to bring our solar glass manufacturing project to shovel-ready status by the end of Q1 2023.”

CPS had previously announced glass technology group HFT as its EPC contractor to conduct pre-construction design and engineering for its new production facility.
