Overview
This case presents laboratory chemical analyses of a quartz-sand raw sample and a quartz-sand finished product, tested for FOSHAN POWTECH / PTMS and reported in 2026. Those two labels are taken from the original reports.
The two reports cite different test methods: GB/T 4734-2022 for the raw sample and JC/T 753-2022 for the finished product. The figures should be read with that difference in mind. The original reports do not state whether the material was processed dry or wet, or the equipment or process conditions. Values are shown exactly as reported. Titanium dioxide (TiO₂) is listed only because it appears in the original analyses; this page does not claim a reduction in titanium. No removal percentage is stated or calculated.
Test results
Each submitted sample was a powder, about 160 g. Laboratory records, 2026.

Notes on the results
The results are for reference only and are subject to a laboratory test on the customer's own sample. Laboratory test results are not a guarantee of industrial-plant performance. Customers are welcome to send 5–10 kg for a free laboratory test; a report is issued within 5 days of sample receipt.
A desensitized English transcription of these results tables is available as a PDF. It is not the original issued report.
