Overview
This case presents laboratory test results for a feldspar sample at 60 mesh, submitted by FOSHAN POWTECH / PTMS. Sample A is the feed before iron removal, and Sample B is the material after iron removal. The analyses were carried out by an independent third-party laboratory, and the laboratory test was reported in 2025.
The original report does not specify the equipment or process conditions.

| Na₂O | 9.22% | 9.59% |
| TiO₂ | 0.46% | 0.31% |
Notes on the results
The original laboratory report states a particle size of 60 mesh, but does not specify whether the test was dry or wet, or the magnetic-separation conditions. 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.
