Key Parameter Comparison
| Product Model | Particle Size (mesh) | Magnetic Content | Density (g/cm³) | Dielectric Loss Tangent | Suitable Ore Types | Separation Accuracy |
|----------|------------|----------- -|---------------|------------|----------|----------|
| Jinshuo 65D | 60-80 | ≥99.2% | 7.0-7.1 | ≤0.8% | Coal Beneficiation (Coarse-grained) | Concentrate grade increase of 2.1% |
| Jinshuo 100D | 90-110 | ≥99.3% | 6.9-7.0 | ≤0.9% | Phosphate ore (Medium-grained) | Concentrate grade increase of 2.3% |
| Jinshuo 150D | 140–160 | ≥99.5% | 6.8–6.9 | ≤1.0% | Fluorite / Iron Ore | Concentrate grade increase of 2.5% |
| Jinshuo 270D | 260–280 | ≥99.6% | 6.7–6.8 | ≤1.1% | Lithium ore (fine-grained) | Concentrate grade increase: 2.8% |
Note: Data sourced from Jinshuo laboratory test reports; actual loss rates in practical applications may vary by ±0.1% depending on the beneficiation process.
High Magnetic Properties: Magnetic content ≥99%, far exceeding the industry average of 95%, resulting in a 15% increase in magnetic separation recovery efficiency and reduced media loss;
Low Wear: Utilizes a “medium-frequency melting + air classification” process, producing particles with smooth surfaces and uniform magnetism. Media wear rate is controlled within 1.1%, resulting in annual savings of approximately 80,000–120,000 RMB (calculated based on a daily consumption of 1 ton of media);
Uniform particle size: Particle distribution is controlled using a laser particle size analyzer, with a size deviation of ≤5% for the same model, ensuring stable slurry density and preventing stratification during the separation process;
Stable composition: Silicon (Si) content is strictly controlled within the 14–18% range to prevent reduced magnetism caused by excessively high silicon content or compromised particle strength due to excessively low silicon content.
In heavy-medium mineral processing, parameters such as the particle size, magnetic content, and density of ferrosilicon powder directly determine the stability of the suspension and the accuracy of separation—coarse-grain mineral separation requires consideration of settling velocity, while fine-grain mineral separation demands uniform dispersion of the medium; selecting the wrong grade may result in a 3%–5% decrease in concentrate grade. As a manufacturer specializing in heavy-medium ferrosilicon powder, Jinshuo has developed four major product series—65D, 100D, 150D, and 270D—tailored for different mineral types such as coal, lithium ore, phosphate ore, and fluorite. We strictly control core composition at Si 14–18% and Fe 80–83%, with magnetic content consistently maintained at over 99%. This article will analyze the compatibility logic of Jinshuo’s products from a technical parameter perspective to help mineral processing enterprises make precise selections and avoid blind procurement.
