AI Technical Summary
Technical Problem
In existing tin ore powder production processes, it is difficult to further improve the purity of the finished product, and the loss of ore powder is relatively large.
Method used
Through steps such as material pretreatment, screening, magnetic adsorption to remove impurities, wind-powered powder collection, washing and grinding, impurities are separated and removed to ensure high purity and low loss of tin ore powder.
Benefits of technology
This achieves high purity and low loss of tin ore powder, improving the quality and stability of the finished product.

Abstract
The application discloses a production process of tin ore powder, and specifically comprises the following steps: S1, material pretreatment, selecting tin ore raw ore and cleaning the same to remove surface stains; S2, material primary treatment, crushing the treated raw ore and screening the same to obtain oversize and undersize. The application separates the oversize and undersize after preliminary crushing and screening of the raw ore, removes magnetic impurities in the oversize and undersize through magnetic separation, collects powder in the undersize, prevents loss of the ore powder in the cleaning process, further reduces the particle size of the crushed ore through secondary crushing, and finally, synchronously feeds the cleaned crushed ore and the collected ore powder into a grinding device for grinding, so that the finished product is obtained, the loss of the ore powder is small in the process, and the purity of the tin ore powder finished product is ensured.
