Opis:
Crushing plants are of great interest in reducing a particle size of rocks and ores as milling operations need to consider sustainable development. Since the crushing plants operate under harsh conditions and involve very abrasive material, multiple factors can influence their performance. This paper assesses a number of factors affecting the performance of the crushing plant by addressing the critical design parameters and consideration of ore characteristics, operability and maintainability. Due to the fact that ore properties remain the same during milling, its control may become difficult for yield and quality of a product. However, an operation factor can contribute positively to the performance if it is well managed by experienced operators. The present paper also considers the operational, instrumental, mechanical and maintenance aspects of crushing plant, focusing on the capacity and quality.

Opis:
Svanbergite in Sichuan Province, China is a special middle-low grade phosphorus ore. It contains rare earth elements (REEs), aluminum, and strontium that can be exploited and utilized. In this study, several methods were used to systematically study the occurrence of REEs in the ore and basic ore characteristics. The ore, which was rich in REEs, Al, and Sr, was classified as marine sedimentary low-grade phosphorus ore. The main ore mineral was crandallite and pyrite, and independent REE minerals were not found. Crandallite was the main carrier mineral of useful elements, including P, REEs, Al, and Sr. REE+ was inferred to mainly exist in crandallite via isomorphism by replacing Ca2+ and H+. The crandallite was mainly characterized as fine-grained, and minerals were closely disseminated. The results from this study will provide a valuable reference for expanding available REE resources and the efficient comprehensive utilization of svanbergite.
