Currently, most mining companies conduct chemical analyses by X-ray fluorescence performed in the laboratory to evaluate quality of Fe ore, where focus is mainly on content and presence impurities. However, this type analysis requires investment time money, results are often available only after ore has already been sent processing plant. Reflectance spectroscopy an alternative method that can ...

The article presents the results of a comparative analysis of the metal substructure for dental prosthesis made from a Co-Cr-Mo-W alloy by two techniques, i.e. precision investment casting and selective laser melting (SLM). It was found that the roughness of the raw surface of the SLM sinter is higher than the roughness of the cast surface, which is compensated by the process of blast cleaning ...

The fuel segregation distribution sintering process, with a high dosage in upper layer and low bottom of the bed, was studied to handle uneven heat problems conventional iron ore process. A mathematical simulation method adopted contrastively study process accuracy model verified through experiments. In addition, different heights beds were discussed assess technology. contrast temperature evol...

The New Zealand sea sand ore is a kind of vanadia–titania magnetite formed by erosion in the coastal zone. Because its coarse particle size, smooth spherical particles, complex chemical composition, it has been added to sinter as an auxiliary material. Based on principle optimizing blending strengthen advantages and weaken disadvantages, this paper used raw that not undergone any pretreatment m...

The mixing effect of powder materials is crucial in the iron ore granulation process, which determines composition and particle size distribution, thereby affecting quality sinter. To study particles a high speed shear mixer (HSSM) cylinder (CM), numerical simulation based on discrete element method was adopted this work. For CM, movement consists slipping slumping. HSSM, rolling cascading. int...
