Mineral Processing Lab
Machine-translated · View original
A lab that tackles challenges in resources, materials, and the environment with separation and thermal technologies.
AboutAbout the lab
Contributing to resources, materials, and the environment
The Mineral Processing Lab works on a wide range of problems related to resources, materials, and the environment.
It aims to make the development of environmentally friendly materials, and the process technologies for refining and recycling resources, more advanced and more efficient.
Its research includes flow and heat during the cooling of hot metal, observation of the pores in rock, and applying resource separation technologies to environmental remediation and recycling.
The lab belongs to the Department of Applied Energy Science in the Graduate School of Energy Science, and also accepts students from the Resources Engineering Course of the Department of Global Engineering.
Key terms
- Multiphase flow
- A state in which multiple fluids with different properties, such as a liquid and a gas, flow mixed together in the same space
- Flotation
- A method of separating particular particles from others by attaching them to fine bubbles so that they float
- Unconventional hydrocarbon resources
- Oil and natural gas resources, like shale gas, found in rock different from that of ordinary oil and gas fields
ResearchResearch themes
To help humanity continue to live safely, the lab works on developing materials that are friendly to the global environment and on making the process technologies for refining and recycling resources more advanced and more efficient.
*Illustrative imageFlow and Heat When Cooling Hot Metal
When metal is rapidly cooled by heat treatment, water boils and forms a multiphase flow in which liquid, vapor, and air mix. The lab observes the flow when a liquid hits a hot solid, and clarifies the mechanism through the development of heat measurement methods, experiments, and 3D simulation.
*Illustrative imageExploring Resources by Observing Pores in Rock
The lab develops methods for observing tiny pores and fractures inside rock. It uses them to evaluate rock that stores unconventional hydrocarbon resources such as shale gas, and to analyze the process by which rock fails.
*Illustrative imageApplying Separation Technology to the Environment and Recycling
The lab applies energy-saving separation technologies developed in the resources field to soil decontamination and wastewater purification. It studies the mechanisms and applications of new separation technologies, such as flotation using microbubbles.
