San Xavier Mine West Portal Expansion

Project number
24075
Organization
San Xavier Mining Laboratory
Academic year
2023-2024
The San Xavier Mine in Sahuarita, Arizona, requires a new portal expansion to the underground 150-ft level (vertical) at a maximum decline grade of 15%. The project sponsor requests a multistep process to decide the portal expansion's location and structure. A 70,000 square meter area will be surveyed using magnetics and resistivity data to determine the optimal location and structure of the new portal and decline. Following the interpretation of the collected geophysical data, the sponsor requests the team determine the design for the potential portal expansion on the Western side of the San Xavier Mine.

Laser Diode Based Metrology Module

Project number
24073
Organization
ASML US, Inc.
Academic year
2023-2024
Project description:
Design, build, and bench test a compact laser diode based metrology module that can illuminate a stream of water droplets and record the reflected signal from each droplet (or group of droplets) over a given time interval using a suitable solid state detector.
Background:
ASML in Rancho Bernardo, CA develops EUV (Extreme Ultra Violet, 13.6 nm radiation) lithography light sources for EUV lithography tools using LPP (Laser Produced Plasma) technology. EUV generation takes place inside a large diameter (>1.5 m) chamber by vaporizing/ionizing small liquid Sn (Tin) droplets at high repetition rates (50 kHz) using a powerful CO2 laser. The vaporized/ionized Sn droplets produce EUV radiation which is collected by a mirror and focused into a lithographic scanner. The scanning system exposes lithographic patterns on semiconductor wafers using the EUV light.
During EUV source operation, the Sn droplet stream passes through a light curtain (for example, a light curtain produced by a laser beam). The reflected light from the curtain is collected by a solid state detector whose signal is used to fire a powerful CO2 laser at the “proper time” to vaporize/ionize each Sn particle in the stream – thus producing EUV light.
Problem and Capstone Statement (using water droplets):
The detection of Sn particles and their position in space at a given time is critical to the operation of the LPP EUV source system. It is desirable to produce a metrology system using a diode laser and solid state detector that can be used to identify the position of small (~1 mm) moving targets - water droplets - in such a way that the light signals can be used to control the output of an external light source (an LED for example) which could in principal be used to fire an external laser or device.
The project task is to take this design and build a prototype using commercial off the shelf parts, supplemented by 3D printed or locally machined parts to deliver a unit that could be tested on a UoA test bench. The approximate size of the system (metrology unit) consisting of the water droplet dispenser, laser diode, and detector should fit inside a cube of no more than 2ft on each side – additional circuitry for collecting and displaying outputs need not be included in the contained metrology unit. Details of the firing sequence, and other details will be explored by the team during conversations with ASML leads.

UA Department of Biomedical Engineering
Academic year
2023-2024
Design, fabrication and validation testing of a platform, servo motor device, and the software to collect 3D scans of the stiffness of the ligaments supporting the arch of the foot using ultrasound shear wave elastography. The platform will accommodate feet of various sizes and patients with variable difficulty with prolonged standing. The servo device will hold the ultrasound probe and scan the foot at a user selected speed. The ultrasound data will be post-processed to create a 3D model of the stiffness of the arch supporting ligaments.

Automated Material Sampling

Project number
24070
Organization
FLSmidth Krebs
Academic year
2023-2024
In mining, it has been difficult to consistently and repeatedly sample slurry discharged from cyclones in a manifold system. It is currently a manual process that varies in accuracy because of the accessibility to the sampling source and the variation of samples taken due to the human element involved. In the same way being that it is a human process, it is difficult for an individual to connect a heavy armature to the side of the launder to take a sample without the risk of the individual being pulled into the tank. The same sampling problem also becomes a safety issue that could be resolved by automating the sampling process.   To properly automate the process the cutter box or the collector for the liquid, needs to pass underneath the spray evenly and at an even speed. Depending on the box shape, the box needs to pass radially or parallel through the discharge stream to collect the proper sample.   In summary we are looking to find a way to automate the sampling collection process to make it safer and more accurate. The automated solution will make it possible to conveniently sample any of our cyclone systems from a control room.

Leach Pad Cover Wind Mitigation Proposal

Project number
24069
Organization
Freeport McMoRan
Academic year
2023-2024
Project Scope: Freeport-McMoRan Inc, (Freeport) is a leading responsible copper producer – supplying 9% of the world’s mined copper. Copper is at the heart of the energy transition because it is the metal of electrification. Technologies critical to the energy transition such as EVs, charging infrastructure, solar photovoltaics, wind, and batteries all require much more copper than conventional fossil-based counterparts. Analysts forecast that supply must double by 2035 to supply enough copper to support the global decarbonization initiatives and objectives. However, bringing on new copper supply is challenging, which may delay the energy transition. Freeport is committed to responsibly meeting growing demand through our sustainability strategy. Our Leach to the Last Drop Initiative (L2LD) involves advancing technologies and strategies to generate incremental and less carbon intensive copper production from ore on our leach pads that has historically been defined as waste. Leaching generally has a lower carbon footprint, is less capital intensive, and uses less than 50% of the water versus processing copper through a concentrator.
One component of our L2LD initiative involves covering leach stockpiles with a thin urethane sheet that is proven to increase copper recovery through heat retention and reducing water consumption due to evaporation. Covers are installed manually on the leaching stockpiles and then manually weighed down by operators using rocks to prevent them from blowing away. This manual process takes time, is human resources intensive, and has the potential to increase hazard exposure to our employees. Safety is a core company value and is foundational to our sustainability approach. Over the past several years we have partnered and designed automated cover deployers that can deploy the plastic onto the piles; however, the wind presents another challenge in keeping the covers securely on the pile to allow them to generate heat.
