Study Notes
Rig Control and Mining Technology
- Rig Control System (RCS) enhances precision and efficiency, removing operators from mine-related risks.
- Diesel Particulate Matter (DPM) consists of unused fuel, soot, and aldehydes present in the air of mining environments.
- Advantages of Battery Electric Equipment include reduced heat load and improved safety for mine workers, resulting in lower operating costs through diminished ventilation needs.
Heat Generation Comparison
- All Diesel fleet generates 2,962 KW of heat.
- Mixed Diesel (combination of electric and diesel) generates 2,301 KW of heat.
- All Battery fleet produces the least heat at 1,380 KW.
Key Questions and Answers
- Technology used to minimize heat load in underground mine equipment: Battery Technology.
- China is the world's largest producer of Rare Earth Elements (REEs).
- Essential mineral resources prone to supply disruptions include Rare Earth and Critical Minerals.
- Beryllium is a Critical Mineral due to its strength, high melting point, and ability to prevent metal fatigue.
- Lithium is critical as a commodity for powering electronics through batteries.
- The tailings dam failure in January 2019, which resulted in 248 deaths, occurred in Brazil.
Ground Control Innovations
- webGround Control offers an online platform for accessing NIOSH ground control design software, enabling on-demand calculations and enhanced collaboration.
- The U.S. initiated the Energy Resource Governance Initiative (ERGI) to reduce dependence on China for critical minerals, with countries like Australia, Botswana, and Brazil participating.
- The initiative focuses on sharing mining expertise to develop minerals including Lithium, Copper, and Cobalt.
Demand and Extraction Techniques
- Global cobalt demand has surged due to the rise of electric vehicles (EVs).
- Ammonia salts are utilized for selective copper extraction from tailings, with ammonium carbonate and ammonium persulfate leading to high recovery rates.
Mineral Requirements for Electric Vehicle Batteries
- Key components needed in EV battery manufacturing include Lithium, Cobalt, Nickel, and others.
- Among these, Nickel is identified as the highest requirement, with specific demands: Lithium (16 kt), Cobalt (1.5 kt), Nickel (17.5 kt), Graphite (25 kt), and Manganese.
Mining Machinery and Byproducts
- A developed machine mitigates abandoned mine tunnels using LHD (Load Haul Dump).
- Byproducts of coal combustion can be replaced by magnetic separation techniques yielding Fe3O4.
HydroFloat Separator and Mineral Extraction
- The HydroFloat Separator has two operational outputs:
- Overflow Coarse Mineral: Recovers nearly all particles with over 1% hydrophobic surface expression.
- Underflow Coarse Mineral: Rejects particles lacking hydrophobic properties.
- Au and Ag extraction globally employs various methods, including Gravity Concentration, Amalgamation, Cyanide Leaching, Roasting, and Zinc Precipitation.
