Increasing NET METAL PRODUCTION THROUGH GRIND CIRCUIT INNOVATION
Increasing the Throughput of the Global Copper Industry by as Much as 25%
Increasing the throughput of the global copper industry by as much as 25% to bridge the decade long 30% supply deficit being forecast
450 Mine Sites
We are a trusted partner and technology innovator to the global mining industry……. Just ask one of the 450 mine sites that has our equipment installed
46 Countries
Our commitment to serving our mining customers in more than 46 countries drives our continual focus on delivering highly innovative process optimization solutions
25% Throughput Improvement
We have earned the respect and trust of the mining industry with our process optimization solutions which can dramatically improve the throughput of an existing mining operation by up to 25%
WE ARE CiDRA
- We are a trusted partner and technology innovator to the global mining industry……. Just ask one of the 450 mine sites that has our equipment installed
- Our commitment to serving our mining customers in more than 46 countries drives our continual focus on delivering highly innovative process optimization solutions
- We have earned the respect and trust of the mining industry with our process optimization solutions, but are now rolling out to the mining industry a breakthrough approach to sulphide mineral based, coarse particle recovery that can dramatically improve the throughput of an existing mining operation by up to 25%
- This is particularly important to the global copper industry which is forecasting a 30% structural supply deficit over the next decade with very limited options in place to impact this deficit.
MACRO STATEMENT
Surge in Copper Demand
The green transition will support a surge in copper demand – Copper demand is estimated to grow nearly 600% to 5.4 Mt by 2030 across Electric Vehicles, wind, solar and battery technology
Under-invested Copper Market
The copper market is unprepared for this critical role – It is estimated that there will be a long -term supply gap of 8.2 Mt by 2030
Mid-decade Sticky Supply
Sticky supply threatens to deplete copper stocks by mid-decade – Copper is so integral to the green transition that supply requirements necessitate a spike in copper prices
Necessary Path
Copper is on a necessary path to $15,000/ton – Copper prices as of May 7th (10,424/t) are too low to prevent a near-term risk of inventory depletion
Key for Electrification
Copper is key for electrification – Copper properties make copper the first-best affordable material for the use in cables, batteries, transistors and inverters-all key technologies on the path to net zero
Supply Peaks in 2024
Copper mine supply peaks in 2024 – After a 5-year period of essentially no growth in copper mine supply up to and including 2021. it is expected that mine supply will peak in 2024 at 24Mt before declining in 2026 and through 2030
Advantages of the P29 Solution
Innovative Approach
P29 represents an innovative approach to unlocking the capacity of existing grinding circuits through the application of coarse particle recovery
- Grinding at a larger particle size can increase the throughput of an existing grinding circuit by up to 25%
Dramatically Improves Throughput
P29 dramatically improves the throughput and economics of an existing mine site without the cost of a new grind line
Bolt on Functionality
Bolt on functionality of P29 ensures compatibility with current chemical reagents in an efficient footprint
- Optimizes the existing flotation process for fine particle recovery and enables coarse particle recovery though the P29 process
Lowers Water Usage
The P29 system lowers water usage significantly as well as enabling power reduction with the added benefit of delivering coarse particles for the construction of tailings dam walls.
Selectively Capture Targeted Minerals
P29 can be applied to all sulphide minerals and is versatile in its ability to selectively capture its targeted minerals. It is a natural complement to an existing mine site.
Sustainability
Copper is a critical component of decarbonization. Electric vehicles, batteries, energy storage, high voltage wiring, wind turbines and photovoltaics all use copper as a fundamental enabler.
CiDRA’s P29 systems makes it possible to produce copper in a more sustainable manner by using less electricity, and water per ton of ore produced.
P29 Mineral Separation systems generate a coarse particle based waste stream. This is ideal for the construction of a new generation of more stable, safer tailings dam walls.
SONARtrac Flow Solutions
CiDRA’s line of SONARtrac flow meters is a breakthrough in flow measurement technology. Our passive sonar flow meters provide accurate and reliable flow measurements for a wide range of applications and industries. Over the years, our family of SONARtrac systems has evolved to include a variety of flow meters designed to measure single and multiphase flows from water to highly aggressive slurries. Due to their non-contact design, our sonar flow meters do not have any moving parts or process wetted parts that are subject to wear, or inherent drift mechanisms. Instead, they install easily on the outside of any type of pipe and provide years of service with no maintenance required.
