Optimizing the World's Hydromet Facilities
Our Mission
NOVA Hydromet is a joint venture focused on creating an efficient and sustainable global metal extraction industry. We provide science-based guidance and technology to optimize the world’s hydrometallurgical facilities.
A Holistic Approach to Autoclave Systems
Technical Consulting and Modelling
The severe service nature of hydrometallurgy process conditions and the high value of target metals creates a condition where failures are both common and costly.
NOVA’s approach is to help your team bridge scientific disciplines by utilizing mathematical modelling, controls programming, and trim sizing techniques to find lasting solutions to autoclave production problems.
Common problems NOVA’s technical staff can help resolve:
- broken valve trim
- erosion
- scale build-up
- low ore yield
- unexpected shut-downs
Core sciences include:
- control theory
- multi-phase fluid flow theory
- thermodynamics
Equipment Repair and Servicing
NOVA focuses on solving the root problem behind equipment failures, as well as providing superior equipment servicing and replacement parts.
While autoclave issues can manifest as costly broken equipment, greater losses often come from unscheduled shutdowns, below-nameplate throughput, or incomplete ore reaction. The causes of these issues are often complex, originating from multiple sources.
The disciplines we use to solve equipment problems include:
- ceramic fracture mechanics
- erosion testing
- data analytics
In partnership with your site, NOVA will analyze broken equipment and provide application-specific replacements, as well as gathering and analyzing operating data to determine what deeper problems may exist and how production can be increased.
Equipment Enhancement and Sales
NOVA’s technical consultants can help you determine which equipment best fits the needs of your site.
Specific to the autoclave mining industry, NOVA has developed its own forged-body Letdown and Vent Angle control valves which are custom-made for each application.
NOVA Hydromet supplies a range of top-of-the-line equipment, including:
- Letdown Control and Vent Angle Control Valves
- Metal Seated Ball Valves (MSBVs)
- Severe Service Knife Gate Valves (SSKGVs)
- Engineered Check Valves
- Fit-For-Purpose Control Valves
NOVA supplies an ecosystem of severe service equipment products to support autoclave operations.
