272 XXXI International Mineral Processing Congress 2024 Proceedings/Washington, DC/Sep 29–Oct 3
As part of this initiative, a project is underway to
drive the development of JKMRC’s continuous HVP elec-
trode-grizzly system towards commercialization, targeting
a Technology Readiness Level TRL of 6–7 (technology
demonstrated at scale). This project encompasses several
key objectives aimed at overcoming barriers to the success-
ful and widespread adoption of High Voltage Pulse HVP
technology in the minerals industry, including scalability,
implementation, reliability, and cost-effectiveness. The
main aims of the project include:
1. Extensive Assessment: The project includes a
comprehensive assessment of the HVP-treated
products, focusing on pre-weakening, pre-concen-
tration, and mineral recovery through both con-
ventional and novel processes such as HydroFloat
technology.
2. Business Case Development: A thorough busi-
ness case will be developed to justify the use of
HVP technology, including a techno-economic
analysis of different circuit options integrating the
technology.
3. Pilot-Plant Design: Detailed design and fabrica-
tion of a pilot-plant unit will be undertaken to
test, optimize, and demonstrate the HVP Grizzly
system in real-world conditions.
4. Commercialization Pathway: The project will out-
line a clear commercialization pathway for the
HVP Grizzly system, addressing factors such as
scalability, implementation costs, reliability, and
market demand.
By addressing these key objectives, the project aims to pave
the way for the successful adoption of HVP technology in
the minerals industry, ultimately enhancing productivity,
efficiency, and sustainability in mining operations.
CONCLUSIONS
High Voltage Pulse (HVP) Technology presents a promising
opportunity for the mining industry, offering multiple ben-
efits and addressing various challenges it is currently facing.
The advent of the electrode-grizzly system has showcased
the technology’s scalability to meet the throughputs neces-
sary for mining operations. It is an innovation that repre-
sents a pathway for integrating HVP technology into the
mining industry. This concept was specifically designed to
process significant tonnage rates while minimizing the pro-
cess footprint, making it a promising solution for enhanc-
ing efficiency and sustainability in mining operations.
Technological progress has the potential to revolution-
ize the mining sector and assist in overcoming the challenges
it is currently facing. However, transitioning a technol-
ogy from conceptualization to market readiness demands
substantial investments in time, resources, and specialized
knowledge. Effective collaboration among governmental
bodies, research entities, industry players, and other stake-
holders is imperative to navigate the intricate stages of tech-
nology evolution and realize successful implementation.
