O&M services, supported by KPIs
Outotec’s O&M services agreement includes the disciplines of operation and maintenance, management and leadership, reliability, planning and scheduling, continuous improvement and health and safety. Central to this O&M agreement are Key Performance Indicators (KPIs).
At the core of Outotec’s O&M Services is the concept of “shared risk”, measured by KPIs. An agreement in pricing structure between Outotec and Capricorn Copper is based around key KPIs such as safety, availability and paste quality. Coupled with a fixed monthly fee, this approach ensured that there is vested interest from both parties for a successful paste operation.
Additionally, having one partner from concept to operations ensures the operational profitability is directly related to reliability of all plant assets, systems and underground fill system components. Additionally any warranty, system failures and related issues are quickly analysed, rectified and improvements sought.
MPB 80 = accelerated and smooth commissioning
Due to the MPB 80 modular design, the Capricorn Copper plant was installed and commissioned in an accelerated start-up phase. Furthermore, as the plant was fully integrated with the upstream process plant as well as the downstream underground reticulation and management systems, the entire operation worked seamlessly. The plant began operating immediately at design fill rates.
Expertise in underground operations
Outotec’s vast experience in mining backfill promotes an efficient and effective implementation of an operate and maintain contract. Experienced plant trainers deliver fasttracked training to minimise downtime in the ramp-up period. Supervisors and engineers on site offer guidance in paste fill implementation in underground operations, as well as technical support to the client on all matters relating to the mine backfill process.
MPB 80, plus O&M services = optimised maintenance
One of the features of the MPB 80 design is its low maintenance. Due to its compact and innovative design, minimal process material build-up and spillage is generated during operation. The MPB 80 can therefore operate for multiple shifts without shutting down for cleaning. This represents a major improvement over previous plant designs which are normally shut down at the end of each shift, at least, to clean away build-up of paste in the plant’s paste hopper. The vortex mixer also provides significant design improvement by way of pre-dissolving the binder with slurry before it enters the paste mixer, thereby also delivering a lower maintenance plant.
As part of Outotec’s O&M services, the plant-specific Computerised Maintenance Management System (CMMS) ensures that all preventative and unscheduled maintenance is tracked and monitored closely to ensure plant reliability remains optimal. Through regular weekly meetings with an Outotec maintenance specialist, routine and non-routine tasks are discussed to ensure that all maintenance is undertaken in a timely and safe manner.
Enhanced design leading to enhanced quality
At the core of the Outotec MPB 80 design process is Outotec’s industry leading plant design and automation. Through nearly 20 years’ experience in the mine backfill industry, the MPB 80 plant represents a highly sophisticated plant with intricate control over all inputs into paste fill production. Coupled with a high degree of automation and human-machine interface control, the MPB 80 is an industry leading design. Intricate and precise control over the production process ensures high quality of the paste fill, drastically minimising the risk of paste-associated complications further in the mining sequence.
Flexible to varying feed conditions
Significant variations in the tailings characteristics required design modifications, new parts and changes in parts. This is being achieved through on-site Engineering and Operations personnel, backed by technical experts from various disciplines. One of the major benefits of a performance service partnership is “access to offsite technology expertise.”
Josh Moran, Underground Mining Manager at Capricorn Copper, explains that “the Outotec modular paste backfill plant was an ideal solution, with fast installation and immediate operation at design fill rates. The integral paste mixer and hopper also reduced our plant footprint.”
Mr Moran continues “Outotec’s ongoing operate and maintain of our paste backfill plant has also delivered value to Capricorn Copper”.
