Run and Control the Operations of Processing Plant
This element focuses on the practical skills and underpinning knowledge required to safely and efficiently operate and control mineral processing plant, such as crushers, screens, conveyors, and mixers, ensuring product quality meets specifications while maintaining equipment and minimising downtime. Learners must demonstrate competence in start-up, shutdown, and monitoring procedures, adjusting plant settings in response to process conditions, and adhering to health, safety, and environmental regulations.
Assessment criteria
Topic Overview
The MPQC Level 2 Diploma in Mineral Products Processing Operations is a vocational qualification designed for individuals working in the extractive and mineral processing industries. It covers the fundamental skills and knowledge required to operate processing plant equipment safely and efficiently, including crushing, screening, washing, and conveying systems. This diploma is essential for those pursuing a career in quarrying, mining, or construction materials production, as it ensures compliance with health and safety regulations and industry best practices.
The qualification is structured around mandatory units that address core competencies such as health and safety, environmental awareness, and operational procedures. Learners develop practical skills in monitoring plant performance, conducting routine maintenance, and responding to process variations. By completing this diploma, students demonstrate their ability to contribute to a productive and safe working environment, which is highly valued by employers in the mineral products sector.
This topic fits into the wider Manufacturing & Engineering framework by providing a specialised pathway for those in heavy industry. It builds on basic engineering principles and applies them to real-world processing operations. Understanding this qualification helps students appreciate the importance of quality control, resource efficiency, and sustainable practices in mineral extraction and processing.
Key Concepts
Core ideas you must understand for this topic
- →Health and Safety Regulations: Understanding the Health and Safety at Work Act 1974, COSHH, and PPE requirements specific to mineral processing sites.
- →Processing Operations: Knowledge of crushing, screening, and washing processes, including equipment like jaw crushers, cone crushers, and vibrating screens.
- →Quality Control: Monitoring product specifications such as particle size distribution and moisture content to meet industry standards.
- →Environmental Management: Implementing dust suppression, noise control, and water management to minimise environmental impact.
- →Maintenance Procedures: Performing pre-start checks, lubrication, and basic fault-finding to ensure equipment reliability.
Learning Objectives
What you need to know and understand
- 1. Be able to run and control the operation of processing plant.2. Understand how to run and control the operation of processing plant.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic start-up sequence, including all pre-start checks (guarding, lubrication, isolation) and verification of correct sequencing as per standard operating procedures.
- Evidence must show continuous monitoring of key process parameters (e.g., feed rate, screen deck angles, crusher gap settings) and prompt adjustments to maintain product size, shape, and throughput within tolerance.
- Assessors should observe and record the candidate's response to simulated or real plant alarms or deviations, such as blockages, sensor faults, or emergency stops, following correct fault-finding and reporting protocols.
- Candidates must display competent use of control room interfaces (where applicable) and manual overrides, demonstrating understanding of interlock systems and safe isolation before any intervention.
Assessment Guidance
Guidance for achieving higher grades
- 💡In observation-based assessments, narrate your actions clearly, explaining why you are performing each check or adjustment—this demonstrates underpinning knowledge to the assessor.
- 💡When providing portfolio evidence, include annotated photographs, signed check sheets, and witness testimonies that explicitly reference the relevant learning outcomes and performance criteria.
- 💡For written or oral questioning, use industry-standard terminology (e.g., ‘closed side setting’, ‘throw’, ‘stroke’) and link your answers to real workplace scenarios to show application of theory.
- 💡Tip 1: Use specific examples from your workplace when answering questions about procedures. This shows practical understanding and can earn higher marks.
- 💡Tip 2: Memorise key safety acronyms like COSHH, RIDDOR, and PUWER. Examiners look for correct terminology in written answers.
- 💡Tip 3: When describing a process, include the purpose of each step. For example, explain why screening separates materials by size and how it affects downstream operations.
Common Mistakes
Common errors to avoid in your coursework
- Omitting or rushing pre-start checks, particularly those for isolation or guarding, assuming the plant is ready because it was functioning in the previous shift.
- Failure to sample and test product at required intervals, leading to off-spec material being produced and not identified until a larger batch is contaminated.
- Adjusting only one processing variable (e.g., crusher setting) without considering the impact on downstream equipment or overall plant balance, causing bottlenecks or overloads.
- Ignoring warning signs of equipment distress (unusual noises, vibrations, temperature rises) and continuing operation, leading to premature wear or catastrophic failure.
- Misconception: 'Safety procedures are optional if I'm experienced.' Correction: Safety is mandatory regardless of experience; complacency is a leading cause of accidents in mineral processing.
- Misconception: 'All crushers work the same way.' Correction: Different crushers (jaw, cone, impact) have distinct operating principles and are suited to different materials and stages of processing.
- Misconception: 'Quality control is only the lab's responsibility.' Correction: Operators must continuously monitor product quality and adjust settings to maintain specifications.
