Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Sources of information may include:
reference texts,
manufacturer's catalogues
industrial and professional magazines and journals,
colleagues
websites,
phone, email and fax information gathering

Equipment in mineral and chemical processing plants can include equipment for:
Transport and storage of materials
Heat transfer
Solids drying
Phase dispersion and separation
Gas solid operations
Liquid liquid operations
Liquid solid operations
Solid solid operations
Size reduction and size enlargement
Bulk solid handling
Packaging of solids and liquids
Chemical reactors
Waste management
Process safety
Energy generation and utilisation

Scientific techniques and principles include:
Principles of mineral processing
Principles of chemical processing
Function of each type of equipment
Flow diagrams
Processes for particle size change
Processes for separation of materials

EVIDENCE GUIDE
The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment
A person who demonstrates competency in this unit must be able to apply basic scientific principles and techniques in describing equipment for mineral and chemical processing.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the ability to:
identify appropriate techniques and equipment used for mineral and chemical processing
function of each type of equipment
steps in the processing of particular minerals and chemicals including flow diagrams
identify relationship of the processing of particular minerals and chemicals to metals production
Relationship to other units
This unit may be assessed concurrently with MCMPM518A Specify basic metal extraction processes from minerals
Assessment method and context
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the elements, performance criteria, skills and knowledge. A holistic approach should be taken to the assessment.
Assessors should gather sufficient, fair, valid, reliable, authentic and current evidence from a range of sources. Sources of evidence may include direct observation, reports from supervisors, peers and colleagues, project work, samples, organisation records and questioning. Assessment should not require language, literacy or numeracy skills beyond those required for the unit.
The assessee will have access to all techniques, procedures, information, resources and aids which would normally be available in the workplace.
The method of assessment should be discussed and agreed with the assessee prior to the commencement of assessment. Assessment will need to occur in a situation where mechanical testing is undertaken.
Resource implications
This section should be read in conjunction with the range of variables for this unit of competency. Resources required may include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
