Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:
locates and applies relevant documentation, policies and procedures
implements the requirements, procedures and techniques for the safe, effective and efficient completion of thickening and clarifying processes including:
conducting start up, shut down and/or isolation of equipment in sequence
operating and monitoring equipment
carrying out minor maintenance
conducting housekeeping activities
diagnosing faults, reporting defects and identifying repair requirements
applying lifting techniques (manual, automated)
works effectively with others to undertake and complete the thickening and clarifying processes in a way that meets all of the required outcomes including:
using a range of communications techniques and equipment to convey information to others
maintaining written and verbal reporting requirements and procedures
organising work activities to meet all task requirements
communicating clearly and concisely with others to receive and clarify work instructions
demonstrates completion of thickening and clarifying processes that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:
identifyingand interpreting data from equipment indicators to determine torque, bed characteristics, flow characteristics and reagent dosage
continuously inspect plant
controlling discharge of underflow/overflow agents to agreed operating parameters
directing underflow/overflow to alternate location according to work specifications
monitoring performance of thickener to meet agreed operating parameters
The candidate must demonstrate knowledge of conduct thickening and clarifying process through:
accessing, interpreting and applying organisation and site requirements and procedures for:
WHS, site safety and emergency requirements
environmental principles/procedures
equipment safety requirements

identifying reagent types
identifying types of ores
An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
this unit must be assessed in the context of this sector’s work environment; and,
this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:
Industry sector | AQF** Level | Required assessor or Industry subject matter expert experience |
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction | 1 | 1 Year |
2 | 2 Years |
Drilling, Coal Mining and Extractive (Quarrying) | 3-6 | 3 Years |
Metalliferous Mining and Civil Construction | 3-6 | 5 Years |
Other sectors | Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation. |
*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.
**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
