256626 | Flux samples in preparation for the fire assay fusion | Level 2 | NQF Level 02 | 6 |
PURPOSE OF THE UNIT STANDARD |
This unit standard is for persons required to prepare flux and for fluxing samples in preparation for fusion. It will apply to laboratory personnel on a precious metal mine. A person credited with this unit standard will be able to:
|
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |
The credit calculation is based on the assumption that learners are already competent in terms of the following outcomes or areas of learning when starting to learn towards this unit standard:
Proficiency in the use of lifting equipment. |
UNIT STANDARD RANGE |
Specific range statements are provided in the body of the unit standard where they apply to particular specific outcomes or assessment criteria.
Applicable to the fluxing of material containing any of the precious metals. |
Specific Outcomes and Assessment Criteria: |
SPECIFIC OUTCOME 1 |
Flux samples in preparation for the fire assay fusion. |
ASSESSMENT CRITERIA |
ASSESSMENT CRITERION 1 |

2. Flux samples in preparation for fusion. |
SPECIFIC OUTCOME 2 |
Prepare for fluxing. |
ASSESSMENT CRITERIA |
ASSESSMENT CRITERION 1 |
1. Hazards and risks pertaining to the fluxing process are identified and explained with reference to team health and safety and environmental impact. The appropriate preventive measures are listed and applied in accordance with specified requirements. |
ASSESSMENT CRITERION 2 |
2. The required personal protective equipment is available, operational, fit for purpose and used in accordance with specified requirements. |
ASSESSMENT CRITERION 3 |
3. Work is conducted to meet health, safety and environmental standards and specified requirements. |
ASSESSMENT CRITERION RANGE |
Health, safety and environmental issues must include:
|
ASSESSMENT CRITERION 4 |
4. Equipment needed for the process is identified, and is in good working order according to specified requirements. |
ASSESSMENT CRITERION RANGE |
Equipment must include:
|
ASSESSMENT CRITERION 5 |
5. The sample is visually inspected and verified prior to fluxing in accordance with specified requirements. |
ASSESSMENT CRITERION 6 |
6. The flux reagents are correctly identified, verified and selected in accordance with the specified formula requirements. The use of each flux reagent is explained with reference to its primary purpose during the fusion process. The need for different flux formulae is explained in terms of sample composition. |
ASSESSMENT CRITERION 7 |
7. The prepared flux meets the formula requirements for the specified process. It is homogenous and a flux test shows that t is free of contaminants and that the button weights are in the specified range. The reasons for checking the prepared flux and performing blank determinations are explained in accordance with specified requirements. |
ASSESSMENT CRITERION 8 |
8. The consequences of incorrect measurements and ineffective mixing are explained in terms of the effect on the assay process. |
SPECIFIC OUTCOME 3 |
Flux samples in preparation for fusion. |
ASSESSMENT CRITERIA |
ASSESSMENT CRITERION 1 |
1. Equipment is used in accordance with specified requirements. The importance of cleanliness is explained with reference to the risk of contamination. |
ASSESSMENT CRITERION RANGE |
Equipment must include:
|
ASSESSMENT CRITERION 2 |
2. The required personal protective equipment is used in accordance specified requirements. |
ASSESSMENT CRITERION 3 |
3. The quantity and type of flux used is appropriate for the particular sample type and mass. The mixture of sample and flux is homogenous in appearance. |
ASSESSMENT CRITERION 4 |
4. Fluxed samples and controls are sequenced, coded and recorded according to specified requirements. The importance of sequencing in the fluxing process and the use of an identification pattern is explained with reference to maintaining unique sample identification. |
ASSESSMENT CRITERION 5 |
5. The purpose of including control samples and replicates is explained in terms of maintaining process and quality control. |
ASSESSMENT CRITERION 6 |
6. The work is conducted to meet health, safety, environmental standards and specified requirements. |
ASSESSMENT CRITERION RANGE |
Health, safety and environmental issues must include:
|
ASSESSMENT CRITERION 7 |
7. The consequences of non-compliance with specified requirements are explained with respect to personal and team health and safety, impact on the environment, production, quality, costs and lost time. |
ASSESSMENT CRITERION 8 |
8. The work is conducted in a manner that ensures continuity throughout the process. |
UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS |
1. Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
2. Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA by SAQA. 3. Moderation of assessment will be overseen by the relevant ETQA according the moderation guidelines in the relevant qualification and the agreed ETQA procedures. |
UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE |
Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Candidates are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the candidate`s performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the unit standard. The following embedded knowledge is addressed in an integrated way in the unit standard: |

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: |
This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here. |
