Unit of Competency MSL975041 - Perform fire assay techniques
Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the skills and knowledge to safely extract a range of precious metals from their host matrices in readiness for analysis. The unit also covers the ability to select and/or modify laboratory methods to suit particular ores and to ensure total recovery.This unit applies to laboratory personnel working in the mineral assay industry sector.No licensing or certification requirements exist at the time of publication. However, regulations and/or external accreditation requirements for laboratory operations exist, so local requirements should be checked. Relevant legislation, industry standards and codes of practice within Australia must also be applied.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Elements of Competency Performance Criteria              
Element: Classify ore samples and select fluxing method
  • Review client request to identify sample/analysis requirements, preparation methods and equipment involved
       
Element: Inspect samples, compare with specifications, record and report any discrepancies
       
Element: Conduct visual and simple chemical tests to identify the type of sample and sulphide concentrations
       
Element: Review client sample/analysis history and identify possible chemical interferences
       
Element: Decide whether non-standard fluxing is required
       
Element: Select sample weight and flux to optimise precious metal recovery and purity
       
Element: Prepare for precious metal recovery
  • Identify hazards and workplace safety procedures associated with the sample, preparation methods, reagents and equipment
       
Element: Examine the recommended preparation method to identify the critical steps that will affect the quality of analytical results
       
Element: Plan parallel work sequences to optimise the throughput of multiple sets of samples
       
Element: Assemble all required equipment, materials, reagents and check they are fit for purpose
       
Element: Recover precious metals from ore sample
  • Weigh required amounts of sample and flux components to achieve an acceptable button and fluid slag
       
Element: Select the type and size of pot to suit sample method and client requirements
       
Element: Mix charge to ensure homogeneity and optimal collection of precious metal
       
Element: Set and monitor furnace temperature/time to ensure complete fusion
       
Element: Separate slag and button with minimal loss of lead collector
       
Element: Maintain sequencing in order to track samples, buttons and prills throughout the recovery process
       
Element: Separate lead collector from the required precious metal and check for contamination, losses and evidence of other precious metals
       
Element: Minimise personal exposure to hazards and the release of collectors to the work environment
       
Element: Collate laboratory documentation and the prepared sample and present for analysis
       
Element: Troubleshoot and correct failed recovery
  • Monitor all stages of recovery for indicators of potential loss
       
Element: Recognise undesirable recovery conditions and decide whether the process requires correction
       
Element: Choose an appropriate corrective action and re-start the process
       
Element: Document any adjustments made to standard methods and re-sequencing of samples
       
Element: Seek advice when problems are beyond scope of responsibility or knowledge
       
Element: Perform daily maintenance of assay equipment
  • Segregate and dispose of waste in accordance with workplace requirements
       
Element: Grade and inspect pots using established criteria prior to storage for re-use
       
Element: Inspect furnaces for cracks, unserviceable components and remove slag
       
Element: Inspect and clean extractive systems
       
Element: Report defective equipment and consumable requirements to appropriate personnel

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
