Employability Skills | |||
Learning Outcomes and Application | This unit of competency covers the ability to follow standard procedures for extracting precious metals from their host matrices in readiness for analysis. Fire pourers are expected to handle routine samples, recognise common sample preparation and cupellation problems and make standard adjustments to fluxes and firings. They are expected to seek advice from their supervisor when non-routine problems arise.This unit of competency is applicable to laboratory personnel working in the mineral assay industry sector.While no specific licensing or certification requirements apply to this unit at the time of publication, laboratory operations are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Judgement of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event. This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills. Foundation skills are integral to competent performance of the unit and should not be assessed separately. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case). This unit of competency may be assessed with: MSL953001 Receive and prepare samples for testing MSL943002 Participate in laboratory or field workplace safety Holistic assessment methods include: review of quality control performance and analytical results traceable to assay samples prepared by the candidate review of sample records prepared by the candidate feedback from supervisors, peers and/or clients about the candidate’s ability to provide acceptable buttons and prills and troubleshoot and correct common recovery failures written/oral questions about fire pouring techniques, typical recovery problems and corrective actions. Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to: a variety of precious metal ore samples and associated fire assay methods, fire assay materials and reagents client requests and documentation, such as client profile, sample identification, sample receipt, storage and analyses, required preparation method and service charges assay equipment, such as: mixing equipment and balances fusion and muffle furnaces and associated spares temperature sensors and hotplates compressed air service, extraction systems and fuel supply lines cupels, pouring equipment, pot loader, trolleys, moulds, tongs and hammers pots, including ceramic, acidic/basic, alumina, zirconia and graphite collectors, including litharge or lead (II) oxide (PbO) for pot fusion and silver (AGNO3) for the cupellation fluxes, including: bulk fluxes containing lead (II) oxide (PbO), borax, soda ash, silica, silver nitrate and flour non-standard flux additives, such as: flour (oxidising samples) potassium nitrate (reducing samples and sulphides) silica (basic ores) lead as PbO (siliceous ores) safety equipment and safe work procedures. Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator. The assessor must demonstrate both technical competence and currency. Technical competence can be demonstrated through: relevant VET or other qualification/Statement of Attainment AND/OR relevant workplace experience. Currency can be demonstrated through: performing the competency being assessed as part of current employment OR having consulted with a laboratory about performing the competency being assessed within the last twelve months. |
