Noticeable contributions:- Transformed a team of green flotation operators into fully competent and skilled operators - Improved operational consistency across all crews through introduction of revamped shift instructions, operational TARPS and area guides.- Implemented an empowerment tool/project which developed a team of highly trained operators to build a positive and safe working environment and delivered uplift in metal production. (Upskill Program)- Debottlenecking of process plant through operational audits, identified major constraints and risks. This allowed the correct focus on key areas leading to achievement of higher plant throughput and availability. - Improved safety attitude and culture amongst the team through leading by example and safety representative. (Reshaped safety culture and eliminating complacency)- Improved day to day plant performance through establishing routine diagnostic test regime and trained graduate metallurgist and metallurgy technicians. (Hotfloats, size x size and refloats)- De-bottlenecked Tailings Thickener by establishing a system to measure and track process water quality and design modifications. Show less
