Projects / Achievements: 1. October 2018 – Present: PAX Dosage Reduction Plant Trial. Preliminary data shows that operating the flotation circuit at lower PAX dosage and higher frother dosage is feasible without compromising recovery. Economical benefits is cost saving on PAX at AU$0.5 – 1M per annum. 2. 15th – 21st July 2018: Conducted Acacia Reactor Rinse Efficiency Testwork. This work illustrated that rinse efficiencies of >95% was possible from <90% as per the past plant set-up by increasing the super-pregnant solution drain time and adding additional rinse cycle which ultimately lead to extra recovered gold ounces of 415 Oz per day or 151,475 Oz annually equating to US$181.8M which is usually recycled back to the leaching circuit in the past where gold in solution losses was possible. Changes have been implemented on the Acacia drain and rinse sequence. 3. 1st – 6th July 2018: Commissioned a newly installed Mini Scales Crusher within the Regrind circuit to effectively crush >120mm sized scales worth of US$1.5M down to suitable size required to feed the regrind mills and improve the cyclone operating time to 100% because in the past, the scales usually ended up in the cyclone UF blocking the cyclone spigot and ultimately impact on cyclone availability to <90% availability. 4. March 2018 to Present: Pyrite Concentrate Export Plant Feed Upgrade Testwork which illustrated that extra 254 Oz of gold per day or 92,710 Oz annually equating to US$111.3M extra revenue generation was feasible. This work involves operating the flotation circuit at well-defined conditions and re-cleaning the scavenger concentrates to upgrade the gold grade at a gold upgrade ratio of 2.4. This work is currently under-going review for plant application. 5. 27th February 2018 to May 2018: When magnitude 7.5 Earthquake hit PNG, the power station at Porgera Gold Mine was damaged. With limited power supply onsite, we were faced with the challenge to generate revenue for the company to offset the operating cost and sustain the workforce. To produce gold ounces at a reduced rate, I was involved in designing Flotation and Leach Testwork programs with the implementation of recommended process flowsheet modifications from these testworks which ultimately lead to;
• Commissioning of Leach-CIP circuit with fresh pyrite concentrate (Autoclaves bypassed) attaining 60 – 70% recovery rate producing 400 – 600Oz of gold per day.
• Flotation of 50% GRG material at >85% flotation gold recovery rate.
• Operating the SAGMills and Ballmills at reduced power supply whilst maintaining the target P80 of 106µm in the final product. 1. January 2018 to February 2018: Was involved in high leach feed density trial at the Leach-CIP circuit. This work involved operating the Leach-CIP circuit at elevated density of 38% solids against the nominal operating density range of 28 - 30% solids which was focused at improving the residence time which was a success with Leach-CIP recovery improving to 95% or more from the nominal plant recovery of 93% or less as observed in the past equating to extra 10,950 Oz of gold production annually translating to US$13.14M extra revenue generation. 2. October 2017 to December 2017: Coordination of Ore Characterization Flotation Testwork. The recommendations from this testwork are currently being used to optimize daily flotation performance and maintain the target flotation recovery of 93% or more. 3. February 2017 to June 2017: Worked on the Metallurgical Accounting System Upgrade Project which involved setting up PI data links and complex spreadsheets. 4. October 2016 to February 2017: Conducted a Pilot Plant trial using Flotation Column with Cavitation Tube Sparge Technology on flotation tailings stream. Additional flotation gold recovery improvement of 0.3% translating to 1,867 Oz of gold annually was feasible equating to extra revenue of US$2.2M. This proposal is on hold to try larger means of fine gold recovery in the tailings. 5. January 2016 to June 2016: Automation of Cyanide addition via an in stream Free Cyanide Analyser at the Leach-CIP circuit. This work was focused on developing the control philosophy, SOP, training manuals, etc. and have this instrument online in an attempt to reduce cyanide consumption and improve recovery. Additional work is currently under-way to validate the reliability of this instrument before using it to dose cyanide. 6. July 2016 to October 2016: Commissioned the online Clarometer for the CCD circuit which was focused at reducing flocculant usage and improve thickener performance by online monitoring. Further upgrading of this instrument is currently in progress to ensure it is reliable for use. 7. August 2016 to December 2016: Installation and commissioning of the Cyanide Destruction Circuit in stream Cynoprobe analyser and Lab Cycnoprobe analysers. This work was focused at improving WAD Cyanide control / monitoring to maintain safe WAD Cyanide concentrations prior to discharging to the final tailings stream. 8. December 2015 to February 2016: Commissioning of Flotation Expert System which illustrated overall flotation recovery improvement to 93% or more from 91% as per the past plant set-up. My current role involves communicating with supplier of the expert system offsite and process control and maintenance teams onsite for fine tuning of the expert system and maintain 100% expert system utilization beefing up the flotation recovery to >93%. 9. April 2015: Was involved in substitution of incumbent frother with a new frother product which was a success with reduced frother consumption translating to a cost savings of USD$200,325 annually. Flotation gold recovery improvement by 0.6% was also feasible. This frother product is currently in use. 10. July 2017: Assisted the Senior Project Metallurgist in trialling out an alternative flocculant product (Rheomax 1050) which illustrated 40% reduction in flocculant consumption translating to AU$265,000 cost saving annually. 11. In January 2015, assisted the Senior Project Metallurgists to conduct plant survey and provide survey data to determine the possibility of adopting a Concentrate Desliming Circuit which was a success and Porgera is currently exporting fresh pyrite concentrate to offshore markets generating additional US$70-100M annually. 12. February 2014 to August 2014: Decommissioning of magnetic separator within the gravity circuit which ultimately lead to achieving more than 97% recovery rates via the Acacia Reactor as result of improved fine free gold recovery and achieving 100% Knelson Concentrator Utilization maximizing gravity gold recovery and improved flotation recoveries. 13. August 2013 to December 2013: Commissioned CIP Pond Reclamation Project (reclaiming concentrates stored in a pond for almost 10 - 15years equating to US$10M). This work included commissioning of the circuit, evaluating and establishing optimum operating parameters for the reclamation thickener, pump specifications, flocculent dosing rate determinations, developing of SOP and training Operators involved in operating this circuit. 14. March 2011 – July 2011: Was involved in Spent Fine Carbon Project. This work involved spent fine carbon from the Leach-CIP circuit collected for some time was valued up to US$1 - 2M and exported to overseas buyers. Based on this work, it is standard practice now at Porgera Gold Mine where the mine exports spent carbon valuing at US$1 – 2M after every 2 years generating additional revenue for the company. 15. 22nd – 24th July, 2014: Awarded Certificate in Crushing Operations and Maintenance Seminar which was completed in Perth, WA. 16. February 2016 to Present: Cyanide Code Representative for Porgera Joint Venture.
