Laurie Reemeyer, Principal Consultant, Resourceful Paths; Advocate and Technical Expert, CEEC International
Laurie is the Principal Consultant at Resourceful Paths, a sustainability and strategy consultancy he established in 2016. Resourceful Paths is focused on reducing energy and water use in mining, mitigating climate change and maximising resource recovery. Laurie is also a CEEC Advocate and helps lead the Global Water Initiative and the Global Tailings Initiative; two collaborative CEEC programs to improve the eco-efficiency of mineral resource development.
Laurie has 24 years’ base metals and gold mining operations and consulting experience. As Plant Metallurgist at Mount Isa Mines, he worked with a team of metallurgists to configure the AG/SAG/ball mill circuit to operate efficiently at a range of throughputs through optimising ball charges, cyclone configurations and operating parameters. At Elura and Century mines, he improved operation of fine stirred mill regrind circuits.
He led the Process Engineering team at Amec Foster Wheeler in Vancouver. The team provided design, due diligence and operational support services for crushing and grinding, flotation, dewatering, smelting, hydrometallurgy, paste backfill and water treatment in commodities including copper, gold, nickel, zinc and diamonds. He has also led several studies, including the Oyu Tolgoi feasibility study update and Blackwater PEA.
Laurie is committed to using mineralogy and laboratory ore characterisation data to determine optimal flotation feed and regrind sizes that balance concentrate grades and metal recoveries with energy and media costs. He also assesses opportunities for selective mining and pre-concentration to reduce energy currently expended on grinding uneconomic particles. He has a Bachelor of Engineering (Minerals Process) from University of Queensland and an MBA (Certificate in Business and Engineering Sustainability) from UC Berkeley.
