Complete your mine site with a proven FLS Merrill Crowe precious metal recovery system. Available in flowrates of 100m3/h to 2000m3/h, our plants reliably recover silver and gold and minimize excess zinc consumption. Experienced FLS application engineers are available to assist you with your needs.
Our Merrill Crowe systems include all necessary functions for effective precious metals recovery. From clarification, deaeration, zinc addition and precipitation through to refining, with all support utilities, our equipment is expertly selected and sized to meet your specific plant needs.
Designed and delivered to reduce onsite installation costs and complications, our Merrill Crowe systems are skid mounted, where possible. Process piping is pre-spooled with critical joints left loose for final welding onsite, while control panels are prewired, and connections matchmarked. Large equipment is disassembled and also matchmarked, as is structural steel.
Accessibility and maintainability are essential factors in the design of our Merrill Crowe systems. Equipment is laid out to optimise operations and maintenance access throughout the plant. The plant footprint has been minimised and piping systems are centrally located to allow forklift access. There is also forklift access between filters and to load the drying oven or retort pans. Most components are built from carbon steel with stainless steel available as an option – but it usually not necessary. Pipe flow velocities are kept reasonable to reduce maintenance and extend equipment life.
Our Merrill Crowe systems are usually supplied with FLSmidth-selected and customer-purchased initial plant startup and first- and second-year operation plant spares. We have dedicated plant startup and operator training engineers, and we offer future planning and troubleshooting services should your system contain copper or other deleterious species.
