Full process flowsheet for a Hindustan Zinc concentrator plant 

F‌LSmidth has received an order from Hindustan Zinc Limited (HZL) to design and supply the main process equipment across the flowsheet for a lead-zinc concentrator plant. FLSmidth will deliver all the key process equipment for a newly modernised beneficiation plant that will replace the previous facility. The equipment includes rod-ball mills, flotation cells, thickeners, hydro cyclones, pumps, Pneumapress filters, slurry samplers, process control valves/instruments and tagged electricals.


Digital and automation solutions such as an online slurry analyser, advanced process control and automation, as well as the PlantVision™ tool will be provided as part of the package. PlantVision is a real-time image analysis solution that provides critical measurements for ore on conveyor belts or froth properties in flotation cells. The plant performance is backed by a bench scale test conducted at the FLSmidth Minerals Testing & Research Center, Salt Lake City. FLSmidth will complete the delivery of the equipment and plant commissioning before the end of 2022, when the plant will be ready to process the first feed.
