Process technology group FLSmidth has been retained by Indian miner Hindustan Zinc for the design and supply of the main process equipment cross-flowsheet for its concentrator plant.

Under the outlines of the order, FLSmidth will deliver all key process equipment for a newly modernised beneficiation plant to replace its previous facility, including rod-ball mills, flotation cells, thickeners, hydro cyclones, pumps, Pneumapress filters, slurry samplers, process control valves/instruments and tagged electricals. 

The facility’s digital and automation solutions will include an online slurry analyser, advanced process control and automation, and the PlantVision real-time image analysis solution that can provide critical measurements for ore on conveyor belts or froth properties in flotation cells. 

Mikko Keto, president of mining at FLSmidth, confirmed the plant performance is backed by a bench scale test it conducted at the FLSmidth Minerals Testing and Research Center in Salt Lake City, Utah, USA. 

“We are also excited to supply the first flotation cells with nextSTEP rotor/stator in this region and to be providing digital and automation solutions, which include an advanced automation control for the lead-zinc concentrator,” he said. 

“Digital is a crucial tool for process optimisation as it allows for greater efficiency in resource use, better throughput and an improvement in sustainable productivity.”

Delivery of the equipment should be completed and the plant commissioned before the end of 2022, after which the plant will be ready for first feed.
