Chita — Nornickel has commenced pre-commissioning of the second line of the concentrator at Bystrinsky GOK. The first pilot commercial production of gravity gold concentrate is expected by the end of 2017.
Pre-commissioning of the grinding shop’s second line started on 16 November and is scheduled for completion by 10 December 2017 at the latest. Works on the second line’s conveyor belt and equipment — the main system used to feed crushed ore stored in a stockpile to the grinding shop — commenced on December 1, as planned.
“The Bystrinsky Concentrator construction was completed in record-breaking time. Now we are progressing with pre-commissioning and are fully on track. The pilot commercial product output is expected by the year-end,” Sergey Dyachenko, First Vice President and Chief Operating Officer of Nornickel, said.
The Company commenced pre-commissioning of the first processing line of Bystrinsky GOK on 31 October. By now, it has completed no-load pre-commissioning of the first line’s ore feeding system, grinding shop, gravity gold recovery section, tank pumps for discharging flotation tailings to the tailing dump, pump station of the water recycling system and slurry pumps. Works on the tailing dump’s pump station and service water pump stations that supply water from the water reservoir to the concentrator have also been completed. Today, the operating water circuit covers the water reservoir, the concentrator and the tailing dump.
Pre-commissioning of the first line’s flotation and filtering equipment as well as copper concentrate thickeners is underway.
Each line has the ore processing capacity of 5 mtpa. The concentrator is expected to run in the pre-commissioning mode for a few months, switching to normal operation by mid-2018 and reaching design capacity in late 2019.
