Silver Bear Resources has ordered long lead process equipment items for its wholly owned Mangazeisky silver project in Yakutia, Russia, to boost silver recovery and cut operations costs.
The order was placed for electrowinning cell processing equipment, high-performance filters and a mill, with delivery expected to take place in 2016.
Using the electrowinning processing equipment ordered from Electrometals Group, the company said it will be able to produce solid silver powder directly from the leach solution.
According to Silver Bear, the technology offers increased production capacity, on a reduced footprint and better recoveries from lower concentrations.
For the project, Italian engineering and services group Bilfinger will supply two high-performance filters, which have built in cake-washing capability and constitute the essential final stage in the separation of silver bearing solution from the barren solids.
Separately, the company will purchase a mill from Metso for regrinding the gravity concentrate.
The gravity concentration and intensive leaching is expected to cut cyanide consumption and improve silver recovery.
Silver Bear also awarded a procurement services contract to Russian company PT Mining for the ongoing Mangazeisky project.
Under the contract, PT Mining will compile packages of equipment and materials to supply complete process plant sections in partnership with Silver Bear’s own procurement specialists and Tetra Tech.
Silver Bear Resources CEO Graham Hill said: "Over the 2015 field season, the company has embarked on an aggressive project implementation programme and the ordering of key long-lead items such as the ball mill and the electrowinning equipment, and the award of the procurement services contract are all significant milestones in the project’s development.
"At this time, the accelerated construction and mine plan for the Vertikalny deposit is progressing well and we are confident that the company is in the position to meet its target of commissioning silver production by the second half of 2016."
In October 2004, the company acquired a 100% interest in the Mangazeisky project located 400km north of the capital city of Yakutsk.
