Yukon Zinc has now advanced the Wolverine zinc-silver deposit to production, making it the first operating mine in the Finlayson District of the Yukon Territory. Wardrop Engineering awarded Team Mixing the engineering & supply contract for the cement slurry portion of the mines pastefill system.

The onboard PLC control system & touchscreen, which communicates with the main pastefill plant DCS system, features multiple recipe selection, alarming and data logging for each batch. The DCS controls cement slurry consumption in a continuous system. A VFD modulates the discharge rate of slurry from the progressive cavity pump to coincide with the dewatered tailings feed rate into the pastefill mixer. A Putzmeister piston pump transfers the pastefill to the underground workings.

The plant is skid mounted and fully prewired and plumbed for water and air. The plant features the new Mk IV mechanical seals on the colloidal mills which reduce maintenance and increase lifespan.

The motors are also direct coupled to the colloidal mills and use VFD’s to increase the motor speed to the required 2100 rpm operating requirement of the mills.
