The plant also has latent capacity to process up to 1Mtpa of hard rock ore concurrently with tailings. Key equipment includes: Primary crushing facilities, grinding facilities consisting of one SAG mill and two balls mills; fifteen ultrafine sand mills; a conventional froth flotation circuit, Full site laboratory capable of handling all exploration and plant samples; and Equipment workshops and stores for all mobile and fixed plant maintenance.
The km buried slurry pipeline is a unique and leading-edge design for a pipeline in Australia. Providing unmatched access to the coast for the region, the pipeline is buried over most of its length to a depth of approximately 1m. Zinc concentrate has been pumped from concentrate storage tanks at the Lawn Hill site to the Karumba Port Facility. More on:. Top Stories Queen sprains back, won't attend Remembrance Sunday event.

The main production phase will mine the Deposit leaving a mm loss on the floor of the deposit while taking mm of dilution in the main production pass. A separate clean-up crew will follow the production crew after a period of time, in order to remove the remaining contaminated material and an additional mm of dilution.
This material will be mostly bypassed to the open pit void as waste. This clean up forms part of the final rehabilitation process for the TSF area.
The mine design has two sumps, which provides greater flexibility in the mine plan, and reduces the risk of significant downtime during heavy rain events.
Tailings slurry from hydraulic mining will be passed over a trash screens before being sent to a feed thickener. The purpose of the feed thickener is to ensure consistent density and flow rate into the Century Processing Plant. The Plant will have sufficient surge capacity for 2 hours of production to further assist in smoothing production. Milled material will be combined with cyclone overflow and sent to one of two parallel flotation circuits. The flotation circuit consists of rougher, scavenger and cleaner circuits in each train.
Regrind mills are used on cleaner 1 concentrates to improve recovery of zinc. The final zinc concentrate is thickened and pumped to concentrate storage tanks prior to being pumped to the Karumba Port facility via the underground slurry pipeline. Production :.
