Utilization of lead-zinc tailings

Tailings are traditionally named according to their sources, the ore body, for example iron ore tailings, lead-zinc tailings, copper tailings, gold tailings, oil sands tailings, and so on. Researchers making materials often use this classification method, but it does have some limitations, for it cannot reflect the nature of the tailings and

Mount Polley mine

Mining Operations When operating, the Mount Polley mine moves 80,000-90,000 tonnes of material per day from the mine. This consists of 20,000 tonnes of ore. Mount Polley does not require high-skilled labour for operations and hires and trains from the local communities of Big Lake, Horsefly and as far away as Quesnel and Williams Lake.

Study on the Strength Development of Cemented Backfill …

As can be seen from Figure 3, for the tailings in sulfur compound lead-zinc ore, no matter it is coarse fillings or fine fillings, only by being mixed with OPC as the binder and curing the cemented backfill body for 360 d, there will be visible cracks on all cemented backfill bodies, and the cracking of the fine tailings test samples is the most serious; in the coarse tailings, in addition to ...
