This Proterozoic host sequence is truncated up-plunge in then Northern Zone at the sub-horizontal unconformity with the younger Cretaceous sediments that are between 10 m and 60 m thick in the Cannington Operations area.
The Southern Zone has a strike length of m to m and extends to approximately m below surface. The metamorphosed sediment package has been folded into a synform structure and is displaced on a local scale by north northeast and northeast trending faults.
The northeast trending faults are interpreted as conjugate sets to the Trepell and Hamilton Faults as a result of sub- horizontal sinistral movement. The Northern Zone strike is approximately m and extends to around m below surface. It is less deformed than the Southern Zone and typically dips east, interpreted as being the eastern limb of an antiform. These are divided into footwall western limb , hangingwall eastern limb and fold hinge lead-rich and zinc-rich domains, with the mafic rocks more complex in mineralogy than the siliceous rocks as mineralisation grades from outer Pb-Ag to inner zinc zones.
Longhole open stoping Paste backfill. The underground mine is accessed via a single surface portal with a decline extending to a depth of m below surface. The stoping areas are accessed by sub-levels developed on a nominal 25 m vertical interval. A number of ore passes, developed in ore, feed to a crusher loading level. Approximately two-thirds of the ore is crushed underground at the underground crushing station located at the base of the mining operation and hoisted to the surface.
Once stopes have been completely mined, they are backfilled with waste rock or paste. Paste fill is delivered from the paste plant to the underground workings for distribution via a conveyor system or a series of pipes, depending on the area to be backfilled. The paste backfill provides stability to the underground workings and allows ore beside the backfilled void to be extracted. Ore is crushed in an underground double-toggle jaw crushing facility with the crushed ore hoisted to surface and trucked to an open, conical stockpile.
In addition, some underground ore is trammed to surface using LHD units, where it is crushed and then placed on the same stockpile. The grinding circuit comprises a single 5. The AG mill operates in closed circuit with a pebble crushing circuit and primary hydrocyclones. The overflow from this circuit is treated in a talc pre-flotation step to remove talc and a significant amount of fluorine.
The concentrate from this pre-float step is disposed as a final tailing product. Flotation Agitated tank VAT leaching. The processes for extracting the silver, lead and zinc from the ore involve grinding, sequential flotation and leaching techniques that produce high-grade, marketable lead and zinc concentrates with a high silver content.
The Cannington process plant has a demonstrated throughput capacity of 3. The ore treatment process at Cannington uses primary underground and surface crushing.
Primary grinding and a preliminary talc pre-flotation step follow this. The concentrate from this pre-float step is Production :. Ore Reserves: UG Sulphide - Ore delivered to process plant. Data Access UserName is required.
