Summary:

The Garpenberg supracrustal inlier is one of the most economically important inliers in the Bergslagen mining district. Silver and copper have been mined for more than 500 years (Tegengren, 1924) and are still extracted from the Garpenberg mine, yet nowadays as a by- product of Zn and Pb mining together with minor amounts of Au. The supracrustal inlier owes its name to the Garpenberg stratabound limestone-skarn hosted Zn-Pb-Cu-(Ag-Au) deposit, which at the time of writing is the largest known sulphide deposit in Bergslagen.

Proven reserves and mineralization is known to a depth of 1.5 km with new discoveries still being made (Boliden Mineral data). The mineralized system is 7 km long and comprises a number of ore-bodies that mainly occupy a 10-80 m thick altered marble horizon (Allen et al. 2003). Considerable mineralization is also located in the uppermost part of the stratigraphic footwall volcanic rocks, which generally show strong alteration proximal to the massive sulphide orebodies (Allen et al. 2003).


Mining Methods

  • Pillar mining
  • Cut & Fill
  • Sub-level stoping


Summary:

The Garpenberg mine is an underground mine where the ore is mined from between 500 to more than 1,200 metres below ground level. The main mining method is known as sublevel stoping. This means that the ore is mined in layers between two drifts (tunnels), which are driven through the ore body. Other mining methods include cut-and-fill mining, rill mining and residual mining of sill pillars.

In the case of sublevel stoping, holes for the explosives are drilled using vertical drilling rigs. The drill holes can be up to 28 metres in length with a diameter of 76 millimetres. For cut-andfill stoping and drifting, tunnel rigs with two booms are used.

A liquid emulsion explosive is used for blasting. The emulsion is mixed mechanically when charging. During sublevel stoping, a normal round produces approximately 10,000–20,000 tonnes of loose ore.

Loading ore from the sublevel stoping area takes place using remote-controlled LHD loaders. These can either be controlled entirely by an operator or controlled automatically, where loading and unloading are performed remote by an operator a CCTV camera system is used and the transport between is conducted automatically via a local WLAN system. Loading when drifting and cut-and-fill mining is performed with a wheel loader. The ore is transported using trucks to one of the two underground crushing plants. Ore and waste rock are transported by a contractor.


Crushing and Grinding


Processing

  • Flotation

Source: Subscription required

Summary:

There are two underground crushing plants where the ore is crushed in jaw crushers. The crushing plants are situated 700 metres and 1,087 metres below ground level. After crushing, the ore is hoisted to surface in a shaft. The machinery for the ore hoist is situated above the shaft installed in the headframe. The ore is unloaded into a bin in the headframe and then transported by a belt conveyor to an intermediate ore storage, which can hold approximately two days’ of production.

The ore is transported on belt conveyors from the ore storage to the grinding circuit. Water is added during grinding and the ore is ground in two stages, with autogenous grinding in the primary stage and pebble mill grinding in the second. Autogenous grinding means that the ore grinds itself without the addition of external grinding media. In the pebble mill, pebbles are added that have been extracted from the autogenous mill. The grinded ore is classified using screens and hydrocyclones. The coars ........
