1. 1. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Morgan Eliasson; [2023]
   Keywords : Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

   Abstract : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. READ MORE

3. 2. Identification and strength classification of weakness zones in the Garpenberg mine based on measurement while drilling (MWD)

   University essay from Luleå tekniska universitet/Geoteknologi

   Author : Ioannis Peroulakis; [2022]
   Keywords : Drilling; MWD; Garpenberg; Mining; Geotechnics;

   Abstract : Boliden’s Garpenberg mine produces Zn-Pb-Ag(Cu-Au) using a sublevel stoping with pastefill mining method. The orebody is strongly affected by the existence of weakness zones mainly consisting of Talc Schist and Phlogopite Schist which affect the design, planning and production of the stope. READ MORE

4. 3. EXAMINATION OF MICRO-SCALE SULFIDE DISTRIBUTION FOR THE GOLD MINERALIZATION IN THE LAPPBERGET DEPOSIT, GARPENBERG MINE, SWEDEN: TOWARDS A GEOMETALLURGICAL APPROACH

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Leo Barbosa; [2021]
   Keywords : Gold characterization; gold as by-product; Lappberget ore; Garpenberg Mine;

   Abstract : Ore characterization studies are of great importance to the mining industry, especially when dealing with precious metals by-products. It is a way towards increasing mining efficiency. READ MORE

5. 4. A process mineralogy study of grinding characteristics for the polymetallic orebody, Lappberget Garpenberg

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Gustav Lood Stark; [2021]
   Keywords : Automated mineralogy; autogenous milling; grinding characteristics; mineral characterization; process mineralogy geometallurgy; blending strategies; energy consumption; throughput; scanning electron microscope SEM ;

   Abstract : Most of the high-grade ores have been depleted globally, thus the effective processing of the low-grade and complex ores require a comprehensive mineral characterization through the process mineralogy/ geometallurgical approaches. 30-70 % of the total energy consumption in mining comes from the comminution step in mineral processing.

6. 5. Investigation of the zinc re-grinding circuit at Boliden Garpenberg

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Nils Merum; [2021]
   Keywords : Flotation; re-grinding; Garpenberg; Boliden;

   Abstract : Boliden’s mineral processing plant in Garpenberg wanted to investigate their zinc-regrinding circuit. The re-grinding circuit had performed subpar when running as the total recovery of zinc was lowered and problem with the dewatering of the final concentrates was also noted. Therefore, the zinc re-grinding circuit is currently not being used. READ MORE
