Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite
Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!

Sjöströmsgruvan


Mined since the middle of 19th century sporadically. The magnetite ore is rich in Mn which is shown by the analysis made during WWII on the production; 30-36 %Fe and 10-13% Mn.
The area is still of interest to mining companies- LKAB made exploration in the -80ies and another company made core drilling in 2007.
