    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Minna Larsson; [2022]
    Nyckelord :3D model; limestone; cement production; resistivity; photogrammetry; Skövde; 3D modell; kalksten; cementproduktion; resistivitet; fotogrammetri; Skövde;

    Sammanfattning : Limestone is one of the main components of cement production. Limestone has been quarried in Skövde, Sweden, since the end of 19th century and Cementa AB has been operating the quarry since 1973. Aside from limestone, there are also Alum shale of Cambrian age, mudstones as well as bentonite layers of Ordovician age present in the quarry. LÄS MER

    Sammanfattning : Andrarums alunbruk satte stort avtryck i den omgivande skogen. Bruket krävde stora resurser av ved för att kunna processa alunskiffer till alun, vilket gjorde att behovet av vedresurser var stort. LÄS MER

  4. 4. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Niklas Gunnarsson; [2019]
    Nyckelord :Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Sammanfattning : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. LÄS MER
