  3. 2. Vibration signal analysis in comminution

    Författare :Yigen Zeng; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Comminution accounts for a significant part of the energy consumption and metal wear in powder manufacturing industries and as a result, it is a major cost factor. To maintain high efficiency, the operating parameters must be monitored and adjusted promptly to optimal values. LÄS MER

  4. 3. Tectonic Evolution of Taimyr in the Late Paleozoic to Mesozoic from Provenance and Thermochronological Evidence

    Författare :Xiaojing Zhang; Victoria Pease; Arild Andresen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Taimyr; sandstones; provenance; heavy mineral analysis; detrital zircon; apatite fission track; tectonic setting; uplift; Geology; geologi;

    Sammanfattning : The Taimyr Peninsula is a key element in the circum-Arctic region and represents thenorthern margin of the Siberian Craton. The Taimyr Peninsula is a late Paleozoic fold andthrust belt and preserves late Paleozoic through Mesozoic siliciclastic sedimentarysuccessions and providing an ideal location to investigate the Paleozoic to Mesozoictectonic evolution associated with the Uralian orogeny, the Siberian Trap magmatism andopening of Amerasia Basin within a circum-Arctic framework.

  5. 4. Leaching behaviour of rock materials and a comparison with slag used in road construction

    Författare :Mia Tossavainen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Leaching characteristics are used for the evaluation of secondary materials used in road construction. In order to form a basis for comparison of the leachability, Swedish rock material have been investigated using the availability test NT ENVIR 003. LÄS MER

  7. 5. Mechanical recycling of consumer electronic scrap

    Författare :Jirang Cui; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Consumer electronic equipment (brown goods), such as television sets, radio sets, and video recorders, are most common. However, recycling of consumer electronic scrap is only beginning. LÄS MER
