  1. 1. 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.

  2. 2. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

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

    Author : Raoul Schmitt; [2021]
    Keywords : Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

    Abstract : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

  4. 4. Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips

    University essay from SLU/Dept. of Energy and Technology

    Author : Xun Luo; [2011]
    Keywords : torrefaction; biomass; poplar; Fuel Tree Chips FTC ; stump; heating value; grindability; Kinetic study; activation energy; pre-exponential factor; reaction order; Scanning Electric Microscope SEM ;

    Abstract : Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. READ MORE
