    Abstract : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. READ MORE

  3. 3. Characterisation of kraft pulps by size-exclusion chromatography and kraft lignin samples by capillary zone electrophoresis

    University dissertation from Institutionen för pappers- och massateknologi

    Author : Elisabeth Sjöholm; KTH.; [1999]
    Keywords : ;

    Abstract : In the present thesis two analytical methods forcharacterisation of underivatised pulp and lignin samplesobtained from kraft pulping of hardwood and softwood areevaluated. The first method is the use of lithiumchloride/N,N-dimethylacetamide (LiCl/DMAc) for dissolution andsize-exclusion chromatography (SEC) of pulps. READ MORE
