1. 1. Investigating the effect of grinding method on ore beneficiation behaviour

   University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

   Author : Mellisa Tanaka Mundida; [2023]
   Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

   Abstract : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. READ MORE

4. 3. Comparing different methods of measuring particle size for pharmaceutical excipients

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Jiawen Wang; [2022]
   Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

   Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

5. 4. Optimization of β-glucan levels in different oat fractions by milling and air classification

   University essay from SLU/Department of Molecular Sciences

   Author : Sumaiya Majid; [2018]
   Keywords : optimization; oat; β-glucan; air classification; milling; sieve analysis;

   Abstract : Oat (Avena Sativa) is an important crop worldwide which is mostly due to its various characteristics and nutritional profile. The recent progression in food nutrition have shown the importance of the different components in oats. Many health benefits of oats are attributed to β-glucan which have been demonstrated and well-studied over the years. READ MORE
