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

3. 2. Comparison of Level Control Strategies for a Flotation Series in the Mining Industry

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Frida Norlund; [2022]
   Keywords : Technology and Engineering;

   Abstract : Separating valuable minerals from waste rock is an important step in the production of metals. This is for copper ore done through a process called flotation. A flotation series consists of tank cells in series where the minerals are collected in a froth on top of the cells. READ MORE

4. 3. A bonded discrete element approach to simulate loading with hydraulic mining excavators

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Carl Andersson; [2021]
   Keywords : DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

   Abstract : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. READ MORE

5. 4. 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.

6. 5. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Jamal Choudhry; [2020]
   Keywords : DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

   Abstract : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. READ MORE
