   Nyckelord :Automated mineralogy; autogenous milling; grinding characteristics; mineral characterization; process mineralogy geometallurgy; blending strategies; energy consumption; throughput; scanning electron microscope SEM ;

   Sammanfattning : 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.

3. 2. Do Clay Minerals affect the thickener operationin Chuquicamata mine, Calama, Chile?

   Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Chris Soto; [2020]
   Nyckelord :Mine; clay minerals; mineral processing;

   Sammanfattning : Chuquicamata mine mineralogy has been studied performing both X-Ray Diffraction (XRD) and X-RayFluorescence (XRF) to determine whether there is any influence in the thickener operations. Thetargeted minerals were the clay group because of their detrimental effect on mining operations asmodify the rheology of the suspensions. LÄS MER
