Ph.D. project

Sensors for Raw Material Characterization

Sensors for Raw Material Characterization is part of Real Time Mining Project. The overall aim of Real-Time-Mining is to develop a real-time framework to minimize environmental impact and maximize resource efficiency in the European raw material extraction industry. The project will carry out research and demonstration activities which integrate automated sensor based material characterization, online machine performance measurements, underground navigation and positioning, rapid and sequential resource model update and underground mining system simulation and optimization of planning decisions.

My Phd project - “Sensors for Material Characterization” aims to define, develop and test potential sensor combination concepts for raw material characterization to provide relevant data for real-time online process control and optimization in small scale mining applications.

Sponsor of the project

Her PhD project is part of the Real-Time-Mining (RTM) Project. European Union Horizon 2020 program funded the RTM project. The overall aim of RTM was to develop a real-time framework to minimize environmental impact and maximize resource efficiency in the European raw material extraction industry. The key concept of the research was to promote the change in paradigm from discontinuous intermittent process monitoring to a continuous process and quality management system in highly selective mining operations. The project started in April 2015 and completed in May 2019.

Supervision

Feven supervised the following MSc. and BSc. projects

  • EGEC-D/IP Integrated Project (Environmental Management / Mine Closure) 
  • The influence of environmental conditions on the use of sensor technologies for in-situ material characterization - A review
  • The applicability of Raman spectrometry for real-time characterization of sulphide ore
  • The influence of sample moisture content on infrared spectral data
