    Ore Dressing Techniques Courses

     CODE FEE  DAYS 
    GM-010 $5100 5 days 

    Course Description

    • The increasing demand for metals in a growing global economy is being met with decreasing ore grades which requires more efficient mineral extraction and recovery techniques. 
    • This course reviews the fundamental principles, and terminology of mineral processing techniques in details from initial classification, crushing, and grinding to dewatering and tailings disposal. 
    • The basic concentration techniques based on the physical properties of minerals such as magnetic, electric, gravity separation as well as froth flotation will be discussed.

    Who Should Attend ?

    • This course is for people with a basic to intermediate understanding of the principles of minerals processing techniquies. 
    • The course will serve as a refresher and as a way to integrate their specific knowledge into the broad technical aspects of the mineral processing sector. 
    • The course will be ideal for freshly graduated engineers.
