The impact of goethitic ore types ,
May 17, 2017· Difficult to separate ochreous goethite (in particular) from gangue by gravity separation due to the small difference in specific gravity This leads to lower Fe recovery in hydrocyloning, spirals etc Goethite is not amenable to magnetic classification Al and Si are key elements in the formation of sinter and pellet bonding phases (SFCA)...
Separation Process and Method
Separation is the main step of ore concentration Metal recovery and productivity largely depend on the separation process and methods Based on the physical and chemical properties of ore like its grain size, shape, color, density, friction coefficient, magnetism, moisture and electric property, several process and methods are available...
Process Amenability Studies on Goethite
