An operator friendly performance index for frother selection and optimization in coal flotation

, 2010
The demand-supply gap for indigenous met coal of acceptable quality in India has reached such a level that coal blends in integrated steel plants usually have a ratio of 70 to 30 between the imported and domestic. Met coal constitutes nearly 30% of steel
