By means of staged ore milling, early separation between iron containing mineral and gangue, returning the intergrowth to next ore milling for further separation, separating milled material based on size, gravitational dressing of coarse grains, strong magnetic dressing and inverse floating of fine grains, the raw ore of 30 % grade is enriched ...
The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. It is a process of ore preparation, milling, and ore dressing ...
The question of how far to go with ore dressing refinements to effect a high percentage of recovery of the valuable constituents of the ore is an economic one. Each step in the concentration of an ore adds to the cost of the operation, and unless the value of the additional mineral recovered exceeds the extra cost of recovering it, the ...
The Difference Between Grade and Recovery. From the crude material to the final concentrate, an ore pass through many processes. At each step, the selective recovery of the valuable minerals results in concentration but also in losses. At each step, we need to know both the grade and the recovery to evaluate the projects success.
The present invention relates to ore dressing process for siderite, limonite and other weak magnetic iron ore. Siderite, limonite or other weak magnetic iron ore is made to pass through the magnetizing and roasting, magnetically separating and reverse floating process in a rotary kiln to obtain concentrated iron ore with TFe 62 69% and recovering rate 78 88%.
