  • Grinding Mineral Processing

    The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

  • THE EFFECT OF GRINDING FINENESS ON THE RESULTS OF

    One of the influential parameters on the process of flotation concentration is a coarseness of parti-cles and openness of mineral resources. In the process of flotation concentration of ore from the de-posit Veliki Krivelj, the grinding fineness since the opening of the mine in 1982 has been maintained at values around 58% -0.074 mm.

  • Grinding capacity enhancement by solid concentration

    May 01, 2002· The main problem limiting the grinding capacity at El Teniente was the rope-type discharge occurring at 78–80 wt% solids concentration. At present the use of inclined hydrocyclones, 26 in. diameter, allows the operation of up to 80–82 wt% solids concentration at the hydrocyclone underflow without troubles.
