The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute. The denominator looks wrong; to convert to mass per hour should be multiplying by 60, not dividing by 60. Dividing by 60 should give mass
The time sequence of the concentration of residual amine in the tailings of each individual circuit is illustrated in Fig. 1.The sharp decrease observed from 11/11/2005 to 13/09/2006 was due to several factors, such as: circuit changes, increase in the throughput due to the addition of new mechanical cells, increase of the proportion of diamine in the collector …

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the …
For the ore handling, a minimum distance between the mine and the facility was assumed, so that the fuel consumption per ton of ore prevailed over distance. Then, taking into account the iron concentration in the feed stream of 3.63 Fe%, the specific energy per ton of iron ore was calculated (see Fig. 2). Download: Download high-res image (83KB)
Mine run ore is usually bulky to avoid fines and definitely requires a rail grizzly to limit the size of coarse ore fed to the jaw crusher. Two stage, open circuit crushing is satisfactory in the 200 ton per 8 hour production range. The resulting fine ore is smaller than ½" or ¾".
