Wills' Mineral Processing Technology, 8th Edition

P=pulp volume per ton solids (m³ t⁻¹):

$=\frac{1}{\mathrm{solids}\mathrm{density}}+\frac{100}{\mathrm{pulp}\%\text{solids}}-1$ (with solids density in t m⁻³ which is numerically equal to specific gravity).

Example 12.2

Estimate the size of cell for the following conditions related to the data for the Pb-ore (Appendix VI): feed rate 24,000 t d⁻¹ at 35% solids with ore s.g. 3.

Solution

F=1,000 t h⁻¹ (assuming 100% availability, otherwise multiple by 100/% availability)

T=12.5 min (5 min from Figure 12.59(b), giving ~ 95% recovery) × 2.5 (scale-up factor)

E=1/85 (default; i.e., 15% GH assumed) ...
