This paper provides a breakdown of operating costs in 63 mines by dividing them into three main categories: mining, milling, and general and administrative (G & A) costs. The study looks at patterns in mining type, mill processing type, mineral type, and the differences between costs expressed in feasibility studies vs. operating mines. The ...

If the rougher stage for this circuit is designed only to meet the tonnage of 50 t/h with a grade of 2.5%, it will be associated with a lot of difficulties since increasing the amount of metal in the input, in addition to the design parameters, will affect the operating parameters such as the type and amount of chemicals, and pulp density.

Sphalerite is the most important zinc mineral, from which more than 85% of zinc is produced. Most commercially viable zinc ore bodies contain zinc above 4% and rarely above 20% in mass, although zones of pure sphalerite can occur [1].With the gradual depletion of high-grade ores and the finer dissemination of values in lean ores, it has become imperative to process …

The influence of operating parameters comprising superficial gas velocity, slurry solids% and frother dosage/type on S b and flotation kinetics was discussed. Analysis of available industrial data suggested that S b and ε g were related by S b = 4.46ε g over the range 30 < S b < 60 s −1 and 7% < ε g < 14%.

Mineral flotation is a size dependent process; fine, intermediate and coarse particles show different flotation behaviour. It has been reported that efficient flotation of mineral particles occurs for particle diameters in the range of 10–150 μm (Shergold, 1984, Nishkov and Pugh, 1989).Below the lower and upper limit of this size range, there is low or poor recovery of …

Introduction. Froth stability plays an important role in determining selectivity and recovery in flotation (Farrokhpay, 2011). It should be noted that froth with very high stability is not desirable because in addition to recovering the particles attached to the bubbles, it creates favourable conditions for entrainment (Zheng, Franzidis, and Johnson, 2006).
