|---|---|---|---|---|
| Consumption rate.This rate x coating price determines the coating cost of a molded Ton | Kg /molded Ton | 0.6 ? 0.7 | 1.5 ? 2.5 | 0.7 |
| Mould Life expectancy. Dressing material helps to protect the moulds.Higher mould life represents less moulds used, lower copper costs and more smelting capacity | Molded Tons | 800 – 2.000 | 300 – 400 | 300 – 500 |
| Density. Lower densities mean easier material handling and a much more homogeneous mixing | gr/cc | 1.1 | 1.5 | 0.7 |
| Anode finishing. Better anode finishing implies a lower anode rejection rate and a better refinery acceptance | Very good | Acceptable | Marginal | |
| Anode Porosity | Low | High | Very high | |
| Anode Impregnation. An anode impregnated with mould coating represents a potential problem at the refinery due to electrolyte contamination | Very low | Very high | High | |
| Residues at Refinery. Unwanted, due to pipe clogging, filter and pump damage, settling on tanks. | Very low | Very high | Very high | |
| Operational Tolerance. Related with molten copper chemistry, copper and mould temperature and refrigeration | Very high | Very low | Low | |
| Silica Content.Lower silica content represents lower health hazard (silicosis) | % | 0.45 | 3.0 – 8.0 | Very high |
