Jul 01, 1999· This review is a brief account of R&D results generated from microwave-assisted mineral treatments tests. The R&D results demonstrate that microwave energy has potential in mineral treatment and metal recovery operations such as heating, drying, carbothermic reduction of oxide minerals, leaching, roasting/smelting, pretreatment of refractory gold ore and concentrate, spent carbon
Froth flotation is the most effective industrial method used to separate fine-grained minerals. The main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation.
The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.

Before flotation, the ratio between the carbohydrates and lignin ranged from 3.1 (PfR70) to 92.9 (PfR100) (Table 1). In the DS samples, however, this ratio was found to be between 0.6 and 5.1 (data not shown). The presence of lignin-containing fiber fines could result in low values of degradability and methane yields (Steffen et al. 2016).
