Abstract An increase in the oxygen content blast to a concentration of 26-28% during firing zinc concentrates KS furnaces leads decrease formation undesirable compounds ferrites and silicates, increases degree desulfurization, shortens time. At same time, it becomes possible load concentrate with high humidity into furnace, which will save costs for drying raw materials. Ultimately, an complexi...

Dioxin-like compounds including polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) are polyhalogenated aromatic hydrocarbons (PHAHs) that bio-concentrate, bio-accumulate and bio-magnify because of their hydrophobicity, and persistence in the environment. These compounds are formed as a result of incomplete combustion during cert...
