Research on the Recycling of Pulverulent Waste from the Ferous and Non-Ferrous Industry in Order tu Reduced the Pollution

Abstract:

Research conducted and presented in this paper have sought to reduce the pollution of the environment by harnessing the red sludge, waste ferrous powdered alumina factories existing areas. The red mud is a waste derived from the production of alumina due to the fact that the raw material bauxite contains besides Al2O3 and other minerals such as: hematite, quartz, calcite, rutile titanium dioxide, clay, and shows the red color due to hematite, the whose content can reach up to 45-50% (or 31-35% Fe). Because mineral constituents, containing red mud and water of constitution (approximately 10%). The valorification of red mud in metallurgy is not resolved so far appropriately in terms technical-economical, due primarily to the high content of arsenic than the limit allowed to minerals, which leads to storing it in ponds or throwing by some manufacturers in the sea. This waste has been processed along with other ferrous scrap, are still able powdery or petty, but having a content almost double iron (powder steel mill, mill scale, sludge from agglomeration - furnaces) in order to increase the concentration of iron and decrease the concentration of arsenic by-product.
