    Abstract: The invention makes public an environment-friendly non-noise matte granulation technique. Melted matte flows out from the chute, then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte.

    Abstract: The present invention relates to a process for recovery of iron from copper slag. This invention particularly relates to a process for recovery of iron from a waste like granulated copper slag generated during the production of copper from its ores by a pyrometallurgical method. The present invention will be useful for solving the ecological and environmental issues with an added economic advantage of utilising the dump slag generated in the copper plants. Novelty of the present invention is process for the preparation of value added products viz grinding grade cast iron using copper slag generated during the processing of copper concentrate which otherwise is considered as a waste. Other novel features of the inventions are creating a homogeneous mixture of slag, reductant and flux so that reaction kinetics is more than conventional process. The reductant is used in such a way so that maximum recovery of iron can take place.

    Abstract: The invention relates to a method for processing steel slags and iron carriers such as, e.g., electric furnace slags, converter slags, fine ores, dusts from the production of steel and millscale, for recovering pig iron and environmentally safe slags. A molten slag bath and a molten iron bath are used at a volume ratio of between 0.5:1 and 1.5:1 and carbon carriers are introduced into the bath and hot air is top-blown. From the starting slags and iron carriers, a mixed slag having a basicity CaO/SiO2 of between 1.2 and 2.5 is adjusted, which is transferred into a hearth-type furnace or a ladle, wherein hot air is top-blown for afterburning at a post-combustion degree PC = CO 2 + H 2 ⁢ O CO + CO 2 + H 2 + H 2 ⁢ O of between 0.70 and 0.85 the CO formed from the carbon in the bath. The hot offgases from the furnace or the ladle are drawn off tangentially to the axis of the mouth of the hot air feeding lance.
