Get PriceIn this work, we proposed a method forbiohydrometallurgical processing of mining (old pyritic flotation tailings) and metallurgical (slag) wastes to recover gold and other nonferrous metals. Since this processing allows the removal of toxic metals or at least decreases their content in the solids, this approach may reduce the negative environmental impacts of such waste.

Our pioneering technologiesprocess slag,a product of steelmaking, into useful environmentally beneficial aggregate products. Applications include road construction, asphalt, ready-mix concrete, cement, railway ballast,mining,filtration and agriculture. We carefully study the operations of each mill to custom design a comprehensive program for removing, transporting and processing slag.
Currently copper slags are mainly recycled for recovery of metals, 50 although slags with reduced copper contents (less than 0.8 wt.% Cu) are either discarded as waste or sold as products with properties similar to those of natural basalt (crystalline) or obsidian (amorphous). 60Processed air-cooledand granulated copperslagshave been used as fine and coarse aggregates for production of concretes, 59,63 and as …

Columbite concentrates and tinslagswith a high tantalum content (greater than 10 percent) are directly dressed in most cases by a wet chemicalprocess.Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy. The tantalum-rich ore or ferroalloy is then crushed, ground, and decomposed …
It can be produced by two methods. In the first, ores are selected on the basis of their acidity so that, on smelting, 70 to 80 percent of the manganese is recovered in the melt while aslagcontaining 30 to 42 percent manganese is also obtained. (Thisslagcan be resmelted to produce silicomanganese; see below.) The second method, which employs basic ores or fluxes, recovers 85 to 90 percent of the metal and generates aslag…
