“…The many kinds of waste products, such as junk, slags, and refractory wastes, make them a major waste-producing industry. Research by Mukhamedzhanova et al [ 6 ] showed that the addition of accurate quantities of modifiers to metallurgical wastes could allow for the fabrication of many kinds of building materials.…”

The utility of recycling some intensive industries’ waste materials for producing cellular porous ceramic is the leading aim of this study. To achieve this purpose, ceramic samples were prepared utilizing both arc furnace slag (AFS) and ceramic sludge, without any addition of pure chemicals, at 1100 °C. A series of nine samples was prepared via increasing AFS percentage over sludge percentage by 10 wt.% intervals, reaching 10 wt.% sludge and 90 wt.% AFS contents in the ninth and last batch. The oxide constituents of waste materials were analyzed using XRF. All synthesized samples were investigated using XRD to detect the precipitated minerals. The developed phases were β-wollastonite, quartz, gehlenite, parawollastonite and fayalite. The formed crystalline phases were changed depending on the CaO/SiO2 ratio in the batch composition. Sample morphology was investigated via scanning electron microscope to identify the porosity of the prepared ceramics. Porosity, density and electrical properties were measured; it was found that all these properties were dependent on the composition of starting materials and formed phases. When increasing CaO and Al2O3 contents, porosity values increased, while increases in MgO and Fe2O3 caused a decrease in porosity and increases in dielectric constant and electric conductivity. Sintering of selected samples at different temperatures caused formation of two polymorphic structures of wollastonite, either β-wollastonite (unstable) or parawollastonite (stable). β-wollastonite transformed into parawollastonite at elevated temperatures. When increasing the sintering temperature to 1150 °C, a small amount of fayalite phase (Fe2SiO4) was formed. It was noticed that the dielectric measurements of the selected sintered samples at 1100 °C were lower than those recorded when sintering temperatures were 1050 °C or 1150 °C.

“…An analysis of available worldwide publications on possible beneficiation of flotation waste indicates that the copper ore waste can be used in ceramics production because in combination with other components, brown and black pigments for ceramic glaze can be obtained. It has also been established that addition of flotation waste to ceramic mixtures causes reduction of shrinking of final products and elimination of water absorption [13,14]. Another method of reduction of the amount of copper industry waste is to use it for production of various abrasive material, cutting tools and devices and special-purpose tiles [4].…”

Mineral waste is a side effect of mineral industry activity. In the case of metal industry, flotation waste generated during ore treatment and slag produced in metallurgical processes are large in quantity. Implementation of effective methods for utilization of waste is one of priorities, leading to measurable economic and environmental effects. Taking these facts into consideration, four effectiveness models were proposed and analyzed in terms of waste management in current processes as well as waste utilization in new products. Calculation algorithms for all models have been developed.
