“…4,5 The main components of most industrial solid wastes are SiO 2 and Al 2 O 3 , which are similar to the components of ceramic raw materials, providing a basis for their application in the preparation of high-value building materials. [6][7][8] Foamed ceramic siding is a new type of wall material whose fire-resistant, lightweight, high-strength, and other properties can reduce structural and foundation costs, optimize the beam and column structures, reduce the amount of construction, and improve building performance. [8][9][10][11][12] Currently, it is mainly made from industrial solid waste, ceramic raw materials, fluxes, foaming agents and other raw materials by high-temperature foaming.…”

With vanadium tailings and lead-zinc tailings as the main raw materials, gold tailings, waste glass powder, other fluxes and SiC foaming agents are added to prepare foamed ceramics. The effects of Ca and Mg in the fluxes of calcite, talc, and dolomite on the appearance, pore size, porosity, bulk density, and compressive strength of the samples were investigated and the mechanisms of the effects were analyzed. The XRD results showed that the sample consisted primarily of quartz, albite, augite, and a small amount of corundum. Calcite favors the formation of the augite phase, talc favors the formation of the albite phase, and dolomite combines the advantages of both. The formation of albite reduces the viscosity of the melt, and the formation of augite greatly enhances the strength of foamed ceramics. It has been shown that by adding 8% dolomite, a foaming ceramic with a bulk density of .561 g/cm 3 , a porosity of 62.77% and a compressive strength of 10.823 MPa can be prepared, resulting in a low-cost, lightweight and high strength foamed ceramic partition.

“…In acidic solutions, the surface hydroxyl groups of magnetite and hematite adsorb H + from the solution to form Fe-OH 2+ , making the magnetite and hematite surfaces positively charged, while some of the carboxyl functional groups in HA and FA molecules ionize to produce HO-HA-COOor HO-FA-COO -, exhibiting negative electrical properties. At this time, HA and FA molecules have opposite charges to the mineral surface, so HO-HA-COO -/ HO-FA-COOand Fe-OH 2+ on the mineral surface will generate electrostatic attraction force, while they will further interact with each other to form ligand exchange of HO-HA-OC-O-Fe/ HO-FA-OC-O-Fe 50) , and the reaction process is shown in (1)(2)(3)(4)(5).…”

“…Pellet ores become one of the high-quality furnace materials for modern metallurgy because of their uniform particle size, high strength, suitability for long-distance transportation and storage, high iron grade, good metallurgical properties, and conducive to improving the permeability of the smelting column and reducing the coke ratio 1,2) . The pellet binder is an essential additive in the production of pellets, which can not only bring the fine iron ore together to form uniform-sized green pellets but also significantly improve the pelletizing rate and metallurgical properties 3) .…”

Humic acid is inexpensive, and has a wide range of sources and a strong adsorption force with the surface of iron ore, and the size of its adsorption force is affected by some factors such as humic acid concentration, pH of the solution, and metal cations. The modified humic acid pellet binder (MHA) with strong adhesion and high viscosity was obtained through the separation and purification of solid wastes such as lignite and weathered coal and chemical modification treatment and successfully applied in the production process of iron ore pellets. After industrial tests, MHA can significantly improve the strength of green and dry pellets, less residue after high-temperature roasting, less metallurgical pollution, high strength of fired pellets, and can partially or completely replace bentonite.

“…There has been an emerging trend among the industries in procuring composite materials with low-cost reinforcements and low density [ 19 ]. Among several ceramic reinforcements used by different researchers, fly ash is an inexpensive suspended particulate matter obtained as a solid waste by-product during combustion in coal-fired thermal power plants and cement kilns in enormous quantities [ 20 , 21 , 22 ]. Hence, MMCs with fly ash as reinforcement gain more importance and are expected to overcome the cost obstacle for the extensive application of composite materials in the automotive and aerospace industries.…”

The authors researched the physical, metallurgical, and mechanical characteristics of A354 alloy (Al-Si-Mg-Cu) reinforced with 5, 10, and 15 wt% of fly ash metal matrix composites. A baseline alloy and three composites were fabricated by a liquid metallurgy route and poured into a permanent mold to obtain cast rods of dimension Φ32 mm × 156 mm. The metallurgical characterization of the developed alloy and metal matrix composites was conducted using energy-dispersive spectroscopy (EDS), field-emission scanning electron microscopy (FESEM), and X-ray diffraction. All the developed composites showed a pore-free nature, but only A354 alloy reinforced with 5 wt% of fly ash (AF5) possessed a homogeneous distribution and perfect bonding of the fly ash with the A354 matrix. Therefore, transmission electron microscopy (TEM) analysis was performed on the sample AF5. All developed alloys and metal matrix composites were subjected to hardness and mechanical property tests. It was observed that the AF5 sample had 170 ± 5.6 HV and tensile strength of 216 ± 2.3 MPa, 18.8% and 24.8% higher than the A354 matrix, but the ductility (6.5 ± 0.43%) was reduced by 23% from the baseline alloy. Finally, the fractography analysis was conducted on all the samples using FESEM to analyze the fracture mode. The fabricated 5 wt% fly ash-based metal matrix composite showed better mechanical performance than other samples. Hence, sample AF5 is suggested for manufacturing components in automotive and structural parts.
