“…The purified water can be applied in the leaching process again [23]. Likewise, there are Fe 3+ and Mg 2+ in the acid leaching solution; NaOH can be used to adjust the pH in order to make the Fe 3+ and Mg 2+ precipitate in the form of Fe(OH) 3 and Mg(OH) 2 , and the by-product is NaCl, which can be separated by cooling crystallization method.…”

“…Likewise, the hydrochloric acid leaching leachate usually includes Fe 3+ and Mg 2+ . Sodium hydroxide can be added into the leachate to adjust acidity in order to make Fe 3+ and Mg 2+ precipitate in the form of Fe (OH) 3 and Mg (OH) 2 to remove the Fe 3+ and Mg 2+ from the leachate. Table 7 shows analysis results of main metal ions in the leachate before and after precipitation.…”

An environmental procedure to extract titanium components and metallic iron from Ti-bearing blast furnace slag is accomplished via three steps, which are high-temperature modification, gravity separation and hydrometallurgy method. The behaviors of metallic iron during the high-temperature modification process are studied. The feasibility of separating rutile from the matrix phase are investigated; based on the feasibility analysis results, the gravity separation experiment is carried out in order to improve the TiO 2 content in the slag. The leaching behaviors and kinetics of non-titanium components in the concentrate of gravity separation are investigated. The activation energy of the leaching process is 62.868 kJ/mol, and circulatory leaching and preparation of synthetic rutile experiments are implemented. Finally, an environmental technological route is proposed for comprehensive utilization of Ti-bearing blast furnace slag.

“…In addition, in case of a breakdown or the need for refurbishment or modernization, such a backfill can be removed without the use of heavy equipment. The universality of use of copper slag proves the possibility of its use in highstrength concrete (Al-Jabri, Hisada, Al-Saidy, & Al-Oraimi, 2009) as well as in ultra-high performance concrete (Ambily et al, 2015).…”

The article presents the results of testing the effect of partial replacement of sand with fine copper slag waste on the thermal properties of hardened concrete. The impact of the replacement on mechanical properties (ie. compressive and tensile strength of concrete) was also investigated. The thermal properties of the concrete were determined using the non-stationary method with the ISOMET 2114 device. Tests were performed on concrete containing three different types of cement (CEM I, CEM II and CEM III). A total cement content of 360 kg/m 3 was assumed in the compositions of all concrete mixes with a water-cement ratio of 0.45. Replacing 66% of the sand volume with copper slag waste caused a decrease in thermal conductivity by about 4-8% in relation to the reference concrete. In addition, the compressive strength of concrete containing copper slag increased by about from 4-21% in relation to the reference concrete.

“…It is possible to manufacture high-quality concrete, improving its properties compared to concrete with sand [14,15]. It has been found that copper slag used as sand substitution significantly improves consistency and compressive strength of concrete without changing the amount of mixing water [12,16].…”

Abstract. The paper presents results of tests of lightweight concrete made with copper slag waste material as fine aggregate (fraction 0 -2 mm) and two types of light aggregate (fractions > 2 mm). Six series of concrete with three w/c ratios (0.50, 0.55 and 0.60) and two variants of cement content (200 kg/m 3 and 300 kg/m 3 ) were manufactured. Reference concretes were also prepared in which copper slag waste was replaced by the same mass of river sand. To maintain similar densities of mixtures with copper slag in comparison to those with sand mutual proportions of both lightweight aggregates were modified. On concrete specimens compressive strength was tested as well as the open porosity was determined by drying to stable mass at 65°C. The concrete bulk density in saturated and dried state was also determined using hydrostatic weighing. The obtained results were compared with the results of the reference concrete tests. Results have shown that replacing sand with copper slag waste in lightweight concrete does not negatively affect their strength but may slightly increase their porosity.
