The paper presents the results of research on the influence of ilmenite mud waste coming from the production of titanium dioxide on the process of cement hydration by isothermal microcalorimetry. Quantitative analysis of the waste impact on hydration heat and kinetics has been conducted. The mud shows pozzolanic properties from the early hours after contacting the waste and cement mixture with water. The optimal amount of waste addition is within the wide range from 0 to 20 %. From this study, it is concluded that the waste from the production of titanium dioxide may be treated as a potential replacement for cement in concrete.

“…That is resolved by addition of such waste to cement production (Nocuń-Wczelik and Małolepszy 1995;Jarosz-Krzemińska et al 2015) or mixing it with concrete (Gougar et al 1996;Batchelor 2006;Giergiczny and Król 2008). Those methods are generally used in the disposal of such types of waste minerals.…”

Waste dolomite powder as an adsorbent of Cd, Pb(II), and Zn from aqueous solutions

et al. 2017

Sorption experiments of the Cd, Zn, and Pb(II) ions from aqueous solutions on waste dolomite powder were investigated. Waste dolomite powder is inconvenient during storage due to fine particle size; therefore, its practical application is needed. The sorption experiments were conducted with variables: initial metal concentration (500, 1000, and 2000 mg/dm3 ) in single-and multi-element solutions, adsorbent dose (0.5, 1, and 2 g), and contact time (45, 90, and 180 min). Results showed that dolomite powder removed all ions from experimental solutions. For multi-element solution, Pb(II) was adsorbed almost in 100% at the initial concentration equal to 2000 mg/dm 3 . For Cd and Zn, sorption properties decreased with the increase in the initial metal concentration and the maximum values at the initial metal concentration of 500 mg/dm 3 were 42 and 47%, respectively. The results suggest that waste dolomite powder can be considered for application as sorbent in wastewater purification.
