Malachite green (MG) separation from wastewater has always been a research focus in the field of environment. Removal of MG from aqueous solution using activated carbon has been studied or verified. Because of the different preparation materials and processes, the physicochemical properties of a...

In this study, the flotation behavior of malachite was investigated using carboxyl-functionalized carbon black nanoparticles (CB-NPs) as collectors in a hydrodynamically simplified Hallimond tube. We found that malachite floatability increased with increasing CB-NP concentration in the low range...

In this research, the flotation performance and adsorption mechanism of tert-butylsalicylaldoxime (TBSA) to malachite were studied by micro-flotation, contact angle, zeta potential, FTIR and XPS analysis. The result of micro-flotation tests indicated TBSA yielded high malachite recovery and sati...

Effects of common ions, namely hydroxyl ions and carbonate, on the adsorption and flotation of malachite with salicylaldoxime as a collector was investigated, making use of solubility, micro-flotation, zeta potential, contact angle, FTIR, and XPS measurements. The results suggested that hydroxyl...

In this study, the effects of calcium ions on the flotation of malachite with octyl hydroxamate collector has been investigated using micro-flotation, zeta potential, contact angle, adsorption, and particle size measurements. Although the adsorption amount of collector and the hydrophobicity of ...

Biochar is a promising material for facilitating the reclamation of oil sands process water (OSPW); however, how biochar properties can be optimized for metal removal from OSPW is not well studied. This study was conducted to determine relationships among feedstock type, pyrolysis condition, bio...

A novel method for manufacture of copper(II) oxide for copper electroplating solution is proposed in this paper. The copper(II) oxide was produced through two chemical reaction steps without sintering process after refinement of waste lead frame etching solution. The experimental major parameter...

Two sets of Ni-substituted calcium phosphate were synthesized by precipitation method at pH = 7 and at two different concentrations of ion carbonate (CO32-) in solution and Ni(II) concentrations lower than 15%. The produced solids were characterized by chemical analysis, infrared spectroscopy, x...

Calcium carbonate (CaCO3) may be used for lead removal. However, due to compact structure and high crystallinity of CaCO3, the utilization of CO32– is low and Pb removal only stays at the extent of physical adsorption and surface precipitation. In this research, a wet stirred ball milling proce...

Ceramic paper discs were made by employing a dual papermaking technique and by partially substituting cellulosic fibres by SiO2-Al2O3 ceramic ones. Ulexite (NaCaB5O6(OH)6·5(H2O)), extracted from the natural mineral, was added as a binder to give ceramic paper the necessary strength for its mani...

This study was carried out under atmospheric pressure and examined the kinetics of retention of SO2, a toxic gas, by waste ulexite ore (WUO) from a boron concentration plant, as well as the kinetics of passing B2O3 content of WUO to solution.The parameters of temperature, solid-to-liquid ratio, ...

Purposes of this study are to examine photon attenuation properties of concretes including ulexite and ulexite concentrator waste and to present an alternative shielding material in order to decrease the intensity of gamma radiation. In order to investigate the radiation transmission of these co...

Paraffin is mainly preferred as an organic phase change material (PCM) in thermal energy storage (TES) systems especially for cooling and heating of buildings implementations. In order to develop form-stable and thermally stable blends natural minerals (Colemanite, Ulexite and Mg(OH)2) were used...

A new two-step process was developed for the synthesis of tobermorite fiber from high alumina fly ash. The results reveal that high alumina extraction efficiency from the fly ash can be achieved in the first step and tobermorite fiber with excellent properties can be produced from the dealuminat...

In this study, conversion of municipal solid waste incineration bottom ash (IBA) into highly efficient sorbents for Cu(II) removal was reported. The formation of tobermorite induced by humic acid (HA) and IBA under hydrothermal condition was explored and its potential application for efficient r...

A polymer-mineral composite membrane of the mucopolysaccharide derivative, chitosan, and calcium silicate hydrate phase, tobermorite, was prepared by solvent casting and characterised by scanning electron microscopy (SEM) and Fourier Transform infrared spectroscopy (FTIR). The bioactivity and bi...

Compared with the traditional partition board, the superior properties of calcium silicate board are attributed to the generation of tobermorite, which can be influenced by many preparation conditions. The purpose of this study is to investigate the effect of Ca/Si ratio, and some others factors...

In this study, tobermorite was successfully synthesized from two kinds of industrial wastes by single step hydrothermal method. The structural and morphological changes during synthesis show that well-crystallized tobermorite can be obtained within 6 h at 180 °C in this system. The carbon impur...

The influence of different hydrothermal conditions and starting materials on a preparation of tobermorite was examined. Tobermorite is a mineral, which, thanks to its composition and properties, is an important phase in aerated concrete and it can be also used as an ion exchanger. Tobermorite cr...

Tobermorite is an important mineral analog of calcium silicate hydrate (C-S-H), the main phase formed by hydration of Portland cement, due to the structural similarity. As part of a broader study on the effect of aluminum substitution C-S-H, the synthesis and characterization of tobermorite with...
