A new green hydrometallurgical method was developed for the selective extraction of copper and cobalt from spent lithium-ion batteries, using an aqueous two-phase system (ATPS) extraction technique. The method was optimized for the extraction of Cu(II) and Co(II), considering the influence of th...

Application of plant protection products (PPP) is a fundamental practice for viticulture. Life Cycle Assessment (LCA) has proved to be a useful tool to assess the environmental performance of agricultural production, where including toxicity-related impacts for PPP use is still associated with m...

An experiment was carried out to investigate the relative bioavailability of tribasic zinc (Zn) sulfate relative to Zn sulfate for broilers fed a conventional corn-soybean meal diet. A total of 504 1-d-old Arbor Acres commercial male chicks were randomly assigned by body weight of birds to one o...

Doloma (MgO.CaO) is being widely used in the manufacture of refractory products due to its favorable properties, such as the ability to refine steel melt, high refractoriness, high corrosion resistance in alkaline environments, as well as its favorable hot strength. On the other hand, hydration ...

Pore solution provides the physical and chemical environment for cement hydration, in which calcium, silicon, and hydroxyl ions released by dissolution of cement clinker are transferred into the hydration products such as calcium silicate hydrates (C-S-H) and calcium hydroxide (CH). Therefore, b...

Calcium-aluminosilicate-hydrates (C-A-S-H) and Mg-Al layered double hydroxides (LDHs) are widely identified as the two main hydrated phases formed in alkali-activated slag (AAS), regardless of reactant composition. In addition to the precipitates of microscale crystals, Mg-Al LDHs can be intermi...

Aluminum hydroxide (AH3) has recently been shown to be able to activate hydration in ternesite, a phase found in some calcium sulfoaluminate (CSA) cements.This study explored the capacity of a number of calcium aluminates (C3A, C12A7, CA and C4A3S¯) to activate ternesite hydraulic reactivity. A...

Water radiolysis is of particular concern for the conditioning of radioactive waste with cement materials. For safety assessment, water radiolysis issued from pore solution and hydrates must be considered because radiolytic molecular hydrogen H2 is produced, which is potentially explosive. Calci...

The main objective of this study was to investigate the effect of curing temperature and relatively humidity (RH) on the hydrates and porosity of calcium sulfoaluminate (CSA) cement pastes. A series of experiments including X-ray diffraction (XRD), thermogravimetric (TG) and mercury intrusion po...

The increasing of aluminum demand globally raises the interest in developing alternative technologies to produce alumina from non-bauxitic sources, especially clays. This paper studies the extraction of alumina from the kaolin ore excavated from the Irkutsk region, Russia through the leaching pr...

The high production of drill cuttings during oil well drilling operations is one of the main causes of the huge amount of waste created by the oil industry. Meanwhile, large amount of kaolin waste is produced during the kaolin mining processes. These wastes are usually deposited in landfills wit...

Beside lime and hydraulic binders, alkaline activation recently emerges as a possible solution for soil stabilisation. Unfortunately, soil reinforcement by alkaline activation requires additional reactive aluminosilicate sources under ambient temperature. In this study, we focus on kaolin as a s...

The synthesis of zeolite NaA from kaolin waste was conducted subjecting the reaction mixture to an aging step before autoclaving at high temperature. This waste, from Brasilian Amazon, is deposited in large basins and display excellent quality. In this aging step, the reaction mixture was agitat...

The occurrence of rare earth elements on clay mineral surfaces and the metallogenic mechanism is significant for mining and the leaching of ion adsorption REE ore. Through experimental isothermal adsorption of La onto the kaolin surface, it was found that the unit adsorption capacity could be di...

The development of an environmentally safe soybean-based adhesive with desired adhesion properties and technological applicabilities, but low cost, still remains a challenge. In this study, a facile and clean strategy was developed to improve the adhesion properties and technological applicabili...

Membrane separation technology is an important option for the treatment of contaminated surface waters but the relatively high cost of materials and membrane fabrication represent a significant obstacle to the wider use of membrane processes. In this study, we describe the development and testin...

As an important non-metallic mineral, cleaning and upgrading of coal-series kaolin is significantly important to the subsequent processing and utilization. In the work, the triboelectric separation was used to remove the organic carbon from coal-series kaolin, which is based on the differences o...

Wheat gluten composites with kaolin were prepared using compression molding, in the presence of glycerol as a plasticizer. The influences of kaolin content (0, 2.5, 5.0, 7.5, 10, 12.5 and 15.0 wt%) and probe sonication on the water resistance, degradation, mechanical, thermal and morphological p...

Metal oxychlorides of Fe, Cu, Bi and Zn were prepared and tested in heterogeneous Fenton degradation of 20 ppm of 2-Nitrophenol (2-NP) in the presence of ultrasonic (US, 20 kHz), ultraviolet (UV, 6 W, λ = 254 nm), and US/UV coupled irradiations. The different experimental conditions including t...

Inadequate disease control on citrus foliage and fruit is often attributed to insufficient fungicide spray deposition on target surfaces. This study describes a novel spray deposition assessment protocol and determines deposition benchmarks indicative of the biological effectiveness for better i...
