Ireland has a long history of mining. Records of mining here go back as far as the bronze age approximately 5,000 years ago. At this time the southeast of the country was a major copper producing area and gold was also Clay Minerals☆ J.M. Huggett, in Reference Module in Earth Systems and Environmental Sciences, 2015 Fibrous Clays (Sepiolite and Palygorskite) (2:1) Sepiolite and palygorskite (also known as attapulgite) are structurally different from other clays in two ways.Firstly, the tetrahedral sheets are divided into ribbons by inversion though they are still bonded in Attapulgite an overview ScienceDirect Topics
The rapid development and application of nuclear technology have been accompanied by the production of large amounts of radioactive wastes, of which Sr is a typical nuclide. In this study, six The pristine attapulgite (Atta) was pretreated by thermal and acid activation process in order to improve the loading capacity of phase change material (PCM). A series of pretreated Atta-based composite PCM was prepared combined with different kind of fatty acids. The XRD, FT-IR and XRF results shown that the pretreated process increased the Attapulgite: a promising natural mineral as carrier material
As the demand for metal minerals grows, the number of mine tailings increases dramatically worldwide. Toxic heavy metals (HMs) in tailings tend to migrate into the environment and cause serious damage to the surroundings. Possible eco-friendly solutions for the in situ stabilization of HMs in tailing ponds are required to reduce their The main objective of the present study is the investigation of the adsorption efficiency of raw and heat-treated attapulgite clay for removing Pb and Cu from aqueous solutions. The removal of each metal was studied separately with the use of one-substance solutions. The effect of certain factors, including solution pH and ionic Geosciences Free Full-Text Adsorption of Pb and Cu from
Ludwigshafen, May 22, 2019 BASF has implemented process improvements to provide a reliable and stable supply of its attapulgite offerings. The enhancements at their site in Quincy, Florida include expanding of milling and product packaging capabilities for coarse gel, fine gel and granular materials, as well as improved logistics in shipping the mineral To enhance the sorption efficacy of attapulgite for heavy metals, mercapto-functionalized attapulgite (ATP-SH) was synthesized with mercaptan functional groups. When the mass-to-volume ratio of calcined attapulgite (ATP-C) to 3-Mercapropyltrimethoxysilane (MPTMS) was 1 g:0.5 mL (ATP-SH-0.5) and the pH was Minerals Free Full-Text Preparation and Characterization of
Attapulgite is a water-rich magnesium aluminum silicate clay mineral with unique layered chain structure and nanorod-like crystal morphology [1], [2]. The crystal structure of attapulgite belongs to the 2:1 type. The basic structural unit is composed of double chains of silico-oxygen tetrahedron, which are connected by oxygen atoms.In the United States, attapulgite can only be mined in southwestern Georgia and northern Florida. The mineral takes its name from the town of Attapulgus, GA, where it can be found in abundance. BASF operates its attapulgite mines in this area, with the manufacturing facility located approximately 17 miles south of Attapulgus in Quincy, Attapulgite mines offer highly absorbent, rheology-stable minerals
Attapulgite is a type of fibrous rod-shaped clay, with palygorskite as the main mineral component. Palygorskite has a chain-layered structure and is composed of a water-containing magnesium-rich aluminosilicate with a chemical formula of (Mg, Al) 5 [(OH) 2 (Si, Al) 8 O 20]8H 2 O (Shi et al., 2009, 2017).Attapulgite is distributed in many places The clay mineral attapulgite derives its non-swelling needle-like morphology from its three-dimensional crystal structure. The shape and size of the needles result in unique colloidal properties, especially resistance to high concentrations of electrolytes, and give high surface area, high porosity particles when thermally activated.

Humic acid generally shows strong absorbance in the UV–vis region. Wavelengths at 250 and 280 nm are often used to study the spectral properties of HA (Bai et al., 2008).The UV–vis absorbance spectra of HA with varying concentrations recorded at pH 7.0 are shown in Fig. 1. Fig. 1 indicates that there are no obvious peak maxima or In this study, attapulgite-supported nano zero-valent iron (nZVI@ATP) was synthesized by a liquid-phase reduction method using active attapulgite (ATP) as raw material, and used for Pb2+ remediation Nanomaterials Free Full-Text Mechanism

In this paper, the microstructure of attapulgite clay minerals and acid-modified attapulgite clay minerals are qualitatively and quantitatively analyzed by scanning electron microscopy. Jian Zhou, Yiliang Deng, Yang Cao et al 2014 Microstructure experimental study on consolidation process of saturated soft soil in Hangzhou [J] case for attapulgite. Different studies have been carried out on the effect of grinding on clay minerals, such as the effect of micronization on the crystalline structure of kaolinite (Suraj et al., 1997). Ball milling was found to be a relatively low-impact process where the structural changes in the mineral were minimal, whereas use ofAN ASSESSMENT OF THE SURFACE PROPERTIES OF
The disappearance of calcium carbonate peaks at (29.3556) 2 Ɵ was observed due to the purification of Attapulgite from other mineral impurities using sodium methyl acrylate, while the peaks ofthen transport the clay to processing plant. Processing involves crushing, drying, classification and pulverizing. Specifie characteristics of the palygorskite product can be enhanced by certain additional processes. For example, extruding the palygorskite, to separate the elongate particles, and adding i -2% of magnesium oxide can improve thePALYGOWSMITE (ATTABULGITE) IARC
