ABSTRACT Brazil has immense potential in the production of quartz and its gem varieties consequently generating huge amounts of waste This research aims to utilize the amethyst quartz tailings from the Alto Bonito mine Brazil accumulated for decades in waste dumps through a specific study of cementitious mortar production considering the
The XRD analysis shown in Figure 5 was applied to the tailing sample revealing that the composition was mainly quartz SiO2 magnetite Fe3O4 orthoclase KAlSi3O8 and albite NaAlSi3O8
purge flow and split line and give disrupted sample transfer onto the column This will likely be seen as peak tailing and poor peak area reproducibility If the diameter of the liner is too large there will be a large dead volume which will increase the sample transfer time leading to peak tailing The quartz wool packing in a
An appropriate increase in the pulp densities and a suitable decrease in the initial pH facilitated increases in power generations and enhanced the recoveries of Cu from the tailing samples
Figure 1 represents the XRD patterns of tailing sample The peak value of tailing was categorized by quartz SiO2 lumanite clinozoisite sepentinite and chlorite
Minerals that correspond to the higher peaks were identified as quartz SiO 2 and minor peaks of Al OH 3 NaCl KCl MgO were also identified Fig 3 SEM image of iron ore tailing Full size image Fig 4 Specific gravity of unpulverized iron ore tailing sample is which is slightly higher than the specific gravity of conventional
Minerals 2022 12 1481 3 of 16 Basic Sample Characteristics The chemical compositions of the gold tailings samples are presented in Table 1 and
The CaO content is generally lower 13% compared to group 1 Gold mine tailing sample Nalu consists of Mg Fe rich minerals amphibole and pyroxene quartz chlorite and feldspars Sample WM is from an anorthosite mine and thus contains mainly quartz and feldspar minerals albite and anorthite
Among them quartz was the most abundant mineral in most tailings The major elements of tailings mainly included Si Al Fe Mg Mn Ca Na K and so on S existed in different types of tailings GSR 2 GSR 3 GSR 5 and GSR 14 were analyzed for every tailing sample and four gold standard samples GAu 2a Gau 9a Gau 10a and Gau 11a for
Enables a uniform and fast sample vaporization which could translate to peak tailing or the appearance of ghost peaks It is strongly recommended to buy liners pre packed with wool to ensure a reproducible packing position amount and density If needed quartz or glass wool can be bought separately and used to pack the liners
The study includes tailing sampling using a regular 3D approach each section of the sampling was chemically analyzed using ICP OES and with the data obtained a complete data base was generated used afterwards as input in a geostatistical model aimed to simulate the spatial distribution of copper and gold as metal of added value and of mercury
Terminator assisted solid phase cDNA amplification and sequencing TASseq uses a terminator terminal transferase and bead based platform to improve generation of single cell RNA seq libraries
C2 and C3 are taken from Lin Chong tailing and Feng Huangshan tailing respectively The primary ores can be classified into several types according to the characteristics of the main mineral coeval combinations sulfide altered quartz monzodiorite siderite sulfide quartz sulfide skarn and massive magnetite
The cationic starch with the best results was used in an aggregation test using a mixture of 70% hematite and 30% quartz values obtained from the result of the chemical analysis of the slime thickener s feed sample in order to analyze if the surface competitiveness among the hematite and quartz of the sample would affect the flocculant
The imbalance between raw materials of high economic importance and their supply has increased the search for new approaches to obtain valuable elements from mining tailings In this study the extraction of copper zinc and lead from sulfidic tailing in sulfate chloride media was investigated A 33 Box Behnken design was applied to evaluate
Table 4 shows the leaching results of the un sintered sample W2S8 green body and sintered sample W2S8 1200 °C/1h as can been observed from Table 4 there is little difference in leaching concentrations of Cu and Cd ions of the green body and sintered sample However compared with the green body the leaching concentrations of these heavy
The primary mineral phases of the sample were hematite muscovite mullite quartz anhydrite and microcline which were mainly responsible for the mechanical strength of the samples and the
Mine tailing deposits may result in environmental issues when abandoned and exposed to environmental conditions This case study focuses on the El Lavadero tailing deposit an abandoned mining environmental liability located in San Felipe de Jesús Sonora Mexico To forecast its acid mine drainage AMD generation potential the modified acid base
in tailing content in soil sample The permeability of contaminated soil also increased with the increase in tailing contents ranged from cm/hr to cm/hr The undrained shear strength C u of contaminated soil decreased from 646 kPa 5% of tailing to 312 kPa 20% of tailing suggesting that the presence of tailing has influenced the
Tailings are a significant concern due to their potential release of toxic elements into the environment posing risks to ecosystems and human health Therefore understanding their polluting potential is crucial for effective mitigation strategies This study evaluates the contaminating potential of eight tailing dams in the upper basin of the Puyango River in
Several barrels of the recycled tailing water sample were collected sealed and transported from the local tailing ponds about 25 km from the local concentrator in Yunnan China The removal of the slimes and residues of the organic reagents from the tailing water sample were also conducted before water chemical analyses and flotation tests
