Gold Tailings(金尾矿)研究综述
Gold Tailings 金尾矿 - To further enhance the practicality, other solid wastes (limestone tailings and gold tailings) were blended with SHAM to prepare the RLFC. [1] Materials and Methods: Fungi were isolated by serial dilution and spread plate techniques from gold tailings and their tolerance to different concentrations of As, Cd, Cr, Cu, Pb, Zn (as potential bioremediation candidates) was evaluated. [2] Two types of experimental samples were prepared: (1) gold tailings and silica sand to investigate the effect of NCC and (2) nickel tailings to investigate the effect of natural pozzolans. [3] Use CaO-Al2O3-SiO2 glass-ceramics from gold tailings in Hanyin as main raw materials, which were prepared by a melting method. [4] This paper presents a case study on the utilization of the patented Viper Filtration technology on gold tailings to overcome this challenge and shares the resultant full-scale plant design, highlighting the features designed to overcome cost and scalability deterrents. [5] Gold tailings (GT) and slag disposed of in the landfill affect the environment. [6] It is known that the tailings of gold mines have brought serious heavy metal pollution; however, the heavy metal pollution caused by gold tailings in specific geological environments and extraction processes still must be studied. [7] This paper presents a feasible way to design a low carbon footprint Ultra-High Performance Concrete (UHPC) with gold tailings based on the idea of full scale recycling. [8] An experimental method and apparatus was developed to measure the SFCC to estimate the SWCC for different mine waste tailings, including copper tailings, gold tailings, and oil sands centrifuge cake. [9] Arbuscular mycorrhizal fungi (AMF) are fungi from division Glomeremycota within the kingdom Fungi, which have a broad ecological range and symbiosis with a variety of vegetations, including vegetations in gold post-mining areas or gold tailings. [10] In this study the leaching of heavy metals from gold tailings was studied using sodium carbonate using gold tailings from Sibanye gold. [11] The cyanide species in the gold tailings are classified as free cyanide, weak acid dissociation, and metallocyanide complexes. [12] A conceptual case study for the disposal of gold tailings in Western Australia as a slurry, as thickened, or as filtered tailings, was considered.

[14] Received: 21 April 2019 Accepted: 19 July 2019 This paper prepares an aerated concrete (AC) with gold tailings as the main material, and explores the influence of different phases of autoclave curing on the microstructure of the proposed AC. [15] In order to realize the resource utilization of gold tailings (GTS), autoclaved aerated concrete (ACC) was prepared as the main siliceous material. [16]为了进一步提高实用性，将其他固体废物（石灰石尾矿和金尾矿）与 SHAM 混合以制备 RLFC。 [1] 材料和方法：通过连续稀释和铺板技术从金尾矿中分离真菌，并评估它们对不同浓度的 As、Cd、Cr、Cu、Pb、Zn（作为潜在的生物修复候选物）的耐受性。 [2] 准备了两种类型的实验样品：（1）金尾矿和硅砂来研究 NCC 的影响和（2）镍尾矿来研究天然火山灰的影响。 [3] 以汉银金尾矿中的CaO-Al2O3-SiO2微晶玻璃为主要原料，采用熔融法制备。 [4] 本文介绍了一个关于在金尾矿上使用专利 Viper 过滤技术来克服这一挑战的案例研究，并分享了由此产生的全规模工厂设计，重点介绍了旨在克服成本和可扩展性阻碍的特征。 [5] 在垃圾填埋场处理的金尾矿 (GT) 和矿渣会影响环境。 [6] 据了解，金矿尾矿带来了严重的重金属污染；但是，黄金尾矿在特定地质环境和提取过程中造成的重金属污染仍需研究。 [7] 本文提出了一种基于全面回收理念设计含金尾矿的低碳足迹超高性能混凝土 (UHPC) 的可行方法。 [8] 开发了一种测量 SFCC 的实验方法和装置，以估计不同矿山尾矿的 SWCC，包括铜尾矿、金尾矿和油砂离心饼。 [9] 丛枝菌根真菌 (AMF) 是来自真菌界球囊菌门的真菌，具有广泛的生态范围并与各种植被共生，包括金矿后开采区或金尾矿中的植被。 [10] 在这项研究中，使用 Sibanye 金的金尾矿使用碳酸钠研究了从金尾矿中浸出重金属。 [11] 金尾矿中的氰化物种类分为游离氰化物、弱酸解离和金属氰化物络合物。 [12] 考虑了在西澳大利亚将金尾矿作为浆料、增稠或过滤尾矿处理的概念性案例研究。 [13] 考虑了在西澳大利亚将金尾矿作为浆液或过滤尾矿处理的概念性案例研究。 [14] 收稿日期：2019 年 4 月 21 日接受日期：2019 年 7 月 19 日 本文以金尾矿为主要材料制备加气混凝土 (AC)，并探讨了高压釜养护不同阶段对拟建加气混凝土微观结构的影响。 [15] 为了实现金尾矿（GTS）的资源化利用，制备了蒸压加气混凝土（ACC）作为主要的硅质材料。 [16]
gold tailings dam
The presence of potential sources for metals in the form of aerosol through atmospheric transportation from gold tailings dams, coal mines, and coal-fired power stations increases the risk of water quality deterioration in the Johannesburg region. [1] Significantly high values were obtained from gold tailings dams. [2]从金尾矿坝、煤矿和燃煤发电站通过大气运输以气溶胶形式存在的潜在金属来源增加了约翰内斯堡地区水质恶化的风险。 [1] 从金尾矿坝中获得了显着的高值。 [2]
gold tailings dump
The use of the tool on abandoned tailings dumps in the study area revealed that gold tailings dumps are to be rehabilitated first than magnesite and copper tailings dumps. [1] Physicochemical properties of tailings were studied within 36 quadrats, each 30 cm × 30 cm, across two gold tailings dumps from three patches, namely; (1) patches consisting of BCs only, (2) patches with both BCs and vegetation, and (3) non-BCs patches without vegetation. [2]该工具对研究区废弃尾矿场的使用表明，黄金尾矿场比菱镁矿和铜尾矿场首先得到修复。 [1] 尾矿理化性质在36个样方内进行了研究，样方为30cm×30cm，横跨三个斑块的两个金尾矿堆，即； (1) 仅由 BCs 组成的斑块，(2) 具有 BCs 和植被的斑块，以及 (3) 没有植被的非 BCs 斑块。 [2]
gold tailings wastewater
In this study, the influence of saw dust based biochar on the removal of heavy metal ions contaminants in gold tailings wastewater was investigated. [1] This work evaluated the potential to use saw dust based bio char in the treatment of mercury contaminated gold tailings wastewater. [2]在本研究中，研究了基于锯末的生物炭对金尾矿废水中重金属离子污染物去除的影响。 [1] 这项工作评估了使用基于锯末的生物炭处理汞污染的金尾矿废水的潜力。 [2]
